Noticed about a week ago my radiator was a little wet at the passenger side edge seam.. appears it started to corrode a little. Now today I see a 2" spot on the ground.. looks like it's time for a new radiator.

Few questions.. #1. can I take it to a local radiator place to be cleaned and repaired, if not, #2. Are all w210 radiators the same out of the same year, ie: E320, E420, etc. Wholesale is $400 on an aftermarket unit.

Five years ago I used a place called "Reseda Radiator" and got a great rebuilt unit at a fair price for a 123 300D.. appears they are no longer in business now.

Thanks!

Fastlane has them for $353.

I'm going to try a "P.E. Haiges" here and get it done the cheapest possible way.

If the radiator fails = new engine time.

They have temperature guages for this very reason!

Where is it leaking? Didn't you show me? Isn't the leak by the top?

Stop leak sealed up the radiator in my dads F150. This was over a year ago and it is still not leaking.

I have run radiator durability testing.
The temperature gauge is useless in a catastrophic failure = engine gone before any possible reaction.

I am working upon a circuit = buzzer + fuel cut off solenoid to kill engine upon coolant loss.

These engines are not cheap to rebuild or replace.
