heater cord not working

[nick k.]

Hello all, thanks for looking at my post. I was just curious if this could possibly happen. Well for about a week now everytime i plug in the heater cord for my car it does not keep my coolant warm. Then just last friday i notice my coolant light coming on. I decided to get my coolant changed , i changed it even had it pressure tested with no problems. That night i plug in my car once again and in the morning the car was still cold like i didnt even plug it in. I just checked out were the heater cord leads to and i noticed coolant around the area . Im not sure if i pulled on the cord and maybe made a small hole or dislodged it were coolant can leak out or if one of my gaskets are gone and so is the heater cord. Im thinking that the heater cord is not seated properly in which case is causing the leak. Any help with this problem would be appreciated.
Also i check the coolant level and its still full, could the excess coolant be from when i had a pressure check done when i changed my coolant??

I'm sorry to say that I'm not familiar with what it is you're talking about. I am aquainted with block heaters, which keep the engine block and motor oil warm, for easy start-up, but I wasn't aware that a "coolant heater" was available - although I'd sooner have the oil warm than the antifreeze.

There are a few companies that make a small heater that installs on one of the radiator hoses. I had one of the these many moons ago. They work really nice because the heat the coolant, there by heating the block. Since oil really doesn't freeze easily, it is a better to keep the coolant from freezing, this keep you from over heating the engine while it waits for the coolant in the radiator to thaw.

For your problem, would just replace the unit that heats it up the coolant. That way you don't have to worry about it leaking again in the future.

yea, alot of coolant heaters are mounted on the lower radiator hose, which does keep the coolant from freezing, but it's also restrictive. My advice is to get rid of the coolant heater and get a block heater.

nick Hey where ic the coolant heater? I have the same car.

Where can you find the location of the coolant heater on a 1997 pontiac grand am gt 3100?

Also, where are some good sites for pontiacs?

The only block heater that I have ever had was mounted in a freeze plug. It came from the factory that way. That heated the coolant. It also rusted out causing a leak. I suspect the same has happened here.

JCWhitney sells several sizes of heaters that can be installed. Some are flat plates that go on the oil pan, immersion heaters for coolant hoses and one that goes down the dip stick tube.
