Hello all,
I need to replace the three belts on my Four Winn’s 94 170 3.0 GS engine. Alternator 3853536, water intake 3852344, and power steering 3853331 or 3857835. I haven’t been able to find these or Volvo replacements. I took the three belts to Autozone and the belts they suggested are too wide and to tall in the “V”! I’m at a loss and would appreciate some guidance.

Also l’m desperate to replace the coolant hose 3853255. This hose transitions from 1” ID to .75 ID. I’ve seen it advertised but out of stock! Any help here you be good too! Thank you

for the belts, you can just take them to the automotive store and match by length.
Older belts would wear out and look smaller, just by a bit of course but for sure noticeable, mine looked like 1/4 smaller.
Check with another store for belts, normally they have a bunch on the wall.

Otherwise all your items available on eBay.

Just searched using google and "volvo penta 3853255" and found the hose

Then used same search with the rest of the numbers and found everyone of them

Did find 3852344 but also found one listing saying it was superseded by 3850268

Thank you to all who replied. I did bring the three belts to NAPA where they were matched to Gates belts. Apologize is responding late. While pulling a skier the “U” shaped coolant hose, 3852289, decided to burst. I had a new one on the shelf and installed it. Two days later it too burst. This runs from the thermostat housing to circulating pump. Assuming a blockage i stripped it down to the block and head. I inspected every hose, manifold and riser elbow. Could not find any blockage. The engine compression is 180, 190, 185, 180, front to back. The readings don’t indicate a head gasket issue. I did see on this site other GM 3.0 people have had the same problem but different hoses. I’m not ready to put it all back together without finding a cause. Has anyone experienced this issue and found a resolution? Thank you.

Only way to build that kind of pressure is there is a restriction in the exhaust

Compression numbers for the cylinders are way high, I would recheck with another gauge
