tranny please???
OK, I know alot of people that have the 03 e/clk (500) have the trans problem with valeo radiator and some with the 04 model.
So0o my qusetion for you guys is that, i have a 05 clk500 with valeo,
do i need to replace it??? or is this a new updated one ?
If i do have to replace it, i know the behr is what every one was getting, but i cant fine any. BUT i found this http://www.importautoparts.com/feed/...s/clk500/2005/ do you guys think it would be any good???
thanks for all the info and help guys!!!!
150-200 is better then 6000-7000
If you have the valeo radiator you should test your tranny oli asap.
It starts to leak sooner or later.
Then you have to change the radiator, transmission and turbine. It's about 8000usd.
I know, i just did it




I'll probably end up doing what you do 05clk500Art, so let us know where you find the Behr radiator and how much it cost to install. By the way, you have your CF diffuser as well, have you installed it? What kind of exhaust setup do you have?

Car went to limp mode almost immediately, and I found metal shavings when I checked it. Prior to the install I flushed the system- old fluid was perfect. I also had it glycol tested and it passed with flying colors.
Trust me if it had not happened to me I would have never believed it was possible. But it did, and now I have a new transmission. Ironically they left the old Valeo radiator insisting I need no worry. But I'm not replacing a tranny again, so I'm still going to have to change the radiator after all that happened. I have heard of others that did an external cooler without issue, but I just wanted to share my experience.
Don't put an external oil cooler as it will ceep the transmission oil too cool and that is going to be a problem...

thats odd...i would suspect that there was a problem already brewing and that the tech just needed something to blame the problem on.
Theres too many questions to go about it...but i think if you do the research to get the correct cooler with decent quality, and placed in a well thought out location... i really can't see a problem brewing from an A-A cooler...providing the operating temps to be within 160* to 200*....anything above is catostrophic to bearings and seals, anything below and it needs to be driven harder...

Im not saying that you did not do your research, but i think your tech is full of shat, and wanted you to for out 9Gs...

Its too bad your tech tossed all your equipment, otherwise it would be a good way to spot the problem.

It was perfect before and trashed after a mile with the cooler. I don't completely agree with the mercedes tech- the transmission did overheat but I don't think that was the cause of failure. I think it was the result of a lack of flow through the cooler. Now what caused that restriction I'll never know.
BTW sorry for getting off the op's topic
thanks for all the info and help guys!!!!
I just suffered the gycol curse on my 03, even after I asked the stealership to check for it when I got my A Service. They never did, and told me not to worry about it. Repair estimate: $7800!
I just bought that same radiator... still waiting to get installed. I can't say how well it works yet, but I'm in a position where I need to save as much money as I can. Dealer wanted about $500 for their radiator. Also bought a used CL500 transmission with 21000 miles for $1300 (avg price $2600 - $3800).
From my personal experience; "Prevent, Warranty, & Insure"!
Good luck!
(btw, glycol contamination test is $120 - $180)
