Just did the job on my 06 CDI. Great video from parts, torque values, and routing of serpentine belt. Outstanding!

Thanks!

Good video super 👍

[@lepadatupetrica8487]

What is the temperature on your thermostat? 92 or 87?
Is duo heater valve can block the coolant and increase coolant pressure and lose coolant on expansion tank?
Thank you

[@pfoxhound]

Did you check coolant hoses for EGR?

[@TedMartin1]

After filling up with antifreeze have you got to bleed the system? If yes how? thanks for a tremendous informative lesson.

[@farerse]

Good video , how are the hoses connected to the radiator? Looks like it twists and seals. I have not seen that connection type before.

DR---BEAUTIFUL EXACTING JOB AS USUAL FOR YOU. SUPERB DETAIL!!!!! DID YOU NOTICE THE TOP BOLT ON THE THERMOSTAT BEING LONGER THAN THE OTHER 2??
ALSO, NOTICED A STRIPE OF BLUE LOCTITE ON MOST OF THOSE BOLTS, DID YOU REDO THE TEMP LOCTITE?? DOES "WIS" RECOMMEND THAT?
THX AGAIN!!

I bought a Borg Warner thermostat, neither of the two holes were tapped, the screws are not thread cutting screws, I wonder how may people don’t tap the holes and damage the housing. The bracket screws are the same length as the thermostat so I torqued those to slightly more 10Nm nearly as the thermostat @9Nm and its easier to tap with the thermostat unmounted.

Car D. Ologist 7.7 litres Antifreeze + 7.7 litres distilled water? Whole system 15.4 litres fluid?
Thank you for this great video

[@mb.warehouse_find4221]

why didn't you tapped it before installing?
just an observation...very detailed thumbs up

[@nimakianipour8831]

how do you burp the cooling system?

[@farerse]

remove the coolant lid and run the Engine to operating temp

[@MikeK-NIreland]

Great videos, will need to do this myself soon. How do you get the WIS System, do you have to purchase it?

[@card.ologist4570]

Yes. Usually can be found on ebay -- a few disks to load onto a computer. Really helps.

[@MikeK-NIreland]

Must have a look as it would be invaluable. Thanks. Keep up the good work. 👍

[@hifibloke]

Idler pulley 35Nm

[@geojbig]

Subscribed and find your vlog so valuable, Thankyou! I have a 2005 cdi, where did you get the high mileage badge?

[@TheDomin8rr]

Very nicely done! I'm just about to reach 240k miles on my '05 W211 CDI & it is a Florida car too. If you're curious as to what might be in store maintenance-wise in next 40k miles, I have documented everything that I've had to replace over that time @ fuelly.com... My handle there is 'PSDCamperVan' Keep the DIY's coming, excellent!

[@card.ologist4570]

Thanks. I'll check it out.
