connecting heater hose to heater ports at firewall

Powerman951 Thu Apr 21, 2016 9:44 am

There is short distance between back of my Ls2 engine and the heater ports on firewall of my late model 944. I am requesting photos of how your heater hose connects to the heater port on the firewall.

Thanks in Advance.

They let me rummage around in back of the autoparts store to find hoses with the right sizes and curves.

Rich thanks for your response. Is that your car? The picture reveals to me the hose being connected to the heater ports on the firewall without an elbow or anything else. My initial attempt to connect hose results in a crimpt hose at the 90 degree turn point.

Any comments would be helpful.

Those hoses actually have two nearly 90 degree bends. They bend toward the camera and then back away so it's hard to see, bad picture.

Yes, it's my '87 944 n-a.

To clarify your statement each hose has two 90 degree bends. A 90 degree bend on each end of the hose? Or two 90 degree bends near the end of a hose?

Yeah, each hose is an S shape with bends at each end.

There are 4 hoses in total with the heater control valve in the middle. So the two S bend hoses are at the firewall, then two hoses each with a single 90 degree bend at the end toward the water pump.

Clear?

Rich,

Did you ever rummage around in back of the autoparts store to find hoses with the right sizes and curves? If not I would appreciate it if you would and let me know what you find.

Thaks,

Dan

heater hose- napa auto 9820 and 9814
LS motor to Porsche radiator advance auto e71317 and d71500

I used a couple of the napa hoses to make it work but I also routed my hoses between the fender and the plastic inner fender well then I used two bulk head fittings to get back through the fender. In my application you don't see the heater hoses except for very short pieces

Correct me if I'm wrong Rich, but I think hose "19603" is a typo. Based on your pic further up in the thread and a bit of google image searching I think it's actually 19613.

I'm in the middle of a swap and was about to buy hoses when I noticed this and wanted to note it for anyone ends up at this thread like I did.

Yeah, I think you're right Rob. Oops! Hope this didn't steer anyone wrong. Edited to remove the part numbers as I'm now unsure.
