I feel really dumb to ask this question... I bought a 1994 W140 diesel about a year ago. Only this summer I found out when going up hills, say about a mile, the temperature will go up to 110 degrees. I flushed and replaced the coolant, and new radiator cap, nothing helps. I though something wrong with the fun clutch and then I realized that the two fans I was checking were not the radiator fan I was thinking. At some point the radiator was removed and never put back. My car has been running without the radiator fan for almost a year. Surprisingly, even in the stop and go condition, 100F with A/C on, I don't see temperature goes over 90. Now I need to get a new fan, new clutch. My question is, will the fan/clutch from a gas version fit on my diesel? I checked epc website, they have different part number, and gas version seems to have a plastic cover that covers the clutch, but diesel version only have fan blade and clutch, use a bolt attach it to water pump?

Any input is greatly appropriated.

Thanks for reading and have a nice weekend.
