Air pocket in coolant system or the first sign of blowing head gasket.

===

When the car is completely cool,check the electric fan(s) for smooth rotation.

Clean/check/change the thermo sensor,contact and wire.

===

Excavate air pocket in coolant system / check for head gasket leak

This test will kill two birds with one stone.

===

MAKE SURE THE COOLANT SYSTEM and ENGINE IS COLD!

RAN THIS TEST IN A WELL VENTILATED AREA ONLY!

You will spill some coolant during this air pocket purge test.......BE KIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!

===

Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .

Top of the coolant reserve tank

Let it ran for 10-15 minutes.

Monitor for air pockets escaping from coolant reserve tank.

Small amount of bubbles is OK at 1-5 minute mark

After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.

If you do not see any in rush of bubbles then your thermostat may be partially stuck or rusted badly inside the thermostat hosing.

Give the thermostat host few gentle taps.

If you see larger bubbles surfacing after 15 minutes then should do a hydrocarbon (HC) dye test to test for potential head gasket leak.

Let engine cold down and top off coolant reserve tank.

Start monitor for coolant lost

===

A coolant flush is require every 2 years or 24,000 miles.

I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.

Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.

OVER HEATING ON THE 1995 GRAND AM IS CAUSED BY THE HEATER CORE BECOMING CLOGGED.
WATER WILL NOT FLOW FROM THE BLOCK THROUGH THE THERMOSTAT AND THEN THROUGH THE HEATER CORE IF A CLOG IS PRESENT.
ONE WAY TO CHECK IS TO REMOVE THERMOSTAT AND RUN CAR. THERE SHOULD BE NO OVERHEATING
IF THIS WORKS, REPLACE THERMOSTAT AND HEATER CORE
THE ONLY ISSUE THAT MAY ARISE IS IF THE RADIATOR BLOWS A SEAM DUE TO THE EXCESS HEAT WHEN OVERHEATING

Get som premix antifreeze and add a bottle of redline water wetter (available at most autoparts stores) what ever you do dont run just water in your car! you may think you are saving money but antifreeze also has corrosion inhibitors and special lubericants for your watter pump. without it the dissimilar metals in your engine will corode fast turning the water into a rusty mud that will plug up your radiator and with out the lube your waterpump seals will fail much sooner. I only run antifreeze mixed with didstilled water in my cars plus the redline because it stays hot down here in south texas

How do i change the rear turn signal on a 2005 pontiac gran prix


you should be able to access the bulbs from inside the trunk.
Pull the carpet back to expose the back side of the light cluster.
You will not have to remove the entire plastic lens , just the little bulb inside.

Temp gage is registering over 1/2 after replacing the thermostat


Sounds like you have an air pocket trapped inside the cooling system. There are 2 bleeder screws on this car if i remember right, 1 is on the t-stat housing or near by and the other is close to where the other rad. hose connects to the engine, usually a little brass screw.
