2000 grand prix overheating
While driving on the highway my 3800
v6 2000 grand prix started making a
noise under the hood every time I
accelerated. When let off the gas it
stopped. Started to overheat and I got
it off the highway and it died. Waited
for it to cool off and turned it on it
stayed hot (240) but didn't overheat or
make the noise so I made my way
home. What was the noise and why is
it over heating? Please help. Water
pump, thermostat, reservoir tank and
radiator cap have all been changed.
Is it running dex-cool? Check near the power steering pump and the rest of the engine cause u may have a blown head gasket.
It isn't running Dex cool. I was wrong the radiator had been changed not the water pump. Could it possibly be the water pump?
No, its not the water pump. When water pumps fail they start to leak or make noise, but they always keep pumping. I'm presuming you've checked your coolant level. If the coolant is gone the plastic elbow that takes coolant to the heater may have failed. After that I'd suggest having your exhaust system checked. A plugged catalytic converter can sometimes exhibit those type of symptoms.
