Coolant Leak

Post by Clipper » Mon Feb 12, 2018 6:32 pm

I have a coolant leak a little bit driver side of center near the firewall. It has left a small puddle of coolant the last two times I left it to idle.

Anybody have an idea of the culprit?

Sorry for the weird perspective.

Thanks in advance.

This is looking from the driver side wheel well look towards the passenger side.

Could be dripping down from the PCV tube coolant connection. It's a bit of a pain to get to and see without removing a few things.

Hmm...

- If not already replaced, I don't know how your turbo coolant hoses didn't burst yet at 23 years old...

Agreed, turbo coolant lines. And actually plenty of them make it this many years, the relevant measure is miles not years, but they do probably look like mush. I'd figure it out and fix it before driving much if at all.

The cars built prior to '99 do not have that coolant line.

1. Turbo pressure.
2. Heater supply.
3. Heater return.
4. Lower radiator.

You'll need to pull the intake and feel around.

If you have to replace a heater hose, get and replace the firewall junction as well. It will likely break when you unplug the quick disconnect (23 year old plastic).

I'm going to guess turbo coolant hoses.
