Just put my 2003 911 C2 on the road for the summer and after the first drive I’ve developed a leak. The fluid is coming from the back of the engine.(driver side) The colour of the fluid is reddish, but what’s throwing me off is the fluid wasn’t hot. Any help would be much appreciated. US car

 

Rad fluid from a cracked overflow tank. Common issue

 

When I said back of the engine, I meant where it meets up with the transmission. Coolant tank leak?

 

Automatic or Manual trans ?

 

Manual transmission

 

in that case the coolant line going to if from the aos.

 

To be clear this car is left hand drive?

 

Sorry. It’s a US car. So left side of engine, where it meets the tranny

 

Then is a coolant line to the AOS, or the AOS itself. My AOS broke open and leaked coolant, left side of engine near the transmission. I replaced the AOS, that fixed it.
