[Not my XC]

Sorry, I'm new to this forum and site. My son has a 2001 XC that I'm trying to fix. My question is on the tag on the Timing belt cover it says the engine is a B5244T3, while the emissions tag on the hood says it is a B5244S. Which one do I buy parts for? Are they the same engine, or has the original engine been replaced.

I don't have the answer off the top of my head. What parts are you looking to buy? Online sites like IPDUSA and FCPEuro require you to enter your make/model/year when buying parts and then will guarantee fitment of the part. This approach has worked for me so far.

while the emissions tag on the hood says it is a B5244S.

5244T3 is the turbo engine you have in your car, 5244S is the non turbo version that was available in the v70/s60 but not the xc.
Maybe someone installed a used hood from a non turbo car.

It's definitely got the turbo. Thanks now to order a bunch of parts and start tearing it down. I didn't want to do that until I had some kind of confirmation. The last Volvo we had that I worked on was a 78 245.
