I have a friend who bought a used 1995 grand prix it runs good untill the other day. He says he was driving and noticed the temp guage go into the red zone so he stoped and when he checked the antifreeze there was none in it. So he puts some in and takes it to a local shop but the man at the shop says something inside the motor is bad and its going to be expensive but they dont do major internal motor work so they would suggest a place. I asked him if he looked at the oil and antifreeze in the car and he said they were normal looking (didint look like the milkshake mixture from a blown head gasket) and the oil wasent over full or anything jsut antifreeze was a little low. He said the car is not blowing smoke out the tail pipes at all while running. He did say he was not getting good heat out the heater when he was driving it. Im jsut trying to figure out what it could possibly be. Dosent sound like head gasket perhaps heater hose or heater core? Im jsut wondering if the shop is full of bs too. Any ideas of what we should check out when he gets it back would be appreciated.

thanks

thanks ill check that out when he gets it back. Im wondering if the heater core went south and some rust and crap may have traveled through the hoses to some where in the block. I hope not cause i have no idea how to get it out. For some reason he didnt pay good attention to the shop when they told him what was wrong but he remembers him saying something about the pressure in the cooling system. I told my friend to pay better attention next time.

thanks again

more then likely its the intake gasket, im assuming this has a 3100 V6 in it, and not the 3.4 Twin Dual Cam motor, 3100's and 3400's are known for an intake gasket leak, its a garbage design, basically the intake gasket is soft plastic and it is filled with o-rings which actually seal, its good in theory but whe plastic usually breaks, which allows the o-rings to move and leak., my sister has put 6 sets of intake gaskets on her beretta with a 3100, it still runs great @ over 250k miles, but it needs those gaskets every 40k or so
 
If there is no oil and coolant mixture, than the intake gasket and head gasket is out of the picture. The no heat problem was due to no coolant running through the heatercore, since it was empty.

Fill it with coolant. Make sure its not leaking externally. If its not leaking externally. Check and replace the thermostat.

coolant doesn't just disappear. and if the intake gasket is bad, it won't always leak into the oil. I believe with those gaskets it will leak enough so that manifold vacuum will pull coolant into the intake port. fill it with coolant, leave the cap off and start it up. make sure there are no bubbles in the radiator (or resivior if that's where the pressure cap is). If it bubbles, it's the head gaskets. more then likely it's intake gaskets because the 3100 and 3400s are famous for that.

the new felpro gaskets are metal with ruber, so they should last much longer, might want to use those next time
