New hose's with coil wire in bottom hose, new water pump, had three different new thermostats, (2-194deg-stock setting and even 1-185deg) now running with nothing. New head gasket and NO it's not put in wrong on this engine, can only fit one way. And there was nothing wrong with the old one anyway. Head has been hot bathed, valves and sets resurfaced, and head shaved.007. The engine is malti-port injected, intake has been cleaned, new EGR system parts. Fan is installed correct. Is not burning coolant, engine only uses 1 liter of oil in 6000klm driving emty, and 1liter in three tanks of fuel when pulling 17ft trailer loaded. No coolant in oil. Never has been. Engine has never been rebuilt, this problem started at 286,000km and the truck now has 458,000 on it. And only one owner, me. About the engine running lean, not sure about that, being fuel injected, but I do have another truck, with the same engine, but a year newer, with only 292,000km on it, picked up 100$ after it hit a power pole, thinking of taking the (chip) out of that one and puting it in my truck. But my truck has always been a turn key runner, one crank and it starts. I also have put in new gear to gear timing set, and the timing is set at spec. About the belt slipping, only one belt for all with tensioner, and yes I did replace that some time ago. And ther is NO A/C.
3inch exhaust-front to back, high flow muffler, all good.[/Quote:2fc7e0516c]
Wrong signal from O2 sensors at closed loop/partial clogged injectors and low fuel pressure will make it run lean.[/Quote:2fc7e0516c]
O2 sensors? There is three of them, will need to pay for that one to be diagnostic coded, but do have a home hand held one, should give that a try again, injectors have been replaced, new fuel pumps last fall( first time they messed up after 450,000km, not bad don't you think?
