My external oil cooler fan stopped working. Does anyone know what this is or where to start?
PO put the cooler and fan on and it mysteriously stopped working. I checked the 2 fuses that are attached to wires that attach to this, both good (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) I have the car on stands letting it cool off before I start the troubleshooting. Can I just bypass this box and have it run all the time with the car on? It's getting damn hot here anyway, atleast for the summer. Luke D Attached image(s)

The circled wire goes into the box.

What I don't understand is why it takes 5 wires plus the gray wire which must be some sort of temp sensor since it goes into the fins of the cooler. So 6 wires to run a fan??

Looks like my system is very similar to the pelican tech article. I know have a better understanding of what he has done. Won't know for sure until I crawl under there with flash light

It's a thermostat. Do a google search for:
thermostat 70085 and you'll find it. Demick |

There are 2 lines comming from just above the oil filter. Looks like a sandwich adapter that screws onto teh factory filter location and the filter screws onto that. They go straight to the cooler unlike that pelican article.

!! UPDATE !!
Problem fixed. I traced all the wires and found the main + lead barely hanging on by a thread. Re-crimped and fan comes on at 200F. One thing I noticed is the fan is pulling air down, is this correct? Second, I think I am going to have to put in a relay to power the fan cause I doubt that the thermostat is going to last with the main power running through it. Third, I notice that if I post a new thread that it motivates me to fix the problem and I end up answering my own questions LMFAO (IMG:http://www.914world.com/bbs2/html/emoticons/chair.gif) Thanks for the motivation dear 914club (IMG:http://www.914world.com/bbs2/html/emoticons/wub.gif) Luke D |

'correct' is going to be relative in this case. your cooler is located behind the engine, next to the transmission, and above the heat exchanger. you definitely do NOT want to be blowing hot air off the heat exchanger up into the cooler, so down is better. but there's not much room above the cooler for air to enter; that's got to be hurting your efficiency still more. longer spacers, maybe? to address the "how many wires does it take" question in the thread, 6 seems right: power and ground in, two leads from the thermostat, + and - to the fan motor. |
