When my car sits for more than a few days there is a yellow fluid that drips on the garage floor under the motor (sorry not good at posting pics to Rennlist). It doesn't appear to be motor oil though I could be wrong. Oil level doesn't seem to fluctuate on dipstick. Have not taken the time to jack the back of the car up to crawl underneath it to check for wet spots. Wondering if anyone knows of a common leak of a yellow-ish fluid.

Thanks (again) ahead of time.

 

May be the coolant. Check the reservoir to see if the coolant in it is the same color as what's on your floor.

Does it evaporate? If so, you know it's not oil.

 

Crawled under my car. It's coolant. Coming from H20 pump housing (good call 5CHN3LL). Any chance it's just the gasket or do I likely need H20 pump too? If I elect to replace the pump, I've seen $250 - $350 units at ECS & $110 units on Ebay (including the gasket). Is this a part I should take a chance on?

 

If it's the original pump, it's due for replacement (as preventive) anyway. I think the stock pump from Sunset Porsche is no more than $300.

 

IMHO, NO! FWIW, I went with OEM when I had my tank replaced (along with cap, WP, belt, hoses/lines and t-stat).

 

If it's leaking or the pulley is wobbly, definitely replace the pump before it fails. This is the voice of experience talking.

 

FWIW, except for IMS bearings, I strongly favor OEM parts for "mission critical" components, and water pumps certainly fit that category.

I don't think I've ever heard a Porsche owner say, "Gee, I wish I had installed a cheaper, after market part."

Also, if your fluid is original, it's also a good time to flush the coolant and change it to the newer OE pink coolant.

 

Thanks guys. Got a new H20 pump on order.
