If it were mine, I'd replace the 28 row cooler with a Carrera cooler with fan. Mine never touches 220 degrees. In 100 degree weather stuck in traffic, the car runs at 200 degrees.

I have a trombone in my 2.7L with a 5 blade - I never get to 100C in Texas heat. Then again, I run my oil in it as well.:D

Its on my list of things to do. Thanks a bunch for the input.

I just drove it around town, I had to register it and make 2 other stops. I watched the temp closely. Its probably 95° outside right now. It was at 190 and went as far north as 195 but never hit 200. This was in regular everyday driving, sitting at lights, city driving.

I ran into my temp problems in Gatlinburg Tenn. I was trying to get to the entrance of the Smokey mountain Park and all the Dollywood traffic was clogging the roads. I sat in stop and go traffic for 7 miles, gave up turned around and went around the park. I was sitting for almost 1 hour. I think this was an extreme but I still did not like what I saw.

I am a bit of a fanatic when it comes to this stuff. I am going to search out a Carrera cooler and have a good shroud made for an electric fan.

As far as oil that I am running, unknown, I just got the car. I was told it had dyno oil in it to break in the new cams. I am switching over to Amsoil 20/50. Hence my question about how to get a complete flush out of it. I guess I'll do a couple of changes over the next 3000 miles to help get it switched over to full synthetic.

I might be able to help you flush out the old oil. We have a flushing oil that you add to the exsisting - takes 1 qt for every 10 in the system. Let it circulate for a few days then drop it out. It is very safe. It doen't contain any acids or solvents. I have used it on my Targa and all my other cars as well as hudreds of different engines including turbo chraged ones. If you would like I can send you some. Just PM me.

BTW - What is the proper procedure when you see another Porsche on the road. I was next to a Boxter yesterday and waved, he looked shocked and waved back.

Today I saw a beautiful 356 Cabrio it was red and perfect. I drove past him slowly pulling into the turn lane. He went by me as he got a green light and wouldn't even look my way. I look like a dork waving. Oh well.

Jim, there is a great thread on this. I will try to find it.
