2000 GT, leak?

**Lawenforcer** · 07-30-2016

Well picked up a 2000 Grand Prix GT for another project car and going to start fixing it. First thing is first. Have a leak. Appears to be from the hose coming off the lower radiator. I tried to upload a pic but apparently it won't work on my phone. Anyway, is there anything else around that could leak? Like something under it that I am not seeing from the top that could be leaking? Or should I simply take the house off and ensure it is good and on well. It is leaking pretty bad....sorry I couldn't get the pic to upload.

Thanks ahead of time. This will be one of many questions I am sure to have as I start working on this car....

Could be the hose or the plastic side tank is cracked, hard to say.

Are you talking about the plastic over flow tank?

The radiator has plastic side tanks, those can crack and leak too.

My 2000 GT had a radiator leak about 3 years ago. There was a crack on the lower left side (driver's side) right at the bottom near the plastic drain plug and it drove me crazy for a while because it was very hard to actually see. I put some rat turds in it (Bars Leaks pellets) until I could replace the radiator. If you've got the original radiator in it then its 16 years old and they usually don't last anywhere near that long. I'm on my 3rd one. If you can, make sure you flush the heck out of the cooling system when you change that radiator. No telling what all is in there. Be careful when flushing the heater core though. A lot of guys have put too much water pressure in the heater hoses and end up busting those old seals and creating a puddle on their floorboard.
