🔧 Dorman 902-303 Engine Cooling Fan Relay Kit - Enhanced Performance for Select Models, in Sleek Black Review

Let me start by saying that it works. My only complaint is the cheap wire harness/connector that comes with the relay itself. The wires are very slick and where I worked was 90+ and the wire slipped right through my hand when trying to strip the end causing the metal pin to slip out of the plastic connector and cut my hand. Luckily the stylus went back into the plastic socket and worked fine. Nice to see they contain what I think is thermal paste. However, I had some spare CPU thermal paste for

The wiring harness is a bit stiff due to the small number of strands of wire used. The cable itself is an OEM dimension so it can handle the current like an OEM wire harness, it just isn't as flexible. The installation itself was easy. I soldered my connections instead of using the supplied compression fitting. If you're buying this for a 99-04 Grand Cherokee, make it easy on yourself and google how to cut the plastic under the headlight so you don't have to remove the bumper and all to get the

One of the most common overheating problems on 1999-2004 Jeep Grand Cherokees is the fan relay. Installation was easy enough and I was happy that it came with lots of extras like thermal paste, wiring harness etc. The feeling went away very quickly, within 3 days the relay was defective! Much worse than OEM. You see, when the factory version fails, the machine just overheats a little, about 20 degrees more than it should. With this relay, either the fan stays on all the time even when the…

Well the price was attractive and I've generally had good luck with Dorman parts. My experience wasn't that good this time. After 3 months the relay failed and the coolant temperature was fixed at idle in the parking lot (fortunately not on the highway). The car is a 2000 Dodge Grand Caravan. At first I couldn't believe that the part would break so quickly, especially since I used really good thermal compound (sold separately) underneath it. But once I ruled out everything but the computer, I…

If you are looking for a fan relay for a 2004 Grand Cherokee WJ, everything will point you to this part. At least I didn't have that and there are two relays in the fuse box on the passenger side of the engine bay (high and low). I had Tyco relays part numbers 04848879AA 72472M. After a long search I finally found an ad on the internet that Mopar 4727370AA replaced the originals. I bought these (from Revain) and they are a great replacement, overall slightly smaller than the original but the…

I have a 1998 Dodge Grand Caravan and this one works perfectly. I've bought all the others from Revain and even one from O'Reilly and none of them worked properly. I was about to go to the dealer and then found this one with a new plug although mine looked fine. Tightened and no problems so far after about a thousand miles. The rest burned out in 15-20 minutes. My original fan just kept running even when it was off, so I had to unplug the battery to keep it from draining my battery. Others only

When my girlfriend's Grand Cherokee overheated we assumed the thermostat was stuck so I bought a new thermostat and installed it. Next the fan assembly needed to be tested by connecting a few wires between the battery and the fan connector. The fan worked! Enter this part. Ordered and delivered two days later. I removed the headlight as shown in the YouTube video and found that the original has been replaced at least once. Dorman recommends replacing the wire harness with a new one, and the old
