I watched several videos on replacing the coolant thermostat but I have to say this video is the BEST. It explains every thing step by step. I'm not a mechanic at all but after watching the video I feel fully confident to do the job on my own if I have the proper tools. Thank you. Keep up the excellent work.
Thanks Rsmatd. Part of my video shoots are that I try and have the subject matter as clean as possible to aid in visualization. I appreciate your noticing and commenting. Dean
Excelent video! With quality audio, video and very well explained Also I like the story in the description of Your Channel talking about your dad Thank you!!!
Thank you for viewing. It’s not often someone is as astute at picking up on the work including sound editing and lighting it takes to produce a good quality video and I appreciate your compliments. Dean
perfect video, he took care to prepare everything very well including the cleaning of the pieces for this movie, about the sound, it's magnificent. if I could give stars I would give it the maximum, 5 stars. Keep up the success and thank you very much.
Thank you for the video as I followed step by step but on a 2006 MB CLK 350 W209. But I cheated as I also replaced the oil cooling and filter housing adjacent to the thermostat.
Succinct and thorough. Even nice background music which I used Shazam to download a copy. Thanks for the trouble of making this and the good information. This car is pretty strange in that it has a pellet in the coolant recovery tank and I have heard for the first coolant change you don't have to do it for 150,000 miles or 15 years don't know how true that is but I thought I would change the thermostat as a preventative thing when I go on a cross country trip in May . I have a retired friend who has a Mercedes shop for 40 years and I think he's just going to undo the thermostat, let whatever coolant there is dribble out, and then replant it as necessary eliminating all that bottom work But anyway thank you for the nice video it is exemplary for TH-cam do it yourself videos
Please help, when disconnecting the coolant temp sensor the little gray locking tab shot off and i cant find it or a part number for this connector anywhere. I noticed you had a separate connector, could you tell me where you got this connector or a part number? I'm in a world of shit because this is the wife's car. Awesome video by the way, thanks.
It wasn’t a spare in the video, it was the original. Contact the dealer for the part. Luckily, it’s just a safety locking tab and technically you don’t need it for the sensor to work. Just press it back on until you get a replacement or find the one that popped off.
You can go to your nearest Mercedes dealer and purchase just the connector for the temperature sensor. Remove the clip off the new connector and you’re good to go. Mercedes generally has the connector for all sensors. Hope this helps
I'll go ahead and ask. You use a designation "nm" for the torque of several of the bolts in this video. Is there a difference between "nm" and "Nm"? [Aside from the obvious capitalization, I mean]
Good luck Luis. As a follow-up, I 'would' recommend going ahead and replacing that upper pulley you see me remove and talk about. After this video, that one starting squeaking and I actually replaced both that one and the one beneath it. They're pretty cheap, and on some websites, you can buy them both together, which is what I did...and as long as you have the belt removed anyways.....give me a yell if you have questions during the install.@@LuisMartinez-zd2vl
@@PilotViewProductions I did the whole thing that morning. I replaced 2 of the serpentine belt wheels (but not the tension release wheel). I got the flu that same day. Finally felt good enough to drive it a short distance. Radiator hose blew off. I suspect I need to replace that gasket or maybe the hose. Can't quite seat the hose in the thermostat assembly securely.
I wouldn't trust the fit until those clips click into place, whatever it takes. Make sure the hose collar is not bent since it's so fragile.@@robertvaldez6544
Well, being as how I can't talk to you in person, I have to make certain assumptions. 1: that the housing in question is the thermostat housing. 2: that it's leaking coolant. 3: And this is a stretch...that it wasn't leaking before you changed it. That's a biggie. If your car is leaking coolant from around the thermostat, the thermostat will have to be removed to discern why. Once removed, you should be able to see if the gasket was installed and if it was, that it was installed properly. You would need to check for old gasket material stuck to the engine block that would have precluded the new gasket from seating properly. That old gasket material would have to be fully removed before remounting the new gasket and thermostat. Could it also be that if you installed a new thermostat, that it was bad and had a crack in the housing? I would, again, have to ask 'where' the leak is coming from....does it appear to be leaking around the base of the thermostat. Perhaps only a powerful shop light would reveal this while the engine is running. Lastly, once all the above is rectified, I would suggest using a gasket sealant in addition to a new gasket when refitting the new thermostat. Hopefully one of these ideas works for you.
@@PilotViewProductions I appreciate the quick reply👍 I will be checking everything again. I might just need the sealant and a new gasket because everything seemed fine when I put it on. Hopefully I can get it done soon. Thanks again 🙏
Hi Su Ma. Thanks for viewing. Yeah, if you were quoted that much for the thermostat and sensor, you most definitely were about to be overcharged. You can see what I paid using the link under the video description. Dean
@@PilotViewProductions thanks for your response Dean. Yes I ordered one for 25 from Ebay and it should arrive in 4 days! And yes I looked up the code it was the same PO128! thanks you so much.
@@PilotViewProductions Dean one more q: how long did the thermostat change take? When I checked online it said it can cost up to $800... that seems a lot, but I am sure they are dealer prices for per hour charge- I wanted to find a local mechanic.
I'm sorry I took so long to reply. The website doesn't notify me when folks post comments as part of other comments. It's difficult for me to say how long due to the fact that I was setting up lighting and multiple cameras. If I were to 'guess' based on my doing it from scratch without the 'overhead', I'd say it would have taken me about 3 or 4 leisurely hours since I had not done this repair before. @@Fraumannal

Excellent video. Perhaps the best Mercedes-Benz DIY video I've seen so far. Thank you!
Thanks for viewing and for the kind comments. Hope you’ll check out some of my other Mercedes videos
@@PilotViewProductions Will do!
Best auto repair video I've ever watched, congratulations!!!!
Thanks Sidnei for viewing and for the kind comments. Hope you'll check out some of my others on the Mercedes. Dean
Your engine bay looks spotless! For a benz over 10 years old, it looks pristine!

Great video down to every detail
Thanks D-T-Don
I’ll be doing this project this weekend weather permitting. Perfect step by step instructions. Excellent video.
Thank you and good luck

Appreciate the kind words. Yeah the underneath work makes this job harder than it needs to be but I don t have a lift available to me.

No, no diff. Newton meters

So I replaced the upper radiator house but now the clamps won't hold the hose in right comes loose after I drove for a lit bit any suggestions
You have to press the hose inward until the clamp 'clicks' in place. If it continues to leak after that, I would suggest replacing the 'O' ring.
it wasnt leaking the clips for some reason would not hold it it in place

I wouldn't trust the fit until those clips click into place, whatever it takes. Make sure the hose collar is not bent since it's so fragile.@@robertvaldez6544

Thanks- I am confused now- I was quoted $215 for a new sensor and thermostat at Advanced auto- I may be being ripped off... !
