Customer: I putting coolant in it every other week.

JA: Anything else you want the mechanic to know before I connect you?
Customer: My car is getting stuck in park also.

HI,

Ok, I need to the exact engine size. If you are not sure, post the 17 digit vin number and I can get it from that.

You stated that you are having to add coolant every other week. Are you seeing any coolant leaking onto the ground underneath the engine compartment

There is coolant in the car but it's rusty

HI,

Ok, last question - has the engine cooling fan been checked for it running

Customer: replied 3 months ago.
It's running

HI,

Ok, there is a very common issue on the 3.8L engine which is what is in your GP, which causes overheating and coolant loss without any showing up on the ground underneath it. This is a leaking intake manifold gasket and cracked manifold.

The cooling system needs to be pressure tested and if the pressure drops without any external leak, then the intake manifold and gasket need to be pulled and inspected and replaced if needed. On the low chance it is ok, then the headgasket would need to be replaced. But it is about 90% chance it is the intake.

If the intake and its gasket, it runs around $675 parts and labor to replace it
