Electric radiator fan conversion
Hi !
I would like to use an electric fan for the radiator and remove the mechanical one. I would save some hp i thought to a volvo 850 fan and shroud. could you help me telling me what parts do i need to harvest ? i know there are relay and sensors but i'm not familiar with this advanced technology (hey, i have a D24..) thanks guys !

This is something I've thought about doing but didn't know if there would be much gain. The viscous fan really does howl like hell though, especially at higher revs!

If i remember correctly 850 had dual-speed fan, and you had to do some fab to wires coming from fan,
since there was relays and so on on fan itself. Once again, i dont copy if it was on 850 fan. But what you need, is temp-sensor, either with one or two different "switch-points". An relay, fuseholder, some wire of course, and connectors. And fan. On this PC which is on loan sicne mine is broken, sint any kind of drawing program, so i cant draw you an electric schedule how to connect, so sorry for that. |

As i understood you can avoid to lost several hp and make a lot of less noise like you said at high rpm. all efficient cars have those goodies nowadays to avoid wasted hp like the electric water pump or regulated volume oil pump. But often it's quite ridiculous because they have an AC system....

Yep
that's true and not stupid at all. Now i'm installing a d24 NA prior to finish the tic . so the airflow is not a problem. anyway i prefer not to lost hp with a fan for the NA because there are not a lot yet... and i want to speed up the warming up (with an oil cooler ) and the electric fan wich do not constantly cool down the engine bay particularly in winter. Thanks for this useful comment

Michaelovitch,
You may want to look at this product. http://www.x-eng.co.uk/X-Fan.asp I use it with a two speed Volvo fan and relay from a 92 745 turbo. I have is set so that the low speed runs with the a/c otherwise the temperature switch turns on the low or high fan speed based on coolant temp. The instructions say to put it in the lower radiator hose. There are other ways to do it but this is clean and tried and tested. I have it on a 300tdi but I'm also going to put it on my D24T converted from gas and get rid of the viscous clutch and fan. Bon chance, Steve PS I appreciate your postings on the Bosch VE pump etc on Scribd. Really good stuff. |
