Chev 6.2/6.5L Diesel Engine Tips and Tricks

Hi.
Does anyone know where I can download an engine manual for my chev v8 diesel? It's in an 80 series so I only need the engine section, as all the rest of the car is still genuine Toyota.

Thanks

Mike.

Mike,

I have been looking like crazy on the net. Everything keeps pointing me to the Haynes Chev service manual which covers the whole chev range petrol and diesel so nothing specifically for the donk we have. That retails for about $40.

Keeping my eyes pinned....

I've got one here from when we had a 6.5 Chev powered GQ in the family. It is one of the Haynes Techbook series (Haynes Automotive Repair Manual Series) - title 'Diesel Engine Repair Manual' No 10330 (17336) and covers GM (5.7,6.2 and 6.5 litres) and Ford (6.9, and 7.3 litre) engines. Published by the Haynes Publishing Group in England, and Haynes North America, Inc in the USA. ISBN 1 56392 188 X
Any good technical bookshop should be able to point you in the right direction.

6. 5 Chev diesel manuals

The manual you are after is often on Ebay , they are ex US army in book form, about $15usd . They are very comprehensive. I have the 6.2 manual . The engines are almost identical, all parts inter fit with the exception of the rear main oil seal ,and early model 6.2 head gaskets. I have spent 10 years repearing ,rebuilding and fitting these engines to various vehicles, any questions regarding this fine GM product, I would be happy to answer on the forum or by email .

6.2 / 6.5 diesel Overheat

Hi to Kingchevy . wow man, you have touched on one of the favorite chevy questions.:mad: I chased the problem for 8 years,for my own, and several other clients . For all overheating problems there is rarely one answer alone, to establish the cause . Firstly on these engines there is 2 types of belt drives, the early 6.2s and 6.5s had V belts , the later ones had Serpentine belts. If your engine had a serpentine belt ,and you now have fitted V belts, the waterpump will be rotating in the wrong direction. Now you'r going to ask me how do I tell . When I work out how to add pics, I will post them . Ok next thing .You have to start with the basics . Does the fan lock up PROPERLY ,can you hear it roaring , does the thermostat work properly and what type is it & what temp is it.(( Are you positive the gauge is accurate.)) Is there a coil spring in the bottom hose. Air flow into radiator.Is there any restrictors in the system. What width belts. How many belts drive it. What kind of fan are you using,(do not use electric fans). What kind of pulleys are on it . Who did your conversion ?? and engine build. Now we get to the good part.. What type of radiator is it . Std Toyota ? alum or copper.Or one of these so called you beut ones. What side, pass, or driver, does the top rad hose go into. Run the motor till it gets to normal temp, take the top off the overflow bottle, put the rubber tube into a half full coke bottle of water, raise the revs to about 1500 and check to see if there is any bubbles blowing from the tube , which would indicate a blown head gasket.... From now on it gets interesting. Let me know all the answers to the questions, before we get to the nitty gritty.. There is an answerI will tell you when all else fails:D...... Les

Thanks Les I'll look on eBay.

Can you tell me where the Tacho getis it signal from on the 6.5L? Mine seems to stick when I first start the motor. I know it's not the head unit, because if I tap it the needle jumps. After the motor is running for a few minutes the tacho will then start working properly. BTW it's in an 1994 80 Series.

Tacho sender to gauge

Hi Mike, it can be sent from 4 places ,1- the oil pump drive at rear of the engine in the middle of the V. 2 Ring gear teeth from a magnetic sensor in bell housing . 3 from an after market kit with a sensor mounted on the timing cover aimed at a pin placed in the harmonic balancer. 4 6.5s Had a sensor with 2 wires that fit ito a hole in the left side near the bottom of the timing cover..

Engine improvements

Good stuff Mike . Some of the engineering shops in USA do some remarkable things with these engines. You will never run out of parts for them , as AMG Hummer bought the entire machinery from GM and now fully produce the engines, with some very good modifications to their known problems . Les

V8 Chevy diesel overheat problems..

This is to identify the two different types of water pumps fitted to V8 Chev diesels
The left one is for Vbelt drives , the right one is for Sepentine belt drives .Note the difference of the top section of the pumps . It can easily be seen on your engine, just below the oil filler tube where it goes into the engine.. Serpentine pumps run in anticlockwise direction,as the belt drives the pump from the outside of the belt. Note -- Dealers will be aware of this on their instalations, People who purchase their engines else where , may not be aware of the need to change the pumps, if fitting V belt pulleys..Les
