Musso wagon tips 'n issues!

Unread post by drz400y » January 8th, 2012, 8:55 pm

Here are a few tips for those that are proud owners of the very unloved Musso.

A few common problems and fixes

1. Problem- Engine cranks for too long after sitting for more than a few hours.
Cause- O'rings that seal the fuel pump to surge tank are worn.
Fix- Remove fuel pump/surge tank unit (access is below rear seat on passenger side). Open surge tank by releasing
3 tabs. Remove fuel pump from inside, replace all o'rings and reassemble.

2. Problem- Engine stumbles on accel or high fuel consumption
Cause- MAF sensor dirty or faulty
Fix- Clean or replace MAF sensor with new Bosch unit only, do not use aftermarket.

3. Problem- Engine randomly shuts off and will not restart.
Cause- OVPR has dry solder joint, corrosion or burnt coil.
Fix- Remove OVPR, located beside brake booster on Ssangyong models or under centre console bin on Deawoo models.
Gently open lower part of alloy cover and remove internal component. Inspect for corrosion. If no corrosion is found,
reflow solder joints with a soldering iron. Refit to vehicle.

4. Problem- Clicking noise in reverse gear.
Cause- Reverse gear clutch packs worn. This can also lead to entire failure of reverse gear, usually noticed as a binding
when trying to reverse like the park brake is still on.
Fix- Not an easy DIY unfortunatley. Transmission must be removed, pump and reverve assembly stripped, clutch packs
replaced and then re-installed. Approx parts cost is $250 and about 8 hours labour. Do not be talked into a tranny
rebuild at this stage unless there is something else major wrong.

5. Problem- Sluggish 2-3 shift
Cause- Improperly calibrated valve body form Benz.
Fix- Replace K2 accumulator spring with kit from Benz. Relatively easy DIY, if you need more info, shoot me a pm.

6. Problem- Front suspension collapse
Cause- Upper control arm nuts re-used after having work done in this area. Nuts come loose and let the control arm
come off the pivot bolt.
Fix- New nuts must be fitted, these are a one use only item. Replace with new and use Loctite to secure.

7. Problem- Overheating under load.
Cause- Other than the usual culprits like blocked radiator, thermostat to operating correctly or bad radiator cap.
The biggest overlooked item is the viscous fan hub. As with any vehicle from the early 1980's on, the viscous fan has
done alot of work and the silicone fluid inside is either almost completely leaked out or just plain worn out.
Fix- Remove the viscous fan hub. There are 2 options, you can either fit a new Benz unit or refill your existing hub.
Unlike Toyota's, the Benz unit is sealed and can not be disassembled. To refill, drill a 4mm hole in the front of the hub,
sit it in the sun for a few hours and let the old fluid drain out. You can buy the fluid from Toyota or alternatively, use
radio control car diff oil. It is a silicone fluid, the same as what comes in the Toyota bottle. It can be bought in 3000,
5000, 6000, 75000 and 10000 CST. I have had best results with 7500CST, you will need about 25-30mL. Once you
have filled the hub, fit a fine thread screw to the hole you drilled previous using silastyc or pipe sealant to stop the screw
leaking.

These are all pretty straight forward jobs that a good diy bloke could get done, other than the reverse gear fix. Once you have these things sorted, the Musso is a very capable and very reliable vehicle. It is somewhat limited by ground clearance, but no more so than any other IFS 4x4.

Ours is the 3.2 petrol 6 automatic. Plenty of power for towing our camper trailer with average fuel consumption being 15.4 L/100km loaded with the 3 kids, the camper and all the crap you need for a week away.

There are a lot of bad stories regarding the Musso, but most I have found are due to lack of knowledge in how to properly maintain the vehicle. They can be a very cheap alternative in the 4x4 world and with a little bit of smarts a Musso will get you a long way off the beaten track.

If anyone has questions regarding the Musso, reply here and I will be happy to help.

Cheers Eric

Hey drz400y,

I am a Musso owner as well. Mine is a 1998 version 3 model (Last of the Ssangyong Musso's before going over to Daewoo) also I am the president of the Ssangyong 4WD Club of Australia. If you are a forum member over there, what is your username?

Thanks for the tips,

I recently bought a 1998 Musso for a what I think was a bargain having known not much at all about the vehicle. We took it off road a couple of weeks ago and I was very impressed at how it handled the tracks. We went on some quite challengeing tracks, (spent half the time in low range 2nd and 3rd gear) and it didn't miss a beat, its stock standard with road tyres , would have been a different story on a wet track I'm sure but its going to be a good project. The car has done about 220000ks so I'm sure your tips will come in handy at some stage.

Do you know what other vehicle makes wheels fit the musso? I've got 17" mag wheels on it with road tyres but I'm thinking of getting a set of 15" steel rims to fit some 31" AT's, I figure going to a 15" the tyres will be cheaper and I'll have more choice.

Cheers
Mark

Old thread I know but can't seem to find to much on them, I've just bought a 97 auto 3.2 for a good price & would like to know the pro's & cons. Previous 4b's have been FJ55 Cruiser, 2 series 1 Paj's, 3 Ford Explorer's, a 91 GQ rb30 & a Disco 1 V8, am thinking/hoping the Musso would be as capable as the Explorer's at least...........? :D

Good day all,

I'm having a lot of trouble finding anyone who understands Mussos. I've got a 1997 2.9 Ssangyong Musso.

In short... all the gears disappeared about a month ago. After towing it back home the gears worked fine. Was told to replace clutch so did.

Two weeks later and its done the same thing. The breakdown service cured it temporarily by switching it to 4H drive. Managed to drive it home at which point the 2H drive was working as well. The engineer reckons its transmission electrics (switch or loom or transmission "motor"). I've already spent a fair few sheckles on replacing the clutch and just wanted to know if anyone could back up or refute what he's saying. Problem is I'm in the UK and these Mussos are pretty rare and therefore no real expertise to hand.

Any info would be appreciated. Tx!

Don't know what sort of work yours has done but we had trouble with the transfer box & it would only drive in low range as in normal it was cluncking off & on & & occasionlly loose drive altogether. Mine had done a lot of towing by previous owner, towing comp 4x4 (on trailer of course LOL) over years all over eastern states. The main shaft had worn slightly, enough that a 4x4 gear & transfer box specialist mechanic pulled it apart 6 times before he found it. Luckily he had quoted me a max for the job & kept to it LOL

Hello all, is this thread still active? I am seeking some info in regards to my 98 Musso. The naysayers keep telling me to get rid of it, but I have found that most problems I have been able to fix with the right advice, the problem being finding the right advice -) and parts I might add, Ssangyong are living in a dream world asking the prices that they do.

My current to fix projects are a water leak at the back of the block, pretty sure that it's water due to the drip rate, there is another weep at the front of the block at about where the head gasket is, this appears to be a water/oil mixture given the colour. I recently had a compression test done on it, it has started overheating at idle since, not sure why but it could be that the head gasket has finally given way.

The other quirk that I am trying to solve is that the transmission won't select B, the lowest gear. This problem correlates with the gear shift sensor not releasing the gear shift from park when applying the brake pedal, I need to use the override switch inside the console. I had a second hand motor put in the car when I warped a head, when the motor was installed the transmission selected bottom gear and the park gear released when applying the brake, at the time I placed it into low range and tried both again, they worked, I then placed vehicle into high range and both the bottom range selection and the park select stopped working. Intermittently both have worked again, and both work simultaneously, they only work for a fraction of time though before reverting back to beng faulty.

Thanks to those of you who read this, and if you have any knowledge of the faults I would appreciate hearing from you.

Cheers
Darron

Which motor is in yours? Petrol or diesel?? Altho I guess it doesn't really matter, cos whichever it is it still sounds like you've got a head leak in there. A compression test won't necessarily reveal a leak from the water jacket, altho if you've got a water/oil weep up front you should be able to see signs of the coolant in the oil - small patches of whitish material that sorta looks like yoghurt, maybe under the oil filler cap or on the dipstick; or it could just show up as overheating &/or loss of coolant fluid over time from the overflow container. As for the overheating itself, that could be a failed or tiring fan hub, they do tend to get tired every hundred thousand km or so.

Re the transmission, that sort of problem is usually associated with a poorly adjusted selector or worn bushes in the selector mechanism. The fact that they still work occasionally suggests that it might be something like that & that you fluke it every now and again, but not reliably. Apart from that, your problem leaves me guessing - sorry :(

Hey Peter-)

How's Jules??

Thanks for your reply, you are more familiar with the vehicle than you probably recall, it used to be part of the hills club that you founded-)

I am pretty confident that it's a head gasket, the number 6 pot is down to 110 in comparison to 150 at the front. As always, have to weigh up the cost of repair in comparison to the likely resolution of the problem.

Hope all is well with you
Darron

Ha! Small world, innit Darron!! :thumb: I did wonder when I saw the email address... ;) You still got my phone number?? Gimme a yell (or drop me a PM) I'm not far from home most days now ('early onset' old age & infirmity sneaking up on me - paying the penalty now for doing too much exciting stuff when I was young, foolish, & bulletproof! :( ) & Jules just happens to have a week off atm too, if you've got any free time.

Buuut, even if you can't make it in the next week or so it's still probably worth a visit sometime (with a little advance notice) cos I just happen to know this other Musso that calls in here fairly regularly that could benefit from meeting yours, & now it sounds like yours might also benefit from meeting this other one (or at least meeting its owner) - besides, who knows, if the two Musso's meet, they might end up making beootiful music together. So let's see if we can get them together. :sillywink:

It really does sound like you've got a head gasket problem doesn't it? As for the trans problem, parking the two alongside each other and comparing the state of the selector linkages might be enlightening... want to give it a try??

'Tis a small world Peter, smaller now with the web at our finger tips, but larger in a geographical sense. Just to clarify, the family and I have moved to Port Lincoln, I was offered the opportunity of a transfer and a higher duties role and figured what the heck-)

I'm thinking that I don't have your number, pretty sure that I have Jules' still though. It would be worth calling just to see how he and the family are travelling. Not good to hear that you are feeling home bound currently, that must be frustrating, I to have felt some pangs and pains that I'm not familiar with, hoping if I ignore them for long enough they will go away by themselves.......

I am trying to order some parts for the beast online, unfortunately Ssangyong and Four Green appear to be the common suppliers and both are quoting ridiculous replacement prices. I recently purchased a headcover gasket set and timing cover gasket for $90 delivered, not offensive price by any stretch, however I was informed that the price to purchase the same products as of now is in excess of $400.00. Stupid really.

Having the two to compare against would be excellent, we are currently making regular trips back to Radelaide, so if I can get the beast operating well enough to make a return trip I will certainly make contact and see if the option is still viable, i would love to know why the transmission/park selector are playing up and why they correlate at all

Good to chat Pete, hope to see you and Jules again in the near future

Well, I guess that Port Lincoln musta needed someone special to keep all those holidaying at 'Her Majesties Pleasure' in line, & if they also want to pay you more to do it, then why shouldn't it be you!! :thumb: Port Lincoln is a nice place (don't know about where you're working tho!) and there's some good 4Wheeling around that area too, shame the Musso is acting up!! I'm still convince they are a pretty good package whatever way you look at it, so I wouldn't be letting a few little issues like these make you even dream about selling - and you've got a few 4WD enhancing mods done too, don't you??

Anyhow, I sent you a PM with a couple of ph numbers, but either will get thru to both eventually. I'm not sure who's moved in with who, but we all live in one biiig house now (not your sort of big house!!) & wouldn't mind catching up with you'n yours at some stage - and the other Musso isn't all that far away either! ;) Give us a call! ;)

Hi everyone! I just came into posession of my Mum's 05 diesel Musso, and I am unexpectedly loving it. I am experiencing problem 1, is that the same diagnosis and fix for my diesel as your petrol?

Thanks for the tips.

vacuum hubs not engaging - played around for a bit, turned out a gasket was leaking somewhere in the hub. solution replace with manual hubs

Clutch making noise - degraded thrust bearing, replace clutch and thrust bearing. Also looking at spigot bearing replacement but cannot find one and am unsure if the mussos flywheel uses one now?

If it's the 3.2 maybe a timing cover leak like mine, it's what I call my Landrover weep :lol: & yes I used to have one. I've been told up to 2000 to fix, so for the moment it stays as it doesn't use much that's noticeable, except for the driveway LOL
This is a reasonably common problem with these motors I've been told same as a small head gasket leak at front of motor on drivers side.
