When should I replace the timing belt and water pump? What is the average cost of both?

 

Your owners manual will tell you your service intervals. If you don't have it, Volvo's website has them.

Good place to get cost estimates is here: https://repairpal.com/estimator

 

what year / model? Most timing belts are due at 10 years/120K some older models are more frequent and some of the S40s with a specific engine code are longer. Volvo water pumps are fairly stout and most last 2X the timing belt but you need to inspect for any weeping. Here's a handy link to the factory service bulletin. Just look at the timing belt cover or the firewall build plate to get your engine code (or use a VIN decoder).

Yup.....obvious answer is owners manual. Real world answer is users, and that's what I'm looking for. Further, no time limit on water pump. Far too many cars are ruined by a blown pump and a driver trying to make the next exit.

 

Hmmm...I thought I had the YMM in my initial post. 2013 XC60 T6.
I went to the dealer last summer for read brake pads. $300 later, as I was walking out the parts guy says "you need a special tool". Of course I do....right? So I ask how much. He said over $100k. What????? He said to go talk to service. Well, they saw me coming. He tells me the parking brake is actuated in park and if you try to bypass it you will ruin the software and it will need to be reset.....at a cost of $2500. OK....I bit and another $500 to install the pads I just bought....I will NEVER go back. Fast forward a year and the car ripped up the set of pads and I ordered a set and rotors online for $200. I figured out how to work around the parking brake actuator. All BS from the dealer. THIEVES.

 

You don't have a timing belt. So replace the water pump if it leaks.

 

My owner’s manual says I do.......

 

the 6s have a timing chain and a serpentine "drive" belt for accessories. Its the 5 cylinders that have a timing belt.

 

No it doesn't.
