For my Daily Driver, I wall be switching to an electric fan. Should I use a controller (thermostat ) for the fan that mounts in the Coolant flow or one that uses an air / radiator probe? Pros / cons of each? Greg |

Coolant one may be more accurate, I have used the probe one too with the dial to set temp. A few people told me that the probe/dial weren't any good but mine worked fine. I know you will have that car for a long time so my thought would be the coolant sensor one. Snow Day?? |

Hi Greg. I am doing the same job, and I found a short pipe, designed to hold a temp sensor, in my local auto parts store. It is supposed to be mounted in the lower radiator hose, I have to cut away an appr. 1.5 inch part in the middle of the hose to make it fit. Some radiators also have fittings for a tempereture sensor in several locations, also near the outlet. That way you monitor the temperature of the already cooled water; no need to run the fan uneccesary. That is also the most common location used on modern engines. I also had a thread about the optimal water inlet temperature, and to follow up on that, I use sensors in several locations, for measurement reasons only. If you find that thread or others like it, you'll find many opinions on sensor placement. Olaf. |

I use the temp probe that's in the fins with my truck. It's mounted in the upper corner where the top hose is. If it's an adjustable one, you can set it where you want...................... |

This is what I did and wired in a switch to override the adjustable thermostat if needed.

I have the tube that mounts in the fins. It is up near the top, just as E's is. It seems to work fine, and is reliable. I did have one of these fail once, but they are only about $20 at Pep Boys. It was obvious it went bad as the fan simply would not come on when it got hot. When I bypassed it, the fan started. It is set up to supply a ground to the relay. The engine was fine, and did not boil over as long as I kept going, so I just drove to Pep boys and got a new one and put it on. I had wired it with spade connectors so changing it out was a 1 minute, no tools job. If you come up with one in the coolant flow, would you share that with us please? Sam |

Greg, Take a look at the pictures of mine. I have the temp switch mounted in the radiator. Just click on the red link below my name. Ceej put my wiring diagram in the Frequently Asked Questions - Electrical. Ted's Electric fan schematic with overide switch. It is a super simple setup. It has worked perfectly the last 7 years now. I did try running a Flex-I-lite probe system and that was not as accurate as wanted when running a 205 stat..... The controller burned up one day from moisture..... The screw in temp switch is basic and stable, very consistent. |
