My f22b2 is overheating in traffic and taco bell's drive thru, i just replaced thermostat, radiator is about one year old and in good shape, has plenty of coolant (50/50), both fans operating properly.... im stuck on this one! Any sugestions on what i should do to stop this overheating?

 

Water pump ,open the cap cold rev the engine you should see it overflow. Air in the system ,the F's have an air bleed next to the thermostat. Leaks, pressurize the system and inspect everything. Rad cap ,thy fall apart over time and will not hold pressure this usually results in a lot of fluid in the overflow reservoir. Crap in front of the rad ,no air flow. Fans spinning backwards ,wires reversed. Head gasket ,look for white smoke out the tail pipe or bubbles in your system. You need to check this stuff in any order go from easiest to hardest.

 

does ur car overheat only when its stopped or at any given time. and how many times has this happened?
