Plastic Radiator repairs possible?

its possible on domestic crap, it should be possible on the merc, ask at a radiator specialist.

I just used some plastic compound on my '82 300D. Gray color, but I will have to look to see what brand it was. Mine developed a hairline crack along the top just like you discribe. Fixed it about two months ago, still going strong.

Reseda Radiator can do that overhaul for you. You can find them at:

There is a place that sell lifetime radiator warranty for your car... $199 or $179 for 1 year warrranty.

I have a part car... 1988 190E 2.3 with a good radiator... If you want it... I can pull it out for you and ship it. I'll sell it to you for 1/2 the cost of above new. Shipping shouldn't be much. I use Fedex ground for the cheapest rate. Contact me at snipped-for-privacy@optonline.net if interested.

John, You need a new radiator which can be had discounted from Auto Radiator Outlet 800-252-0333. Make sure you specify "Behr" like the original in your car. I paid $264 for a new Behr radiator for my '87 300D Turbo. Make sure you don't use green antifreeze or you'll need another new one within a year. Use the orange stuff that has no phosphates in it. Any Autozone store has the stuff. P.

No... never use Dexcool! That is nasty stuff.

John bought a used tested radiator from me... fairly new rad... OE MB radiator Behr for $65.
