Overheating Problems? Run cooler always!!
Here's a little trick i stumbled upon when my was overheating really bad. I live in frickin hot ass Las Vegas, so when your car starts to overheat...it's some serious s**t!
The cause for my overheating problem wasnt a bad t-stat or radiator, but my engine fan. It just wasnt coming on. My car overheated when i had my d16z6 and it overheated when i got my b16. So i knew it wasnt the 'stat and the radiator is fairly new, so there u have it. This little trick should work for any honda provided you make the proper adjustments as needed. Your car will run cooler guaranteed. And at around $10-$15 bucks, you cant beat that. Ok enough babble heres how you do it.
Start by locating the wiring harness that hooks up to your radiator. On my civic it was on the very bottom towards the passenger side. It has a green clip.
Cut the wires to the harness (making sure you leave a few inches) but dont take the clip off the fan. Strip the wires a quarter inch. Take some wire you have laying around and make jumper cables directly from the battery to find out which wire on the fan is positive and which is negative. The fan should turn on with the key in the ignition but car off (safety reasons). Splice together a new peace of wire (about 2.5 ft long) using butt connectors to the ground wire on the harness and the other end will be grounded to the chassis.
The positive side of the wire you will have to go through the firewall. So butt a peace of wire to that end(around 5ft long) and set aside for now.
Next you will have to make another wire for constant power. I spliced mine into the green vtec wire, but if you dont have vtec...you can use any other source of power that is activated with the car in the on position.
The wire that you spliced into the constant power will need to be around 4-5 ft long depending on what source you used.
The next step is to drill a hole about 1/4" into your firewall (i know i know, but you have to do it.) The best place to drill is right above the hole where your throttle cable is. Note: do not attempt to just use the throttle cable hole! It does not work!!! I tried it and the throttle position was fukt....all the time. It will idle at 4k rmp. just dont do it.
After your hole is drilled, feed the positive fan wire (from earlier) and the constant power wire. Make sure you use female speaker style connectors. (well it depends on the switch you bought).
You will have to decide where you want your switch to be. I placed mine by the shifter console. Anyways once you have decided, take your two wires and hook them up to your switch. Note: The positive wire from the fan is called "lead" and the constant is just "power". Once those two wires are hooked up, you will have to ground this switch to the chassis.Note: this explanation applies to the "light up" switches. You know the kind that have a little LED light in them. If the switch you purchase does not light up, the some of this info will not apply to you. Im sure you can also use toggle type switches.
The beauty of this mod is that you can either choose to have the fan on at all times (like i do here in vegas)
or turn it off at your will. It is a known fact that the cooler your engine is, the better your car runs. Anyways hope this helps. Pm me with questions.
