My car- 76 914 2.0 with D-Jet, essentially stock heater, with SSI HE backdate to remove the emissions stuff and an extractor style muffler/exhaust.
I've got the single outlet engine bay heater fan installed and functioning electrically, but I am on my second used one and this one has bad bearings too. Not fun. What I am wondering is if anyone has tried deleting the electric fan from the duct system and just running with the engine fan? I did this on my 76 912E running a set of 411 heat exchangers and had decent success. This is common on the 911s and 912Es, but this is a different setup entirely and I do not want to assume anything. I know it will work theoretically, but wanted to know if anyone has actually done this and if the airflow is sufficient for driving in warmer climates. Right now the coldest I would likely see would be around 30 degrees. I know that the ariflow is reduced... that it changes with engine speed, etc.... The other option is to rebush the fan. I looked at it and you can see the wear in the bearing on the end nearest the fan impeller on both which allows the impeller to rub on the housing. Has anyone done a successful DIY repair, or found a suitable functional replacement? |
