1986-1987 Buick Turbo Regal -
DUAL FAN CONVERSION KIT and
CUSTOM-MADE PLUG-AND-PLAY HARNESS

We offer three options to upgrade the factory single electric fan on a 1986-1987 Turbo Regal to a dual fan format. Each fan has a 12" diameter sweep. There is no clearance issues between the radiator and the factory intercooler shroud. The unit is 3-1/2" deep. The overall width of the unit is 26" and the length is 16".

The complete kit includes a brand new Intrepid dual fan and a custom-made plug-and-play harness. This harness is specific to the Intrepid dual fan.

One of the beneficial upgrades to make to provide better cooling is to install a dual fan set up to replace the 25+-year-old single electric fan. The factory Buick fan relay cannot safely sustain the full load of dual electric fans. That is why it's advisable to install a supplemental relay system.

This custom-made plug-and-play harness is specially designed to make the conversion easy. This plug-and-play harness consists of two sealed relays. The relays are both energized by the factory fan relay in your car, reducing the circuit load on the factory relay and permitting full coolant fan control without the risk of overload. The fans are both powered at high speed when cooling is commanded via factory low speed coolant fan control through the ECM.

This has the delay relay, so the second fan is delayed.

This kit plugs into the factory fan connector, unlike other harnesses that require you to cut off the factory connector. The factory connector is entirely reliable and should not be cut.

The plug-and-play harness is made in the U.S.A. by Caspers Electronics and comes with easy-to-follow directions with photos.

We offer 3 options. The first option is for the entire conversion kit, which includes a new Dodge Intrepid dual fan kit and the special custom-made plug-and-play harness. The second option is for the dual fan only. The last option is just for the custom-made plug-and-play harness.

NOTE - We recommend installation be done by a qualified mechanic.

IMPORTANT NOTE - You have to custom make brackets to mount the dual fan housing so you can secure this to the 1986-1987 Turbo Regal radiator core support at the top and bottom. You also have to cut off the original mounting tabs on the side of this dual fan housing since they do not get used. There is a link on the Turbo Buick forum with photos that shows what you have to do. Basically you have to cut off the 2 plastic mounting tabs on both sides of the housing and fabricate some small piece of angle iron to secure it to the original top brackets and the bracket at the bottom of the core support.

This dual fan set up is for a Dodge Intrepid and is the one that most 1986-1987 Turbo Regal owners have used for this modification. It is also the one that will plug into the custom-made plug-and-play harness we offer. Be sure to click on the link below so you fully understand what you need to do to modify the dual fan housing to attach to the radiator bracket and core support.

NOTE - According to John Spina, who makes this plug-and-play harness for the dual fan set up, it's important to make sure you do not have any other issues with the factory connector or the contacts, since it can cause it to overheat. If it runs all the time, you could very well have a defective fan relay. The dual fan is NOT a cure all if you have an existing issue as noted.

It is not normal for the wires to get too hot. However, they should be warm. Both fans are running thru the OEM connector ground. If the original connector is defective or has poor contacts, the part will overheat.

For the fans to run continuously, there may be another issue with the factory wiring, and/or a defective fan relay or connector.

Many times, a car owner has an issue with a function on the car, and believes that upgrading will solve the issue, which may not be the case.
