'02 Mustang Overheats/Shudders

Hi Guys - My 2002 Mustang has been overheating and shuddering. There is plenty of oil in the crankcase and plenty of coolant in the radiator. There is no fluid leakage. The car does not stall even when the shuddering is severe and when the car overheats into the red zone. Any ideas on what's wrong with my Mustang? Thanks!

Your thermostat may be bad. (not opening). Your water pump could be bad. If it is like most newer vehicles it may need to be bled. Air taken out of the cooling system.

Not sure about the shuddering.

Be carefull about the overheating, it can warp the head, then you have really big engine issues.

v6 or GT?
