I'm recently getting a few problems with my H22A swap into 96 civic Dx hatch. 1. The radiator fan is not working. 2. Radiator hose are getting really hot quick. the bottom hose seem to be not getting any coolant at all, just empty and very hot. My coolant in the coolant tank is boiling. 3. When I drive around, at 3k to 5k rpm, it seems to be very slow, then it'll just pick up and go. 4. Engine seem to be overheating alot. It has gone to the 2nd mark past the middle one I've replace the waterpump, and the thermostate. I've run out of ideas and options. I dont want to keep replacing parts and not finding the cause. A few friends of mine has suggested to replace the whole radiator unit. I've been thinking if it will be possible to fit a bigger radiator. The car has some mods. AEM cold air intake, Complete MSD ignition system, AEM fuel rail and regulater and fuel injectors.
