2016 Volvo XC90: engine overheating

Filed Aug 17, 2026 · Engine · AZ

I discovered an engine coolant leak from a crack near the end of the Plastic Coolant Bypass Pipe (part #31368673/32382362) after noticing coolant puddling on my garage floor. There are numerous comments with pictures on-line about how common this part fails on this model Volvo. What's also interesting is that the "pipe" fails in exactly the same location (on top and near the end). Seems to me if this is a known defect and the part is not performing with reasonable reliability, Volvo should provide an allowance to car owners when the part fails.

The low coolant warning went off and the turn off engine notification came on. I turned off my vehicle and noticed all the coolant leaking out the bottom underneath the car. I had the vehicle towed to the nearest mechanic and I was given this diagnosis: Found cooling system low, pressure tested and located a slip line that runs from the coolant crossover tube to under the intake manifold. Coolant pipe runs from the crossover pipe down to the engine oil cooler. Volvo has an updated part number due to high failure rate of the component.

We just purchased this 2016 Volvo XC90 last week from an out of town dealer and it suddenly sprung a major coolant leak this morning while driving and isn’t safely drivable without fire hazard as it’s getting so hot. This model was part of recall on coolant hoses, but is listed as having 0 pending recalls on the federal safety agency website.

We own a 2016 volvo xc90. Purchased used in july 2018. In october 2018, we had to replace the engine. There has since been a safety recall for a part that can leak that we believe was the cause of engine failure. The engine started chugging while we were on the interstate. A turtle icon came on the screen. We took the nearest exit ramp to get off. White smoke was coming from the exhaust. We looked under the hood to try to figure out the problem. The coolant was empty. There had been no warning that this was low or empty. We added coolant. We drove slowly out of the gas station lot to see if this would help. Nothing changed. We stopped immediately and called a tow. Fields volvo madison had to replace the engine. They were unclear with us about what exactly happened. It seemed they didn't know what happened. We did research and found a service campaign s29846:coolant expansion tank bleeder hose for our model car. Several reviews from people that their engine needed to be replaced b/c of this. We asked if this is what happened and they said they were pretty sure that it was. Fields tried to help by contacting volvo. Volvo initially declined any help. We contacted volvo. There was some back and forth but volvo agreed to a partial offer to pay $4,248 toward the repair cost of $12,743.42. We paid $8,657.43 for the repair. The tech's said a spark plug tip had broken off and went through the engine. They noted coolant in the cylinder. We suspected this was caused by the bleeder hose leaking the coolant, causing immediate overheating and spark plug and engine failure. Now there is a safety recall notice for the coolant bleeder hose, recall r29936, dated 6/17/19. It is attached. This oem part issue was pre-existing and unaddressed by volvo. Our engine was operating fine with no notice of pending trouble. We want help to persuade volvo to cover the entire engine repair.
