944 Power Steering Cooler-to-Reservoir Hose RepairI no longer sell a replacement hose for the 944 power steering cooler to reservoir line. I found a cheaper better method of making this repair.
![]() The reservoir fitting end is nearly 1/2", the cooler end is 3/8"; which would normally mean that we need a trumpeted hose (a small, formed hose with an enlarged end) for the reservoir. But instead, I have bought mcmaster carr 3/8 ID hose # 5288k12 and cut four small slits in one end. Each slit is 1/8th inch deep (no more) at 3,6,9,12 o'clock around the hose end. I use wire cutters to make the tiny slits (just one cut per, not a "V" or anything fancy). ![]() Have your reservoir free from the car and look at the end of the 1/2" fitting. Use a rasp to even it up a bit with a little more shape of a cone (this might not be needed but it helps). Don't file off the barb, we need that. ![]() Put the slitted end of the hose under your hot water faucet for about a minute, this will soften it. Clamp the reservoir in a vice. Now force that 1/2" reservoir fitting down into the hose - you will have to lean on it. ![]() Clamp the hose and we are ready to re-install the reservoir. PS When installing the reservoir, rotate it so the neither hose gets too much heat from the exhaust (you might even re-use the OEM spiral wrap), the hose length is about 16" but start long and trim it once everything is aligned and you're ready to connect to the cooler. ? I'm sure many other hoses will work for this if McMaster-carr is not available. ![]() |
