Thanks for video did my thermostat in 30 mins watching this, only had one problem that the new thermostat housing has a hole in bottom where as mine didn't so I just removed the innards, new sensor and gasket then swapped to my old housing, car finally gets to operating temperature and mpg has gone up a lot! Cheers again!
Is it have only 1 thermostat or they are small and big one? Because my 220cdi 143hp is work on 60° and very hard go to 80° , and I think that the thermostat is problem. Thank you for helping me
@@Enginesetc Did you have an issue getting the right part? The one I got had an outlet hole on the bottom of the housing which isn't on the original, it looks like the new part you have has this extra outlet also but the old part you removed didn't? Cheers 👍
@@mikeb6385 Nope, euro car parts, enter reg and then one option. Which outlet hole sorry, is there a moment in the video you can see it? it has the spout for the expansion tank line and the hole where I cut the thread for the bracket, that's about it?
@@Enginesetc thanks for your reply.. It's where you have your index finger when you are comparing the old and new together, like a spout of about 20mm diameter.. I ordered mine from gsf via their website using the car reg.. I'll try euros! Thanks.
@@mikeb6385 ahhhh yeah, I've got my finger inside of it haven't I! The quite wide and pronounced circular shape. Ok it's just a moulding on mine, it wasn't an actual hole that let anything through, it just seems to be a weird design choice in the moulding. It should be same on yours in that it doesn't actually go anywhere :)
I have the same moptor and the temperature is around 100, now the water pump is smaller, hasn't it been changed for sure 100,000 km, so I'm wondering if I should also change the thermostat, is the water in the bowl boiling to some extent and disappearing, and the small radiator for heating was clogged and had a weak flow I hope that my problem will be solved, but I don't know if I should also replace the thermostat
@@Enginesetc I solved the problem with a new pump as well as the thermostat and flushed the entire system and now there is no problem, the temperature is 90c sometimes it gets a little hot but the water doesn't boil :)
If the system isn't coming up to temperature then there is no need for the fan to run. The fan will cut in when a certain temp is reached to help maintain the optimum running temp should cooling be required.
My expansion tank is broken and i want change thermostat at the time Thank you so much for this video very good and completed !! I love your electric tool can i have the reference ? Sorry for my bad english 😅 thank you one more time from france buddy 🙏🇲🇫
No problems, hope it helps :) This one is a "mac tools" electric ratchet. If you google electric ratchet or "cliquet électrique" it should bring them up and then just choose a brand. I love dewalt tools :) Your english is better than my french, please don't apologise! thanks for commenting
At 4.46 when u take the engine cover off, is that red thing ?? Rear right of engine not the engine dip stick, although its only a cap, no stick. The gearbox dipstick is further back nearer the screen and lower down ! Ive got pink coolant in my CLK, is that a higher or lower level than the blue ??
Hi Arnie, nope thats definitely my gearbox dipstick tube, might just be the angle on camera. I filled my gearbox through it when I did a service and some repairs on it so definitely gearbox one :) There's nothing wrong as such with a good pink coolant but Mercedes specifies the blue one, probably some different properties in terms of anti corrosion etc. As long as you now stick to the pink one, never mix the colours or they can turn into a gel and block tubes, leading to overheating etc. If you ever decided to go to blue, drain all the coolant, fill system up with water and flush it through, drop that and then you can change so you dont mix any :)
@@arnietwo11 Ok bud, let us know how you get on. Be thorough and remember thermostat is closed until operating temperature so you will probably need to remove thermostat and flush water through from that side as well to ensure you get all traces of the pink out!
i got problem with my w209 clk 220 - it show i got problem with heater booster control module - line is interupted.. but i dont know where is location of it so i can check :D

Thanks, glad it helped! Ah ok, annoying but least you got sorted! The parts gamble is always scary isnt it haha! Thanks for commenting bud
ive heard that the vito has same thermostat housing, but with hole at the bottom
might have gotten mixed up

Hello, only the one as far as I am aware. Mine works now, I had same issue was sitting around 60 now it's perfect just above 80 as it should be :)
Thanks for showing, i do mine this afternoon, it helped a lot!
No problem, glad it helped and thanks for commenting 😀
Cheers! I have to tackle mine this week and this really helps! 👍
Glad it helps, good luck for the job!

Would be interesting to see the stat before and after.mine is going over slightly but blowing warm heat even on long journey. Any thoughts?
Is it going up to over halfway? I would recommend changing it and making sure all air is out of the system just to rule it out as a cheap option
What about hole at the bottom?) In my case, the antifreeze is leaking through a plug that was plugged in there.
The red plug at the bottom of the rad I assume? That is a coolant drain hole, yours might need tightening or new plug/gasket
Oh. thanx! Yeah, I had to redo the cork. It was plugged with a 22mm diameter metal plug and sealant@@Enginesetc
@@artinstroukeprod ah good to hear you got it sorted :)

Yeah I would also recommend thermostat as well if you're doing water pump, might as well for the small extra cost to eliminate most issues
@@Enginesetc I solved the problem with a new pump as well as the thermostat and flushed the entire system and now there is no problem, the temperature is 90c sometimes it gets a little hot but the water doesn't boil :)
Would this part stop the fan from working ?
Probably not, there is however a coolant temperature sensor which could if you google where that is :)
I've researched everywhere I don't know where to find the coolant temperature sensor on this engine , its doing my head in now
If the system isn't coming up to temperature then there is no need for the fan to run. The fan will cut in when a certain temp is reached to help maintain the optimum running temp should cooling be required.

what coolant are you using?
I used blue coolant, G-48 specification is ideal but any blue coolant should be fine. Comma G-48 is specifically what I used
Very nice video❤. Ive HAD to sub your channel!
Thanks Peter, much appreciated!
for w209 clk220 will be the same operations to change it?
Yep exactly same engine so same procedure!
At 4.46 when u take the engine cover off, is that red thing ?? Rear right of engine not the engine dip stick, although its only a cap, no stick. The gearbox dipstick is further back nearer the screen and lower down !

@@Enginesetc ok i will flush system and go with the blue!!!

Thanks. Just one question, what did you say you used to clean the mating face of the block?
@@MrMagicNetwork sorry for delay, just used a microfibre towel
i got problem with my w209 clk 220 - it show i got problem with heater booster control module - line is interupted.. but i dont know where is location of it so i can check :D
Doing some googling, it looks like it's behind the front right (if you're sat in the car) wheel cover! Good luck!
Really helpful video. Thank you 👍
Glad it was helpful, thanks for commenting! 😊
How much coolant does it take
seems around 8 litres give or take
My engine goes very hot and starts slips 80-60-40 km/h … don’t take the water from pump. Is this the problem
Depends what you mean by slips? Can you give any more details?
Bonjour, comment avez vous vue que le thermostat été hors service ?
Bonjour, ma voiture n'arrivait pas à température lors de longs trajets sur l'autoroute et la température mettait trop de temps à monter !
Google translate hopefully ok!
@@Enginesetc merci
Great video very helpful 👌
Thanks buddy, appreciate it!
Top bloke thanks mate
No problems, glad it helps!
Tnx
No problem 🫡
Молодец
Thank you
