Hi,

Can you see if it is coming from toward the top of the engine or does it seem to be lower? Also, do you have a rear auxiliary heater?

There are a couple of heater pipes for the rear heater that corrode and can leak. You will need to be under the vehicle to see if that is the issue. Also, there are two heater hoses to the front heater core that attach at the firewall. One of the hoses could be leaking. See pic below.

If none of those are leaking, we then need to pressure test the cooling system. You will need a pressure tester, but most parts stores will lend one to you.

Here is a link that explains how it's done:

Let me know what you find and how fast it is leaking.

Take care,

Joe
