how would i fix a coolant leak that has?

Question

i have a 95 chevy blazer that i recently changed the radiator but not the cap i used my old cap from my old radiator. i think that might be my problem but im not too sure. this morning i found some coolant that was leaking into the inside of my truck what can cause this to happen? and how could i fix the problem?

Answer 1

You have a leaking heater core or a leaking heater hose or connection. You may have to remove some of the internal dash panel to gain access. I would check the hoses first to make sure they are OK, but while you are in there, change the hoses anyway on one this old. Good luck.

Answer 2

First you need to find the source of the problem. Run the engine, goose the throttle on the throttle body and see if you can find the source of the drips.

I'd be looking at radiator hoses or the cap since you said you just replaced the radiator. Or, you could automatically eliminate the cap as a problem if you go ahead and replace it.

Edit: Oops, "inside" as in the cabin or "inside" as in the engine bay? If its the cabin then its the heater core. Not too expensive but it can be hard to replace depending on how the dash is designed.

Answer 3

Yup....Heater core.
It's like a little radiator in your heater box.
They can be quite a challenge to change

Answer 4

That would be your heater core.... you need to get a new one. It is leaking inside into your vehicle.

Answer 5

Check your radiator hoses might need to grip it tighter, and try McGyver method by using egg white...
