I have a question I own a 2016 Volvo S60 T6 with less than 47k miles on it. Recently the alternator froze causing the serpentine belt to snap and I think damaged the head. I am showing zero compression in the one cylinder I tested. A head job and new alternator from Volvo is $9400 is it worth inv…

While costs certainly vary in different parts of The US, I am sure that you could find a qualified independent foreign car specialist to do the required work for far less than $9,400.

The biggest cost is the head assembly itself Volvo won’t send the old head out they guarantee the work for as long as I own the vehicle but insist on a $5k head assembly from the factory I am torn

[image] FrCalamari: Volvo won’t send the old head out That would seem to imply that you are relying on a Volvo dealership, which is sure to charge much higher prices than an indy foreign car specialist. There is really no good reason to take a 7 year old car to a dealership, as long as there…

I’m having trouble understanding how the accessory belt snapping can damage the head. Are you sure you don’t mean the timing belt (if your car has one)?

Looks like only the 3 liter engine has a timing chain. All others have a belt. All are interference engines. The belt has a 90K mile replacement interval but I’d bet there is a time component, too. 7 years seems a little short but I cannot imagine how a failed alternator would cause this. But unles…

[image] lion9car: I’m having trouble understanding how the accessory belt snapping can damage the head. I’m guessing that, on this engine, the water pump is driven by the serpentine belt, and that the engine overheated, thereby damaging the head. That’s the only scenario that I can come up …

I know it sounds incredible but the serpentine belt snapped when the alternator seized snapped and wrapped around the crank screwing up the timing this damaging the head trust me I am having a hard time believing a $450 part caused all this damage

Freak accident. I assume you would not feel any better if it was a $1 part :grinning: If this was mine, I would invest the small amount to have someone look in the bad cylinder with a borescope to see if the piston is damaged or it’s just a valve stuck open. Then, if it looked like just the head, I…

That sounds reasonable, I’m going to start looking for independent shops, where I am in South Jersey there are not many foreign car specialists nearby but I can have it towed anywhere

I am now looking at independent shops as every one advised thank you
