Radiator hose routing on 912iS (left side)

[efwd]

I believe I rectified the contact on the temp probe by securing the oil line with clamps or wire ties or something. Wire ties on the engine mount is ill advised from what I understand so I wrap sillicone self adhesive tape around the tubes first. Gives a wire tie something to grip on to.

I’m running into this same issue. I’d like to mount it as some have between the exhaust and the ring mount but if I bend the Rotax hose in that way it runs against the temp sensor.

I found a pre-bent hose that might work at the auto parts store. I’m hesitant for a couple reasons...the main one being how far back I have to cut the Rotax hose to make it work.

Thoughts on using a pre formed auto hose?

Seems there are several of us near the same stage of the build. I'm just completing the 912is wiring - the individual wires that is. I wrapped up this evening's work after managing to get the HIC connectors fed through the firewall. I'll suggest feeding these large connectors and harnesses before running individual wires such as the Start / Backup Battery switch wires. Eventually the wires will be neatly bundled but, at this point, it's just a jumble of wires.

Nice to have a heads up on the radiator hose before I get to that point.

Carl, I bought a heat shield sleeve from LEAF. I think I bought 12 inches and sleeved the radiator hose from the heater hose intersection toward the top of the engine. I highly recommend protecting the hose. I had an issue during taxi tests, and burned a hole in the hose and had to replace it. This hose is easy to remove, but very difficult to get it back on. A sleeve may be easier installed than trying to wrap the hose in that tight space.

I miss cut the fire sleeve when installing the high pressure fuel lines. A local industrial supply was a convenient place to buy a replacement and, since the stuff wasn't expensive, I casually tossed the cut pieces and started over. Today I noticed the "aircraft grade" numbers on the fire sleeve at AS&S and realized the local product wasn't the right stuff. So AS&S got an order for a few feet of fire sleeve (~$15/ft), some thermal wrap and a thermal mat to protect the lower cowling from the nearby exhaust. The high pressure fuel lines aren't going to simply slip off the fittings so I also purchased a length of high quality, Gates Barricade high pressure hose.

Really appreciate the information on this thread.

I'm finally returning to installation of the oil cooler and radiator hoses on a 912iS with oil cooler. One of the first steps with the 912iS is to move the oil return port to the bottom, pilot side of the engine. Instructions and drawings in the Oil Cooler Installation section clearly show the return hose running from the top of the oil reservoir to a return line located at the front of the engine. After lots of head scratching, I'm concluding the Oil Cooler plumbing instructions are "general" and for the 912iS, the return line goes to the fitting on the bottom of the engine. Any comments?

Here's how I've started mine. Oil line will be attached to help hold everything in place.

Where do you buy the shiny insulation wrap shown in Joe's post #16? And how is it secured to the hoses.

I also be picking up a length of the orange 3/4" fireshield. Are only the fuel and oil lines covered?

As you have undoubtedly heard, yesterday was not a good day to fly (VFR) here in Southern CA. I stayed home. Sorry Carl.

Understood Eddie and thanks for the feedback Dustin.
