1994 pontiac grand prix leaking water

This could be a freeze plug or the water pump has failed,

its possible that the engine is burning the coolant which would not show either by causing the oil to turn a milky color or leave a puddle were you parked. it may be just a small problem at the moment not causing the car to overheat. have the head gaskets checked for damage with a head gasket test. it could also be a possible intake gasket leak causing the coolant to be burnt but not leak into the engine oil. just somethings to check out.

check the plastic cover below windshield..where wipers are at.. theres a seal that leaks water under there and runs down fire wall to the floor.had that problem before myself

You should look under the car after it sits a while and see if there is antifreeze on the ground. If so try to see where it could be leaking under the hood directly over the puddle. You could have a leaking water pump. If so there would be dampness under the right side of engine compartment. Also check the radiator hoses at front of car.

If you look on the firewall on the passenger side there should be a drain hose for the A/C under the evaporator, these can get clogged over time and cause water to puddle on the floorboard. Just take a straightened out clothes hanger and push it up into the drain hose breaking up any blockage in there.


To replace the blower motor, take out carpet under glove box. look under glove box. there should be three screws to take out and then just pull out the old blower motor.

If you see any antifreeze, you are losing it and it will be costly (or fatal) if you don't determine where it is coming from-until you find it, make certain you fill the overflow when the car is COLD to the cold fill line-do it everyday, until you can locate the leak.

You need to pressure test the cooling system and then inspect for the source of the leak. If you are not a DIY, take it to a shop.

If leaking coolant under dash on passenger side floor broad it's your heater core. Call's for 2.8 labor flat time to remove heater core, in some case's you'll have to recover, evacuate and recharge your A/C system to remove your heater core.Sit under dash on passenger side.

could be that when it rains or is wet out that water is leaking into your car under the hood under the vent by the windshield wipers on the passenger side and instead of being filtered out its going into the car on the passenger side floor. (check to see if this is wet after a heavy rainfall) and causing a short and rusting it out. this happened with my 2002 grand prix just this year. I got a water resistor for like $3.50 from a local pontiac dealership/parts store and put it in. Its easy to install and it poured out today and my car didnt leak at all.

yea on bottom rt of ur windshield is what is called the cowl black plastic piece arond the bottom of ur windshield underthat should be weather stripping that may have come off
