i was driving in the interstate and about after 45 minutes of driving goin about 80 mph, i notice my temp guage unsually higher then normal. i put it in nuetral and it went back down to normal, but if round 80 or past the temp goes way up. if driving normal (40) then its normal. what could this be?

 

could be a lot of things. did you check your cooling system for any leaks?

is the car puffing white smoke?

 

yes i have plenty of coolant so i dont think there is any leaks. and i dont think there is smoke from the exhaust but i stopped at a gas station and it started smoking. smoke was coming from somewhere under the IM

 

and after the smoke i drove another hour and 45 minutes back to town and there was no more smoke

 

sounds like a leak from a hose under the i/m. check your coolant level again. i bet its low

 

ok will do

 

check you coolent for oil it that make it do that.!!
i had 93 lx it had a pin hole in head gasket and it got oil in coolent then after a little after a week the hole got bigger. i had to change head gaskets..

 

did not find any leaks

 

coolant does seem a bit darker then usual. i think that might be it.

 

ya dran all coolent and see if it turn dark .. it should turn dark after driving it for 15min

if you see like little dot of oil in it you are going to need new head gasket

 

ok thanks

 

happy to help

ps let me know if it works
