Coolant leak by passenger foglight

[csr ma71]

There's a fat puddle of coolant below my passenger's side foglight. What can be leaking around there? It's not the radiator, lower radiator hose, thermostat housing, two coolant hoses to turbo. What else am I missing? I think I felt some coolant where the cps meets the head, but I'm not sure if any coolant lines run there.

You're not going to find this much help but I'm always puzzled why some people think it's easier for those on the internet to find leaks than it is for someone who is right there with the car...

I have the same damn problem but I haven't really looked at what it is yet

Closest thing there is the lower radiator hose...

Have you checked to see if your washer bottle lines are leaking?

 

[csr ma71]

It is definitely a green puddle right by the foglight.

My 90 degree hose was pissing a little bit (and not all the time) strait at the fan. Then was slinged around making it looked like it was comming out from everywhere.

Coolant hardpipes that mount to the back of the thermostat housing?

I was also gonna say washer bottle leak, so double check it too. Or the coolant is craping down around and across from somewhere else.

1. Buy UV dye kit
2. Add dye to coolant
3. Use flashlight included with kit to find leak
4. Fix leak.

All without guessing or replacing something that doesn't need to be replaced.

Probably the best mode of action, I also was going to mention thermostat housing/hardpipes dripping.

My suggestion take it to a local shop usually they will do a coolant pressure test for $20, thats what the price we charged at firestone and at goodyear.

If you have a blacklight (UV light) handy, you can cut open a glowstick and dump the UV liquid in the radiator. Same thing, and most people have the stuff laying around. Just be sure to flush the coolant system afterwards with either method.

Found another possible cause of the leak, not sure how it would migrate to the front of the car however.

Leak stopped for two months after the heater control valve was replaced. Now it has returned in the same area.

Try checking for wetness under and behind the thermostat housing down by the power steering pump. I had a small leak from the hose there that collected in about the same area but definitely not as much as what you're seeing.
