Thread: I finally brought my 98 Grand Prix GTP

Pretty sure...depending on the freeze plug...you can do the front ones...but the rear are next to impossible to get to without yanking out the motor.

I lifted up the car and check under it and saw two freeze plugs up inside that had fall out of the block and as well this is where the Dex cool was dripping out. This anyone know? What are the procedures to fixing this problem correctly ? To replacing the freeze plugs. The car is 1998 Grand Prix GTP SC. Thank you for your time and comments DAVE MC

clean the hole in the block,(sand off any rust or grease) they have a tool thats the size of the plug with an extension so you can pound it in with a hammer, or if you have a socket the size of the plug and a extension you can use that too.

ive seen loc tight or maybe some other freeze out plug sealant as well, that you would smear on the new plug and then install it. never used it myself tho, cant hurt though.

loctite, for heat

mine is doing the same thing?i changed oil and etc. today went to put some water in the radiator and wow!~my driveway wound up flooded...but after i finally noticed it.it seems to be coming from directly behind the front manifold.
if it was run hot because of this would it cause the car to start knocking?
