Mount the relay under the hood in a convenient location as to the fan as possible. Notice: Don't use the teflon tape or thread compoud on the thermostat or adaptor. For proper operation, the thermostat must ground threough the threads to the engine and the engine must be ground. 2. Install thermostat into the head or intake manifold. Route the black wire to thermostat and cut to length. Crimp the red terminal onto the black wire and attach to thermostat. 3. Route and connect the red wire to the fan + terminal or power wire coming from the fan motor printed to electric fan. 4. Mount the circuit breaker provided in a convenient location as close as possible to whichever power source(battery or large terminal on the starter solenoid)you are using for the fan relay. 5. Cut to length and install using a small yellow ring terminal. With another small yellow ring terminal take the remaining red wire and connect the unused post on the circuit breaker to the battery source. This wire is printed to battery / constant hot. 6. Route the brown wire to the ignition switch or the fan switch whichever is more convenient. 265 283 305 307 327 350 383 400 396 402 427 454 472 502 260 289 302 351W 347 352 360 390 406 427 428 429 460 351C 351M 400M 273 318 340 360 361 383 400 413 426W 440 455 330 326 ENGINES Package Include:1 Set 175-185 degrees Cooling fan thermostat relay switch kit -Please check the compatiblity to make sure correct fitment before purchase. -Please allow 0.1-0.5cm difference due to manual measurement.

Nice Kit that Works as Described
Model: F-10041
I purchased this kit to resolve an issue on a friend’s 57 Thunderbird. The previous owner installed an electric fan and wired it direct to a basic plastic toggle switch. Full amps going through this cheap switch caused it to get very hot. I purchased this kit and rerouted the switch to operate the relay. Worked perfect and solved the problem. Nice diagram included is included to help wire it up. For the price this kit is a really good value. ... show more

been testing for a month and seems to be working perfectly
Model: F-10041
I bought this to match the new electric fan I installed on my Hot Rod. I really monitored it the 1st few times I ran the engine and it worked great. The original fan OEM was not up to the task, So with new electric fan and shroud it cools from 190 to 170 in a little over a minute, so I like the switch and it was easy to install. I ran the power wire to the switch and inside to my fuse box 20 minute job with the install of the temperature sensor. good price and it works finger crossed it lasts. ... show more

Solved an overheating problem on a 1937 Packard 120
Model: F-10041
This kit and a 16" electric fan solved a pesky overheating problem we had with our Packard 120 car when idling for extended periods of time. Kit is very easy to install and turns fan on and off at the exact temperatures stated. (185 on 175 off). I was able to screw the sensor directly to a NPT nipple on the water pump. Our beloved Packard 120 is now ready again for the Florida heat. Very pleased with purchase and ease of installation. ... show more

My son suggested trying this to solve my overheating problem. It’s good to have a smart son! The ECU was not turning on the fans even after all switches and relays were replaced. This gizmo worked flawlessly. I had to purchase an adapter to install in-line with a radiator hose because there was nowhere to mount the switch. If you do this, be sure to ground the adapter. Also, the brown wire needs power for this to work. I hooked it straight to the battery so the fan runs about 4 minutes after a hot shut down. ... show more

Decent Product with terrible instructions
Model: F-10041
I received my fan wiring kit today. Shipping was fast and the product was packaged well. Inside is the temperature sensor rated at 185/175 and has 3/8"NPT. The kit comes with a brass 1/2"NPT to 3/8"NPT reducer bushing for applications that require a 1/2" fitting. Also included is a 12vdc 30a short stop auto reset circuit breaker along with all of the electrical wire fittings needed to connect to the included 12vdc 60a 4-pin relay. The kit includes a pre-wired relay seat with 4 wires. Two of the wires are 12AWG colored in red while the other two are 16AWG colored in brown and black. Here is where I begin to have issues with this kit: It is wired incorrectly. The relay seat I received has the two red wires going to pins 30 and 87 which is correct. The black wire goes to pin 86 while the brown wire goes to pin 85. These two wires are backwards and here is why: Assuming a single fan connection, the user will want to wire a 4-pin relay in the following manner: * Pin 30 = {red wire} 12vdc battery (passing through the circuit breaker) * Pin 85 = {black wire} Ground (Connected to sensor as sensor grounds circuit when temp is reached) * Pin 86 = {brown wire} 12vdc Ignition * Pin 87 = {red wire} Fan Power If you wire your fan as shown above, you will be successful. In order to do this, you need to reverse the two wires in the relay seat. Alternatively, you can mark the ends of the wires using colored tape to keep track of ground and ignition. Personally, I would rewire it so future mechanics dont have to guess why a black ground wire is connected to the ignition switch circuit. Regardless, this kit will work but keep in mind that while the relay and wiring are rated for 12vdc 60a, the included circuit breaker is only 12vdc 30a. So if you wanted to wire two fans in parallel using this kit, you need to replace the circuit breaker with a higher rated one or just use a 60a inline fuse. Now lets talk about the instructions. The instructions are poorly written with broken english, misspellings and improper step references. Missing from the instructions is the crucial first step which is: DISCONNECT YOUR BATTERY NEGATIVE TERMINAL BEFORE INSTALLATION! On the back of the instructions is a wire diagram that is confusing because they placed the wire color labeling in odd places. The labeling itself is correct so long as you swap the black/brown wire at the relay seat. If you did not and you followed this diagram, the circuit would be NC and your fan would be on constantly then turn OFF when the temp sensor reached 185. In a nutshell: Literally toss the instructions into the recycle bin and wire the fan relay as explained above. You get a lot of quality hardware for the value so if you know what you are doing, this is a good kit to start out with. If you are going to wire two fans, personally I would use two relays, one for each fan, wired as indicated above. It is more reliable and will keep the relays cooler over time. Why risk overheating your engine? ... show more

Economical option. Only one sensor adapter option included.
Model: F-10041
The instructions could be a lot more explicit but this is an exceedingly simple relay, so it’s easy to look up better instructions and diagrams elsewhere. Note: it will only work when all the wires are connected properly. Brown wire must be connected to 12v power. Also, there’s only one sensor adapter provided, so be prepared to find whatever is necessary to your purpose. I’m a little concerned that the relay housing is not sealed, so I installed it with a more protective cover, and waterproof shrink seal connectors instead of the basic ones provided. We’ll see how it holds up. ... show more
