I just bought a 87 mm w/ G63B and when I turn the truck on the temperature guage climbs rather rapidly, within seconds it is peaked.... Do you think that it could be a bhg or something less serious? Any help would be most appreciative..

is it actually getting that hot? feel the hoses top and bottom thats a good start. i dont think a motor can get that hot in a few seconds from being cold.

No it doesn't feel hot on the upper or lower hose... do you think it could be a sensor?? Or maybe the HG??

Definitely think you just need to change out the sensor, I think its almost impossible for it to get up to temp so quick.

Cool thanks, I do however notice maybe just condensation burning off upon startup out of the exhaust ... but I will check the sensor first...

as in smoke, if so what color? or what exactly do you mean by condensation burning off upon startup

It looks a little white to me.... what I meant by condensation do you know what water looks like when it boils.... the evaperation of water..

I agree w/changing the sensor, but I'd also take a look at the oil, for a milky look, and inside the oil cap. A compression check wouldn't be a bad idea.

i know this sounds stupid but is there water in the radiator?...sometimes the hoses will be cooler to the touch if your very low and not moving water....

I checked it it has water in it.... I got all parts on order, head gasket, temperature sensor, head bolts, thermostat, radiator cap, oil, oil filter, coolant.. I think i will just tear into it and see if it fixes the problem... Thanks for all the help, I will keep you guys posted on the progress.

K so I put all the new parts on, and now I have the timing almost perfect just has some hesitation, and makes that popping back fire sound.. What do I need to set the timing to?
