Car overheated a cpl times when pushing her hard..... noticed the fans will not come on without turning on the AC.... noticed the top water hose going to the radiator is super hot but the bottom hose is cold.
How can tell if the water pump stopped pumping?...
Noticed temperature goes to the 205... 210...range.. at times
The fans both work if the AC is switched on but not otherwise.... I bypassed the fans at the temp switch.. .they both came on... thought it was the switch... changed the switch .... still no fans working after changing out the switch ..
then I changed the thermostat... still no fans working..
The heater in the cab seems to work fine and I get plenty of heat from there....
There does not appear any flow into the expansion tank when the engine is running...
I am suspecting the water pump failed but not 100% sure ... is there a way to find out for sure if it is pumping or not?
Another 20,000 mi or so to the next TB change.... so maybe it's time to change the whole thing our early?
You thoughts?
tnx
