Hello:

I have a 91 300e 2.6 w/o air pump. It has a belt in fair condition belt but I am looking to replace it when I replace the tensioner . I cannot find any listing for the correct size as all US models have an air pump.

My old factory trained MB mechanic friend said the air pump only injected air to lean out the exhaust during warm up. The state I live in has no EPA regs so I not concerned with finding and installing a pump.

The old belt has a number but it seems very tight . Ideas?

Of course my car will only be used off road for purposes of testing and evaluation.
