I always enjoy working on my merc. Im glad to see others do as well

Thank you for this video I bought a parts car for my build. More power😊

Thanks--very informative video! I have an '84 500SEL.

Same year as my 300sd !

Always proffesional 😎

Always nice to see the differences between the generations and engines. On the OM603 the oil cooler is just behind the front bumper down low. This allowed for a larger radiator within the cowl support. Th PO replaced the original radiator with a full aluminum replacement with an extra core run. In this configuration you HAVE to use the factory fan bolt tool as the clearance is very reduced. The total aluminum radiator eliminates the plastic failure at the radiator entrance. Might not be available for the OM617 but it's worth a look

I shelled out two R4 ac compressors, the Japanese ac compressor was only around $300 , the R4 is around the same price!

Thanks for this... Will be replacing the radiator on my '83 300SD within the next couple weeks!

Nice job. Pierre approved 👍

I replaced the rad in my 85 300d and I don't remember it having an oil cooler. I definitely did not remove it if it did have one. Was that original rad a Beher? Mine was and they wanted $300 for a new one and that was almost 20 years ago. I bought the less than $200 German made one. I'm cheap! It solved the problem of the thermostats constantly freezing up on me. Looks like you made a good job of it but I'm still waiting for the injector swap. Lol

where did you get the "procedure" you mentioned? thank you

But the ac works MUCH better and freezes me out of the car on the hottest days.

I enjoy your videos but I had to cringe when you directly removed and installed transmission cooling hoses on the plastic radiator without providing counter support on the fastener attached to the plastic radiator. An open end or adjustable wrench applied to the radiator's installed fitting can offset the torque your wrench supplies. Expensive tragedies can occur to plastic radiators by subjecting them to such stresses and protect the radiator. Also in a similar Mercedes vein what you did is similar to removing the oil line on the guage on W123 and R107 models (cars with oil lines to the guage) without providing counter support. This can cause a non leaking guage to become a leaker and leave you with oil on your leg. These delicate parts need to be protected to avoid needless damage and expensive repair. Please edit the otherwise informative and entertaining video so others are not encouraged follow your flawed removal and install procedure. I am a subscriber and please keep up the good work. As others comment your enthusiam and determination are contagious. Your previous door panel clip repair enabled me to fix mine (thus far)! I often muse if you are a JB Weld principal or shareholder.

Get rid of that junky R4 GM compressor! I converted mine to a Japanese system, you have to change all the hoses and condenser. The whole job cost me around $1200 because my brother in law helped me .
