Is the thermostat ailing my '00 996

[Derek S]

I'm not sure if I'm id'g the problem correctly but at the heart of issue is not having Autotechnik in Pennington, NJ or an independent shop in S.E. PA or Central NJ.

A couple months ago I noticed a trail of antifreeze on my garage floor after a drive. Since then the run off of antifreeze has reoccurred pretty consistantly. Any thoughts on a sticking thermostat or bad expansion tank? I've seen the temp light once or twice before in '07 and top it a/f that looked low. My 996 has 27K is generally to spec on maintenance and care.

Any helpful thoughts would be appreciated?

Can you explain where precisely the antifreeze on the floor is situated, left rear behind the wheel, rear - middle, etc.

Most likely a cracked coolant tank. The water pump sometimes leaks too. Those are the first two I would check.

Left Rear, yes-behind the wheel. Originates above the left tail pipe. I haven't poked up in there to see it more closely. Lately, after reaching operating temp I smell the lovely fragance of burned antifreeze. Seems Loren was leaning towards the coolant tank or W/P. What do you think? Would a closer inspection of the inlet hoses to the tank and wipe down to spot the run off be first steps? If it's the W/P then I guess it's a matter of replacing gaskets and hoses, thermostat, etc., while it's off.

Thanks for the quick reply. RFM seems to be heading in the same direction. The leak seems to originate higher on the engine, as you suggest and then finds it's way over the tail pipe and down. I'll inspect the area more closely and give it a good wipe down to clean off any residue , drive and look for new run off.

Time to order a coolant tank (and cap if your cap does not end in 01).

Sunset Imports (Porsche Parts at Dealer Cost) has both on sale - Porsche Parts at Dealer Cost

$274 for the tank and $12 for the cap.

If you decide to tackle this yourself - there is a DIY here.

Hi Loren, Thanks again. I hope that's all there is. I've bought from Sunset before and they were good. The link is very helpful, pics worth a 1K words and makes the project look do-able for me.
