I bought it years ago for a 1977 300D, the box was a Myle I recall I was one who recently mentioned that the stamped steel impellers are not as efficient in moving water as the factory type with the cast iron impeller. They will also corode quicker but I doubt if that it a factor in 6K miles. Look for the MB logo stamped into the housing to get the best pump Also look carefully into the thermostat housing for large corrosion which would allow water to by pass the thermostat and return to the block without passing through the radiator Rusty, listed below, has the good water pumps but you will pay a core charge, probably equal to the price of stamped steel impeller'd pump. Free shipping (with orders over $75) and no sales tax (most states) will cancel out some of the cost.

Tom, I trust you have checked coolant and engine oil for cross contamination? How hot does it get?

Can't a blown headgasket cause overheating? Are you 100% sure it is overhot? Tried an IR therm on the head?

Re: [MBZ] 1979 240D over heating
Dwight, thanks for the come back. No oil in coolant, not coolant in oil. Was showing no signs of over heating or no signs of creeping up temp the last few 1000 or more miles. Car was running great. I have not run it except idle until hot. since this happened but when I do I get white smoke and a rough idle indicative of water in fuel. I have purchased a block tester. I believe it was failure of the water pump as hoses are new, radiator is clean and not leaks or level fluid drop off. Water pump was replaced less than 6,000 miles ago which for me is two months of travel. We were coming home from a baseball game, was just two miles down the road, I looked down and it was red lining. creeped home the 8 miles by driving until it got to hot shutting down and waiting for it to cool. Then going again and stopping. I need to solve the over heating problem. I am afraid I blew the head gasket or cracked the head. I was hoping someone knew how to check to see if water pump is pumping while car is idling. I hear no strange noises and it looks like the pump pulley is turning fine.
