It's in the front, passenger-side corner of the engine compartment. As you face the engine, it's just to the left of the battery. It hangs from a mounting bracket held by one screw. I have no idea how to find the temperature switch that turns the relay on.


The fan Relay switch or sensor is located on the thermostat housing. Follow the lower radiator hose to the engine. Inside the where the hose connects to is where you will find the the thermostat, you will also find a sensor connected to this unit. It has two wires coming out and can be removed by pulling on the bracket. If you connect a paperclip or wire to both female connections (on the wire side not the sensor) you bypass the sensor and the fan will come on automatically.

The AC system on that year was actually dealer install only, Honda didn't ship any with A/C. To answer your question, yes. The cooling fan relay is located behind the passenger headlight next to the air filter box. It should be right next to the passenger side engine bay ground point.

an accord is a big car and putting a 1.6 out of a crx would kinda be a little on the stupid side(no offence) it would probably run like a RC car

Almost all parts will interchange as they have the same chassis and series of motor.

The Honda CRX features a cable type clutch and therefore does not have fluid. The CRX Del Sol however features a hydraulic assembly and does.

no, because there is no such thing as a 1999 CRX
