What caused this?
I took my 99 in for installation of PSS9's at a reputable establishment. When I picked it up, the owner (super guy, very professional) told me that he didn't have a chance to test drive it but that if I noticed anything to bring it right back. I haven't had a chance to drive it much, but today going over RR tracks, I heard a clunking sound in the right rear. I also noticed that the engine temp is edging over the "0" when it used to just sit right between the 8 and the 0, and I catch a whiff of hot coolant. The car has never run over the "0" before, and the weather is cooling off dramatically, so it's not ambient temps causing it.
Can anyone tell me if in the process of putting on a set of PSS9's.... is there something in that vicinity that a person could knock loose that might cause that hot coolant smell? I recently replaced the old style blue coolant cap with the newer black one...so it's not the cap. It may just be coincidence and a coolant tank going bad....but I've got to ask anyway.

Check you coolant expansion tank for leaks. The coolant expansion tank provides an buffer for the coolant to 'overflow' to when the cooling system is running. Replace yours with a new one if it is cracked or if there is corrosion inside. I had the same problems without the clunking, changed the expansioin tank and temp looked good. Early 996 have a problem with their expansion tanks. A new porsche expansion tank is an upgrade from the old at 250$.

No offense meant to your mechanic but i wouldn't take my car to someone for service if they told me I had to test drive it myself and let them know if I had any problems.

The tanks in those cars break often. I know that there have been 3 updates to the tanks by now. I have them in stock. The tank might have broken because of the stiffer spring rates the PSS9 runs. (more vibration) I would check that tank and get it replaced. As far as the clunk could possible be the spring seating itself correctly on the shock. At 1st when you have a car up in the air and then put it back down the spring will not seat in the correct location but if you hit some bumps then the spring shakes and settles. Bring the car to him have them check out the suspension. Worse comes to worse it is nothing and your alright. Should be no charge to have that done.
When you ask if there is anyway someone can hit the tank or cause something to break with coolant while doing the install that is just not possible. Let us know how you make out.

Thanks for the feedback...I'll take it back.....and yes OH997...when I pushed the transmit button, I immediately thought...oh oh...someone is going to jump on that issue of the fact the guy didn't test drive the car. You're right...he should have test driven it....and it's going back for a check and test drive to find the clunk. I don't know enough about the coilovers to say if they just haven't seated themselves...but that's something for the installer to deal with.
It is possible that the stiffer ride could have caused the coolant tank to crack....it's just that the coincidence didn't sit right with me....but I didn't know if during the install of the coilovers....is the coolant tank close enough for someone to break something?

Mine is sometimes between the 8 and the 0, other times right on top of the 0 or a hair higher. I wasn't worried... just figured it was the thermostat doing its thing depending on engine load, a/c on or off, whatever. Am I being too laissez faire?
Thanks, and again, sorry to hijack your thread.

Will a crack in the coolant tank cause the car to run slightly hotter than normal? I've noticed that since I started smelling hot coolant, the car runs a tad bit hotter on the gauge than it did before. Do you think that a leaking tank would cause that?
