Hi,

I've been very busy this weekend. I've got the car in full service mode

I removed plug as John suggested. I pushed a heated screwdriver in the plug and was able to get it out of the radiator. (thx for the hint John ! ) Unfortunately a part was left behind in the back of the radiator. I think it is kind of a plastic retaining clip... more on that later.

I also removed intercooler because he was completely clogged and some oil inside the tubes. This one needs some serious cleaning after 190.000 miles of usage.
I also noticed a broken wire. The wire is attached to the tunnel that guides air to the intercooler. it leads inside the engine bay and I found it broken right behind the air filter box. any ideas on that???? (see pics)
I think proper cleaning of the intercooler will revive some hp. I will have it cleaned together with my radiator.

Car is now ready for some engine bay cleaning and replacement of all belts.
any other sugestions what I should do while I'm at that stage?

bye

Just had a quote from radiator/intercooler specialist... Intercooler seems to be too far gone... it's leaking air... It could be fixed but I was looking at a price of about £70 to clean and repair. Bought a second hand on ebay in uk for £25 of a carbreaker

They promise it will be checked for good function before shipping and is guaranteed... It looks good, hope it functions as good as it looks...

Since very sorry state of my intercooler guess is that turbo must have been leaking an excesive amount of oil.I see a fair amount of oil inside the tubes also...I will dismantle the whole unit this weekend. I will install a new turbo cartridge while it is out anyway. Turbo has done almost 200'000mls so it won't hurt I think...

Hi,

Thanks for a interesting thread.

Not all of us drive Quattros

and I will soon have to do similar work on my 260,000 km 1993 Avant.

I would be very interested to see what you have done/found.
