Hey!

I lost power steering and air conditioning out on track today and I think it might be a belt that has gone. Does anyone have a guide or access to workshop manual to show how I can change the belt? I just fit downpipes to the car so I'm happy to work on it but only if I have the right information! Otherwise I'll have to admit defeat take it to a garage to do

Thanks!

I had sort of same issue. When I started the car the belt would slightly squeak. I also noticed when turning the steering wheel all the way to the left or right it squeaked. I did attempt to replace myself however after getting a quote from MB I decided saving my knuckles was worth it. The belt was cheap about $30.00 CAD so I decided to have all the belts replaced at the same time. Took a day and the charge from Mercedes dealership was about $500.00 CAD for labor, all belts replaced. I had about 100,000KM on it at that time and no issues from then on. Best car I have ever had......

Car has only done 17k miles so wasn't expecting the belt to be killing itself yet! I'll take it to an garage to get changed as it looks like a pain to DIY with oil cooler lines!

broken after just 17.000 miles?? sounds very unusual! which year of production your GTR is??

2018. I was surprised when I had a look myself. Hoping it’s not too much to fix, but hopefully it is just a belt and not anything seized that has caused the belt to slip and rip.

maybe a defective belt...

Makes more sense, most likely and I guess it happens.

I'm hoping so! Cheaper option to fix, just hope it hasn't damaged anything when it was flailing around for the drive home.

Fingers crossed

As someone who has tracked cards for years, I can tell you that the belts take a beating. Its the constant on/off throttle and tensioners pulling on the belts under acceleration and then the sudden slack when coming off throttle.

Ive shredded plenty of belts at track. Just fortunate all my cars run the waterpumps off the timing chains and not belts... *WHEW*

the track stresses the car much more than the road surely, but nevertheless, failing after just 17.000 miles still look abnormal to me
