b18 obd1 swap fan/overheating issue?

[accordwolf]

Just finished up my swap and the fan on the radiator refuses to turn on, so i'm having overheating issues. fan worked fine before the swap and i used my multimeter to check and i have power all the way up to the fan itself. think my fan just randomly went bad or is there something else i'm missing here?

Put voltage directly to the fan and see if it works. If it does than you can rule it out.

Confirmed it works when i hard wire it directly to the battery, any other ideas? I was thinking wiring a switch to the dash and wiring it directly might be easier than tracking down a problem in the wiring but I'm not sure if that would cause me whoas later on?

I've hardwired secondary fans through a switch before. No issues.

But iit should be something simple. Polarity reversed? What car and what harness.

Lx what? Accord?

are you saying you have a b18 in a accord? and theres a sensor on the thermostat housing and one on the housing where the top radiator hose goes into the motor, one is your temp gauge and the other is your fan switch take them off one at a time and put a paper clip in the plug to bypass. if it turns on you know its just that sensor and go to the jy and get a few. if its not that start checking if any wires are messed up. this is usually just a wiring mistake though and im pretty sure its the one where the top rad hose comes in.

You may have wired it wrong. This happen to a friend of mine. He wired the positive to the negative and the negative to the positve. By doing this the fans were pushing hot air onto the radiator instead of pulling cold air from the front of the car thru the radiator. This caused his engine to overheat.

i think hes saying he put in a b18 fan. if he put in a b18 engine he needs to show pics first

id say just wire it to a switch that way if the engine runs hot and for some reason the fan doesnt turn on automatically you can just flip it on.

upon further research he just has an f22a

Post up some pictures of your engines and whats under your hoods. I'm trying to get some ideas and inspiration. Here is a picture of mine. All stock right now except I painted the cover over my headers to match the body.

I found an F23a motor from a 2000 accord on craigslist for $400 bucks on craigslist so I'm thinking about doing that swap, I'm going to look at the motor tommorow.

Was this issue ever resolved?

...and how about some photo evidence of this swap?

That post was from December of last year.
