i got a 1993 honda civic vx hatch with gsr swap.
My radiator fan is always on when the car is started. and my temp gauge is not working correctly. it sometime stay under cold for a long time and sometime it goes up a little? and vtec is on and off. does anyone know how to re-wire it back to like stock. cause the guy who did my swap sucks. thanks please help.

 

bump. got the same problem.

 

does anyone else have the same promblem or know how to trouble shoot the problem.

 

If it needs to be rewired then get the harness at the junkyard or somthing and start over.

Going over other peoples work can be more work then starting fresh.

 

have you done the normal troubleshooting for temperature issues?

start here http://www.tegger.com/hondafaq...x.htm

also you should check the faq, there is a walk through for the swap.
also did you use an obd1 ecu?

 

I don't know if this help but when my radiator fan doesn't turn on and my lower hose was a little too cool. My temp gauge will sometime goes up to H and when I rev it up.. it goes down to normal and it keep doing that. I also jump the sensor plug to keep the fan on but it didn't help. So i found out that my thermostat wasn't opening so I changed my thermostat and my problem was fix. Maybe your not running a thermostat? and your always on open loop? hope this might help
