yes with out the temp gauge going up. but it was a short trip the truck has 80 k and has never used fluid
I put a half gallon of fluid in the resevoir and I'm letting it run. ther ewere bubles entering the tank right away i am going out to check it again still bubbles with the cap off
Ok first off, the engine warranty on this engine is good until 100,017 miles and the date of 12/06/09. This would be a $100 deductable repair though if needed. The coolnat coming from the overflow while still cold really concerns me as the pressure just should not have been there at that point. I would also recommend allowing for the engine to cool and then properly filling the cooling system to verify that there are no air pockets or anything of this nature. You stated there was no coolant in the container today and that could certainly mean that there is air within the cooling system. Here is how you should be filling this system.
I checked truck after running 10 or so minutes and air was still bubbleing into tank. Top radiator hose was cold as well as the fluid returning to the resevoir. when I cut the engine off an amount of fluid came out of the tank. I will let the engine cool and follow you instructions on fillinn the system. How long does the engine need to run to move the temp gauge to normal operating temperture?
Do you think this is something I should call the dealer about in the morning. I let the engine run10 minutes at idle and another 7 minutes at 1500 rpm and the top radiater hose was still cold as well as the fluid in the resevoir. If the thermostats were not opening would this affect the temps of the top hose
