1 couldn't get my 1987 300d to run cool with ac on the 100f plus days after replacing almost entire cooling system. Even new clutch fan. So I ordered a pair of 12 in mishimoto fans to replace clutch fan. They fit perfect and now I can run ac on high on 100f day and temp runs just above 85c. And notice in exceleration. I was surprised how much drag a new clutch fan put on the motor. I used a fan controller from davies craig for dual fan. It has a trigger wire for ac. Should I use it or stay with the way it comes on from. Benz. Your videos have been a huge help. Thank you Ralph. 😊
Hmm. There is no doubt that the water pump mounted fan draws HP away from the engine. What is odd though is your claim that your delta t is about 15C engine temp between OEM and your add on version. That is something I have never seen before. Most issues are with "high temp" are related to the sending unit being bad, bad water pump, gummed up radiator, or very frequently also a gummed up block or head. With a working OEM fan and the radiator being in good shape there is typically maybe a 5C difference between OEM and an electrical fan. I would use an external fan switch like the one described in another video of mine. You will need a relay as the fans draw quite a bit of current. Good luck and I am glad you find some of the videos helpful.
Thanks for the video! I am doing this as well as other things, but I have a problem: the screw hole on the water pump pulley seems to be blocked by something... Like an inner layer. The hole goes in a few mm with no threads, then there is some metal blocking the screw from going in. Any idea what could be happening? Thanks! I did crank the shaft with the fan off because i worked on the valve stem seals. Do yiu think the pump pulley has some inner layer which needs to be rotated?
@@straybenzes Thanks for the reply! I got it! I cranked it a few times to pressurize the system (like after an oil change), but decided to re-check the holes and, lo and behold, the inner plate had moved and I saw a bit of a bolt hole peeking through. A few minutes of cranking and checking, and the holes were lined up. Got my fan cleaned and new clutch in! But now, having started it up (I changed the valve stem seals), the timing chain is making noise and I'm getting what seems to be blow by... So that will be fun to figure out 🤣 Cheers!
That was terrible my friend. I could not hear you over the sound of the engine. Also, I cannot believe you put Chinese junk on your benz. Within 6 months you will have to replace it again. You can get genuine MB parts on the internet for much less than the dealer price. Boycot Chinese junk!
Hallo Herr Danler. I wholeheartedly agree with both of your assertions. I will improve the video editing and quality in upcoming videos. I share your disdain for low cost parts, but this particular car is not worth dropping >USD440(!) on the OEM clutch, which is more than 15% of the car's current value.
@@straybenzesHi Ralph. I agree that some cars are not worth high price parts especially if you are not planning to keep it. That price of $440 seems excessively high. Is that the dealer price? Good luck with the project. Are there other things you plan to fix on this car? I had a 300D turbodiesel in the early 2000s and fixed mechanical things like balljoints, tie rod ends, brakes and window regulators after I bought it. Other than that the car was almost perfect and had 280,000 miles on it when I sold it to a friend and did not burn a drop of oil and ran great. I wanted a faster car so bought a 2002 Audi A6 2.7 litr twin turbo V6. That was a big mistake. Piece of junk. Anyway, I will keep watching your video's. Oh, are you Austrian or German and are you here in the U.S.A.?
@@wernerdanler2742 Yes, that is for the OEM part from the dealer. Other pending videos in the works are fixing the cruise control amp, what to do with old catalytic converters, etc. Born and raised in Germany and now based near Philly. Hoping you got your car brand confusion sorted out and are happy with your current vehicle choice. All the best!
@@straybenzes I was born in Germany and was sent here and adopted by Americans at age 7. I have a 2001 e320 now. It is a solid car but was more neglected by previouse owners than I thought. Needs motor mounts now. Had to fix the transmission just after I bought it a couple years ago. Most problems are cosmetic so I plan to keep it. Goodbye for now.

I would take the belts off and take the pulley off that shaft so that you can make sure that there is not a broken bolt in there preventing you from
