    i’m up in Massachusetts for the summer and I noticed the the car had a pinkish liquid coming out from the bottom of it when parked. I asked a mechanic up here and he said it’s the coolant but it looks like my car has two coolant cases. Do you know which one the white one is for? The car hasn’t...
  2. R129 SL-Class
    May be a new one for the forums, unless my searching skills are lacking. This started out of the blue while on the highway today. Temp climbed to about 80z and then stayed there, even after arriving at work and taking the keys out. Took the car out for a drive later on and seems to respond to...

    Went to Walmart to buy me some coolant to do a flush but they weren’t carrying any zerex but I saw this on the shelf which was on sale for $9.99. Would I be ok using it or should I stick to zerex?

    Picked up a 1994 e320 Wagon for about 3K. Headgasket wasn't leaking, harness was done at least once. 220K miles. I got a PPI and here is the things they found. They mentioned there was some leakage at the water pump but I was NOT expecting it to be something that needed to be done right away...

  6. C209/A209 CLK-Class
    '07 CLK 350. Got the warning message "Top Up Coolant" this morning and realized I have a coolant leak. I'm not exactly sure how long it's been leaking. Do I need a new tank, or can I just use sealer to stop the leak? I went to autozone and they said there's a coolant leak sealer or something of...

    Hello all, I’m new to working on cars in general and started working on my grandpas old 1984 123w 300d. I did a coolant flush and the coolant that came out was green but the Zerex coolant I bought that was recommended for “all Mercedes models” is blue. Can I use the blue coolant after flushing...
  8. W140 S-Class
    Today I bought my first Mercedes-Benz. This is a 1998 W140 S320 with the M104. I love this car! It was a single family vehicle prior to my purchase. It’s amazing. It has a few small flaws like the soft close doors and trunk work intermittently. My bigger concerns are within the engine, it’s...

    So recently i had a bad water pump and a leaking radiator. A week ago i knew that everytime i saw coolant dripping underneath, it was because of the radiator. So i replaced the water pump and the radiator, also by mistake i broke the temperature sensor that goes above the water pump , i also...

    Hi, Could anybody please tell me if crankcase coolant drain plug has a gasket? It is hard to see and I do not want to remove it all the way. Could not find much in WIS either... [2007 B200 Turbo W245.234]

    My coolant light came on a month ago, and I tried the following, but it still has not deactivated. -Replaced the coolant level sensor -Replaced the windshield washer reservoir sensor (as I’ve heard they use the same circuit). The back story: Coolant light randomly turned on one day after a...

    Hello, I recently bought a sl500 from 1994 that has about 160k miles on it. I noticed in my garage that there was a "warm smell" (I don't know how to describe it). The car had been off for about 2 hours and the engine block is still airy hot. I am unsure whether it is a water pump, thermostat...

    Hello there, after i changed my waterpump (which was completely and utterly gone) my 1999 mod, 220CDI has started to leak from the hose on the pictures. I tried to google, but i cannot figure out what type of hose it is. It does seem like it has been cut once, as the edge looks really rough. It...

    Good Day guys This is my first post here. One of my cars, 2008 model, M271, C200 has seen oil in the coolant box, so i replaced the engine oil cooler and cleaned the coolant box, but some oil seems still coming up to the coolant box and i started to suspect that it is from transmission fluid...

    I have a 2009 ML320 Bluetec diesel with 64,000 miles. The top off coolant sensor was activated. I purchased the purple Zerex G48 antifreeze for it. When I looked in the reservoir, it was full of green antifreeze. I'm not going to mix the two. However, should I drain and flush the system and then...
  18. W202 C-Class
    Hello I have a w202 c180 1998(408 000km) and the car loses power randomly, what happens is the car will drive normal and then the car will lose power and I will look at the dash and the only abnormal thing is the coolant gauge shows 0. This happens most often when I drive on the N1 or I am stuck...

    Hi all. I'm currently experiencing issues with my 2004 C230 Kompressor M271. It has no issues with performance, but the "Low Coolant" and "Reduce Engine Oil Level" warnings were so frequent that I stopped driving it. In May I had the oil cooler changed. Afterward, the same problems persisted. I...

    Found my entire trans covered in blue, and jacked her up to discover blue coolant leaking. I was aware of a coolant issue as i regularly refill the overflow but never had the whole underside covered in blue. it seems to be leaking out of the back of the head on the exhaust side. I checked the...
