Boxster loosing coolant fluid


Recommended Posts

I have a '99 2.5L (65K miles) and is my daily driving car. I live in Florida and the summer weather is around 95 degree. At 75mph, the radiator temp. was normal but raised I slowed down or in traffics. The radiators' fans switched on automatically when the needle reached the right edge of the 0 of the 180. The radiators' fans seem to function properly but the coolant level dropped and I have to refill it every other week. Is my water pump going bad? Does anyone has this problem? Please help!

Sounds like you may be the next victim of the ever sturdy (not) coolant expansion tank cracking. Almost everybody has to get it replaced sooner or later. Do a search and you will find many stories about it.

Yep, been there; done that. BTW, in my case, the leak was on the engine side of the tank where it goes thru the wall so when I pulled the carpet back in thre trunk, everything looked OK, but alias (later) when I looked in the engine area....a new tank was needed.

Yep. I just went through it too. :cursing:

Hope it's all better soon. :thumbup:

Same here, no coolant in trunk, but new tank solved the coolant appearing on the ground.

aak5454,

I went thru the same thing. There wasn't a single drop in my drunk so I was assuming it was okay. Until yesterday, I had the rear on ramps to replace the spoilers (underbody air scoops), the coolant dripped right in the front of the right rear wheel.

Do you know the part # for the tank and tool used to replace the tank? My Boxster is '99. Thanks.
