Boxster 2.5 Is Leaking Water After Engine Is Turned Off...

[autoconnoisseur]

I had a radiator leak and changed the radiator on my MY97 Boxster. Now when I started the car and let it run for a few minutes and then turned it off I could see that water was coming from the engine somewhere around the passengers side rear tire. Has anyone ever experienced this before? Also, I accidentally put too much water in the system when I refilled the system. Could this have caused the problem?

Could be overflow - or could be a cracked coolant tank.

Check the carpet in the rear trunk - if it's wet then you likely have a cracked tank.

Were you running with the cap on or off? Did you burp the coolant system?

You need to purge all of the air from the system, otherwise a pocket of air expanding with heat will dump most of the coolant again.

You can find my DIY instructions, here:

Happy Boxstering,

Thanks for the advices! So the car can dump water by itself if there is air in the system?

Exactly!

I had a similar problem with my 98 2.5, the water was running down the overflow and all over the exhaust manifold. It took me forever to work out where it was coming from, what with the limited access and visibility in the engine bay. Anyway, I replaced the coolant bottle cap (for the latest version) and also the pressure relief valve and problem solved. Parts cost about £30 (GBP) from my local OPC. Hope this helps. Dave.
