Thank you - very helpful . I did see a video where the main turbo air line was removed from the air filter side only then the bracket holding the solenoid above the T stat was removed and the radiator hose then the T stat was removed . Less involved but I like your method because you also replace those old hoses .
Good video, just got done doing mine also. I have a 2014 C250, think I have everything bled right. Gauge sits where it normally did...when I have ODBII reader hooked up I'm getting temp range from 93C to 222C when tstat opens and goes back down, is this a normal range for this car. Tstat says it opens at 103C.
Good afternoon Frank I have a 2014 c250 mercedes I noticed a small leak comeing from radiator hose it's coming from the side of hose that is connected to thermostat housing don't see no leak around the house just were hose is clipped to housing do need to replace hose or housing
I would replace the whole unit. Same thing happened to my 2014 C250 and when I pulled the thermostat housing off, the thermostat itself broke inside the block. It took me 2 extra hours to get all the pieces off, it was the original factory unit. What a pain it was, but after I replaced it my car runs like a champ and not leaking coolant anymore. Good luck.
Got another question I put everything back together and I have a small drip on the main hose that connects to the center of the thermostat (the largest hose connection) Does that hose connection have two retaining wires or only one? I ended up having another retaining wire from that hose and I don’t see where or how else it could be attached the connection only shows one place where the retaining wire locks.
@@franksautomechanic809 I actually had to buy a new hose o ring the old one was just old and wouldn’t seal. Out the new one in haven’t had any problems since
also what tool do i need to loosen the clamp for the intake hose on the turbo side? that little sucker is impossible to get to even with a short flathead screwdriver. I feel like I need something with a bend in it
Very helpful video, so do you need to put a special sealant around the thermostat before you install. It came with its own but I want to ask if I need silicone
I broke mine, just buy a 5/8” hose with two hose clamps. I glued and taped my old hose back together and it works well. That hose is really brittle and not very flexible. Good luck, keep me posted on what you end up doing.
Thank you for the video! Very helpful! I have a question the 5 bolts to the thermostat housing do they have a torque spec? I’ve searched online and I saw a 25nm mention but that seemed like a lot of torque. Thanks in advance
Every bolt and nut and screw has a torque spec to the wheels and all the way to internal engine components. You can find this information either by web search or if you have access to any sort of automotive help desk program that can give you specs.
have you ever installed an aftermarket thermostat. just seems that mercedes is overpriced. I have a 2014 c250 base. i am finding aftermarkets for anywhere from $50 to $90. benze wants $200. your thoughts. thanks
Patience, and the right tools you can do it. I had my factory thermostat housing go out and the thermostat broke off in the block. It took an extra 2 hours to clear out. I am relentless but I wanted to give up at least 3 times. Once you’re committed there’s no turning back. But you will feel a extreme sensation of satisfaction if you repair it yourself. You can do it, just make sure that you have at least 5 to 8 hours dedicated to work on it. In my case I had the thermostat breaking in the housing and binding to the block, which ate up most of my time. This job will take 2 hours if there are no issues. Good luck, please keep me posted on your progress.
I super glued it back together and taped it with Gaff tape and it works fine. If I need to replace it I will buy a hose with two hose clamps. So far my car runs like a champ!
