    Can't see your car from here...you need to get under there and get an eye on the leak...can't fix it 'till you know what you need to fix!

If you can get acces to coolant system pressurizing kit, pressurize the system with engine cold and look for leaks. The area you are describing is a cramped on on this car and the cooling system plumbing is a bit complex. You may have to raise and support the front of you car to get underneath to get a good look at the heater hoses and crossover piping. Down under the alternator is also a small bypass hose that is difficult to check. Putting pressure on the system should point you in the right place though.

94 pontiac sunbird le 2.0 4cyl leaking coolant


If you are able to lift the vehicle safely onto jack stands, you may be able to get under. With the coolant topped off, and using a flash light, you may be able to determine where the hose goes. Most likely the hose clamp rusted and broke off.
You can also pressure test the coolant system which will tell you where the coolant is leaking from

Pontiac sunbird 1993 using excess coolent, no visual sign of exterior leaking


check your oil. If it is a mliky colour - or is more full than it should be - you may have a cracked block, leaking head gasket ? If so a leak down test will give you an answer. A rad pressure test and/or a compression test would also help find a potetial problem at this point.

Pontiac sunbird 1993 2.0l that has a anti freeze leak from the hose at the bottom of the engine ,the one closest to the fire wall it is on the right side


This could be from the hose that goes from your engine to your heater. I don't know the layout of the sunbird but if you are sure that it is antifreeze that's what it should be. You'll need to get another hose and replace the bad one. Good luck!

Coolant leak close to firewall from 90 degree rubber elbow. 93 pontiac 2.3 liter. It looks like there is a hose missing. Is this an overflow or am I missing a hose? If I am where does it lead?


hoses at the firewall connect the heater core inside the car to the engines coolant system.there are 2 heater hoses.the hose may have deteriorated or if the90* elbow has a clamp at the firewall end and is loose,the inlet tube of the heater core may be broken.use a flashlight for closer inspection.rapid coolant loss will result either way.

My 1991 pontiac sunbird is leaking antifreeze. It


Age of vehicle determines that you get a replacement hose and clips first. Drain down the Coolant into a container, replace the hose, and refill, remembering you are going to loose coolant by spillage on the drain down.

Coolent leak on fire wall in engine compartment on pasnger side


Hi , if you lift up your passenger side floor carpet and check underneath if there any coolant. If it`s dry you know the leak is in the engine bay ,if it`s wet could be either inside or outside of the firewall. In the engine bay check the hose clamps on both side of the hose if you can tight them or if one a those spring clamps try to reposition them. If you have hose clamp right at the firewall then you can easily change the hoses otherwise you have to access it from under or worst case behind the dash. Hope that helps.

Water/coolent leaking from behind the timing cover


Water pump is on the left side of the timing belt in the cover and spins on an O-ring to adjust the belt. Their is a coolant pipe to the the thermostat housing behind the timing covers backing plate also. Be sure to replace the timing belt with the tensioner/ oil seals along with the water pump. Remove the timing covers back plate and you will find two bolt to the pipe as mentioned. It has a large o-ring behind it. Have fun with this one. From: Ronnie Wrench

I have a 1994 Sunbird V6 that is Leaking Coolant from an Elbow coming out from the Firewall. How do I stop this?


Aside from disconnecting your heater hoses, the only fix is to replace the "heater core". The "heat" function of your climate control system relies on heated engine coolant to work. The small elbow that you describe, is most likely the condensate drain. The "heater core" and the "evaporator core(for the a/c)", are located beneath the dash assembly in an enclosed housing. The "heater core" should be serviceable without removing the complete housing as with some vehicles. I hope this helps
