This might be a long shot but I figured I'd give it a try. I currently have my electric fan controlled by a DC Controls FK35 fan controller. Last week I had an issue where my fans would not turn on. In order to toubleshoot the issue, I took off my fan shroud and attemped to pull out the radiator probe so that I could examine the fan controller that I have mounted in the shroud. When I tried pulling the probe out, the head of the probe ripped off and remains inside the radiator fins. It turned out that my issue with my fans was simply a loose connection at the fan power lead. So, I need to find a replacement temp probe that has the necessary connector to attach to the DC Control fan controller. I ordered one from DC Controls last week. I have been unable to get a response/confirmation from them in regards to my order. I want to get my car back on the road as soon as possible. Does anyone know of any other source for this type of probe?

I had great customer service from them back when I ordered the controller. However, since then, there have been a few "service" issues that have been noted on the forum. The delivery times are extremely slow and the customer service is non-existent. I'm not sure if this is now a "part-time" gig for the owners now or whatnot. I just don't want to have to wait for over a month for the probe to be shipped if I can get a replacement somewhere else. My other alternative is to get a new fan controller/relay kit from summit and pull out the DC Controls unit.

The driving season up here is short enough as it is :)

Is it a two wire thermocouple type probe or tube? The Flex-a-Lite 31147 kit is only around $26 or so. Maybe you can use the one out of it. If not, at least you'll have the new kit.

I honestly don't know what kind of probe it is. It has two wires that go into a connector that then connect to two pins on the DC Controls controller. The head of the probe is stuck between the fins of my radiator and I'm a bit hesitant to try to dig it out. Its been about 3 years since I originall installed it. I don't recall it being a metal tube type of probe, more like a plastic headed probe.

From what I see on their webpage for parts, it seems to just be a thermistor. If you can get the thermistor out of the fins you may be able to resolder the wires to it. If so, you can check it against the curve they have on their website if you have a multimeter. Just boil some water and put the thermistor in it while you check the ohm value. According to the chart they list, it should read about 4800 ohms (4.8k) in boiling water.

A TS104 is a type of thermistor. See if it looks like any at the link below. The temperature chart for these doesn't match what they list though.

Maybe you can take your radiator out and push the piece out from the front then get it put back together.

That might be worth a shot. Thanks for your help.
