  • My $1,000 Benz tried to kill me! In this video, I'll show you how to smoke test a Mercedes to find leaks. Then I'll show you how to replace the thermostat and water pump replacement. I've done this a thousand times and never encountered a more difficult task than this Mercedes. You can't believe how bad the engineering is in this car!

    You’ve done an incredible job so far ! Don’t let a leaky coolant reservoir get you down🤬🤯😮‍💨 This is way cheaper than the dealer . Here in Canada it’s $178 per hour labour at the dealer 😳😳😳

    Look at it this way Mike, you're working as a mechanic for a dealer and you just had all these problems, the service manager is mad and wants results. In your case yes it was frustrating, but you did it, and your frustrated, but nobody yelled and it's finally done, and you learned a lot while doing this job. Great work.

    Mike, I've often wondered if there was a special German auto vocabulary to use while working on them or can you use the Land Rover/Range Rover one, with a slightly fake German accent? Great video as always and Thank You to you and Randy for saving the deserving Mercedes and BMW's from the foul clutches of LKQ at great personal cost and mental anguish and yes, a person does have to take a large part of a day to admire that wonderful German engineering as you tear half an engine down to reach that one bolt.

    Hi Mike, I have 2 great loves in my insane automotive life Mercedes Benz and Range Rovers, got 3 mercs and 2 Range Rovers. You truly need to buy yourself a Range Rover as you will never curse or doubt mercedes engineering again keeping Range Rovers on the road or off road as the fancy takes. But there truly is not anything quite like a well sort Range Rover, only problem is getting them that way 🤣🤣🤣 Thanks for the brilliant content and give lola a hug from me. Got 6 Black Labradors and a Jack Russell to add to the insanity here as well.

    I noticed your ASR light is illuminated... I had one car (a 1993 S500 w/ same M119 engine) that had a surging idle and ASR light, the problem ended up being a broken MAIN power wire to the throttle body motor (inside throttle body) broken solder joint inside throttle body harness.

  • @petercollingwood522
    @petercollingwood522 ปีที่แล้ว +1

    Are you sure it was the vacume leaks that caused the surging? That model doesn't have the garbage eco freak wiring harness does it? Because that would be a symptom of that if it was still in the car, though I think they got rid of them by 98.

    The abs asr issue can be many different things. Your autel will give codes, I’m sure.
    With the age of the car you may need an abs motor. This is a permanent magnet motor with carbon brushes that wear down with age. If you have patience you can remove the motor from the mounting block and order just the brushes from McMaster carr.

The new water pump and brake pads are a good thing as well as cheap insurance my friend, bravo. Get the vacuum leak squared away, have a cup of coffee and call it a day ☕☕ 🤠 ..

    All my euro cars run at 80°c. You may have a bad rad or you got a bad /wrong thermostat.
    You may have gotten a winter thermostat. It should say on the box or paper inside.
    Did you test the old thermostat. Your original problem may have beeen the water pump and not the thermostat.
    When my 85 300d would overheat, and other cars, I could take the thermostat out and go without it till I could get to it.
    That design you have looks bad.
    I don't think a German designed it. Maybe a Frenchman or Russian. 😅😂😅😂😅😂
