I love the energy, and the skill 👍🏾 this is how I am working on cars, everything is just a little game and when it all works out, it's a great time.. great work sir
Hi Mike, Thanks!
Hello Sir, Another terrific video. I've been doing cars for 60 years & the so called young mechanics have no idea what a fan clutch is let alone how to diagnose the performance of one. All these kids see is electric fans & even with that their looking for an outlet to plug it in. Great job sir TMP from N.J.
Great video! I love that tool. I am replacing my water pump on my 82 380sl as we speak and the fan clutch bolts are difficult to access. I need that tool!!! I used your shirt hose kit from the thermostat to the intake manifold. Fantastic! Fit like a glove!!
Thank you for posting this valuable and informative video. I appreciate it very much.
You're very welcome!
The fan clutch was one of the things I had to replace when after I had been driving my 190e 2.6 for a few years. The fan blades were actually hitting the engine or radiator.
Nice work and 'comfort' tool. After 20 years+ fan clutches are worn out.
On a 1979 Mercedes 450sl in the book it states to move the distributor to access some bolts on the water pump and wanted to know if that is true. Also will moving the distributor cause timing problems or is it just moving distributor for clearance purposes and not taking it apart?
Great to have found your site!
Welcome aboard!
Is there a way to deal with the heat that radiates from the catalytic converters on a 76?
Hi Kent , I have a 1985 300 td and I need a left rear trailing arm . Do you think a trailing arm from a 85 Mercedes 380 will fit ? Thank you for your great videos .
Yes it will. You will have to change the parking brake cable.
How do I know if my fan clutch needs replacing even though it's not loose or how do I know if it need oiling as my car gets over heated in traffic?
Hey Kent. I was wondering about the thermostat housing mine has some sort of red “gasket or glue or something” along with the black rubber seal that came with the new thermostat. I’m between the housing and the mount where the three bolts attach too. Is it necessary to use that red gasket thing or sealant along with the gasket that comes with the thermostat?😊
Listen to that engine purr!
Glad you noticed... :-)
What's the price of the kit and the special tool? I get so much heat inside my 1989 560 SL this may help. Also I hear a loud gurgling under my hood near the window where the AC Is on. What is going on?
Hello, my SL R106 1977 over heats when I'm in traffic and on drive mode, I checked the fan and it seems to work faster when I'm on stand still with gear on park rather than when gear on drive and foot on brake due to traffic or moving slowly? Any clue why the van is slower while the gear is on drive and in traffic? Do I need to change the fan clutch?
It's also worth noting that it's 35c outside
The fan speed is supposed to slow down as the engine speed increases. That is why it is called a "fan clutch." Otherwise, the fan would be too loud at speed. But it could be running too slow and the clutch may need replacing. There could be other reasons for it overheating. Thermostat, plugged radiator, timing, engine running too lean, plugged exhaust, poor water pump output, etc.
Hi, I have a problem with my 1985 380SL the fan and the belt with it does not move. Do you know what is the problem and how to solve it? Thank you
I have a Mercedes-Benz v8 and there is a problem while trying to operate the traffic is moving, but the fan does not rotate the whole reel, it is stopped, what is the problem?
If I understand you correctly, your viscous fan clutch has failed. There is liquid inside the disk that controls the speed of the fan. It is not uncommon for the liquid to leak out and the fan fails to spin properly.
Good jop
Does anyone know the model of the European 6 cylinder version on this generation of SL?
It was badged the 280SL in the R107 chassis
Have you experimented with refilling the silicone oil inside?
Yes I have and have not had success long term. You have to deal with the reason the old fluid leaked out in the first place. For under $100 for.a new one all that is just too much hassle.
@@Mercedessource Ah that's not too bad at all, considering how easy the swap is!
After going through a few clutches on my 603 powered W126 I threw in the towel and converted it to electric fans.
Excellent
Great video Kent. is 95 degrees Celsius ok operating temp on a 240D W123?
For me that is right on the "edge" of being too hot. Your temp sensor or gauge could also be off. Use an temp gun to check actual temperature.
@@Mercedessource thank you
is a 95c running temperature acceptable for an OM617 turbo? 100c sitting in traffic
In my humble opinion that is a little too hot especially if you are seeing that on cooler days.
Why not just use a solid flex fan.
😎👍
Hey Kent. What do you consider hot for these cars?😊
85 to 90C is best. You run long periods around 95 or above and you will overheat plastic, wires, and rubber components in your engine compartment.
@@Mercedessource Thank you for your work and presentations. Sometimes the simple answers are the best answers. Keep up the good work!
