Question about 2006 Pontiac Grand Prix
Smells inside car
Posted by Anonymous on
Is there coolant leaking inside the car? Check the floor under the passenger side dashboard. If the carpet is wet your heater core is leaking.
If the floor is dry check the coolant elbows going from the block into the automatic belt tensioner. That's inside the engine compartment. They are notorious for leaking. You may not be able to see the leak because it drips onto the block and evaporates. That's what the smell may be.
Search google images for "3800 series 3 coolant elbow" to see the part I am talking about.
The only way to find a coolant leak is to pressurize the cooling system. You can rent a coolant pressure tester from an auto supply store. Pressurize the system and look for leaks. You may have a leaking water pump.
The elbows can be purchased from the dealer. The water pump you can get from an auto supplier. Might as well change the thermostat while you are doing the other repair. Drain the cooling system and refill with fresh dex coolant.
Make sure you bleed all of the air out of the system or the car will overheat.

Inside the glove box on the passenger side you will see an opening. Use a light and you will see that it says "pull here", remove the plastic and the fuses are right behind it.

Pontiac stopped installing the fuel filter on the rail in 2006. The 2004-2005 models had a fuel filter on the driver's side under the rear passenger seat area clipped to the frame. 2006 beyond the fuel filter is part of the fuel pump unit inside the tank.
