Help identifying water pump on M117 (Going MAD)
 

So after 4 thermostats, I still have not managed to found the correct one from me engine. Can anyone tell me what water pump I got? It's not the correct one for the car, it does not fit any of the thermostats I have bought so far, because of the groove in there.

Looks like the type used on the 560SL. Try ordering a thermostat for an '86. Looking up the parts list on Pelican, they clearly show the gasket for that fitting in their parts library for that year and model.

The top location is not the thermostat location, and as a consequence does not have a register for a thermostat. The thermostat is located on the right side of the water pump.

Lol you are absolutely right Frank, man do I feel like a goat now :P

Sondrusen we all have problems like this ,so not to worry.
I remember my car turning up after purchase, and i was unable to find the service brake to release it, has i need to put the car on to the drive . So the forum was the place to find out how i could release the service brake. Thanks for the forum .
