Then I'd suggest changing the cap on that Big Money Waste (BMW).

Master Po...

Master Po, no matter if the cat is black or white so long as it catches mice.

It was the radiator..

I pressure tested it again with a cold engine and I saw the slow leak on the plastic radiator seam on the right side. I couldn't see it with a hot engine.

Also the water pump will possibly be starting to leak at around that mileage - mine did.

I replaced with original item from Benz (wouldn't want to do that job again for another 10 years) and solved the problem.

My original radiator is still on car which has now done 151,00 miles.

Regards

kth286,

Well after I replaced the radiator, it leaking again underneath. It doesn't appear to be the water pump as I don't see a water leak on the right side of the pump. Maybe it's leaking lower left and dripping back. It leaks more at initial starting up and leaks less as the engine warms. Is the water pump a straight forward replacement? How long does it take? Thanks, edge.

Access to the four securing bolts is a real pain. You need to have quarter inch sockets and extenders with flexible wobbles.

Some dismantling of fan and steering pump, and uncoupling of the water pipe from the right handside rear of the pump is also difficult.

I took my time over a long weekend and renewed hoses, 'stat and polybelt whilst I was there including renewal of the antifreeze using proper Benz mix and distilled water. To flush the old coolant completely there is also a tap underneath the exhaust manifold to flush the engine block. Again bad access.

I am sure there is a write-up on here somewhere, if you search.

Best of luck.

Regards
