My truck experienced what turned out to be a slow PS fluid leak. It was in the PS radiator fitting area. Both the PS radiator and the hose needed replacing. It was covered under my extended warranty, and would otherwise have cost about $600 to fix. Note that Canadian costs are often quite inflated compared to the US.
The mechanic says that it's not uncommon (not sure how common that is, but I have not seen it reported here on the ROC). Not knowing the root cause, I am not sure if we need to add to our knowledge base about preventing another occurrence.
It's really ironic!
Waaayyyy back in this thread, I told you all about a power steering fluid leak (that was "fixed" by adding extra hose clamps). This fix was applied about five years ago. Please keep in mind, the fact that, this "fix" has worked for five years!
Three weeks ago (when the temps dropped to zero), I found a puddle of P/S fluid on my driveway (it was mixed with the snow, so it was easier to clean up). When I noticed the noise from the pump and checked the reservoir, I added Honda P/S fluid and took the Ridgeline to the dealer and showed them the printouts of the original "fix". They took the "extra hose clamps" off the hose and installed another clamp (non-OEM). I drove it home (30 miles), and the next day there was another puddle! I am, in no way, putting the dealer's service department down. The original "fix" lasted five years.
Here is the final result...There was a "pinhole leak" in the hose. The dealer's service department replaced the...
Oil Cooler Hose, part # 53732SJCA02, Return Pipe, part # 53779SJCA03, Oil Hose Clip, part # 90635S5AA02, and Oil Hose Clip, part # 90635SM4A02 (I put these part numbers up for Speedlever, since I wanted him to understand what hose I was referring to).
All is well now.
p.s. By the way...$200.00, but that's the way it goes (it's not like a car payment every month!).
