I have an '02 sedan and I got an H23a swap done with 5spd. I recently got a tune up - new belts, antifreeze, oil change, etc. I also just replaced the thermostat and radiator cap due to this issue, but unfortunately it hasn't fixed it. The issue is that the fans aren't coming on and the antifreeze is going in to the overflow res before the fans ever come on. I have the stock radiator and radiator cap for the F23. I'm thinking that maybe there is a temperature discrepancy with the H23's running temp. But I haven't been able to find an exact answer anywhere if there is a significant running temp difference between the engines. The thermostat I got is for a 2000 prelude, it was most like the old one that came with the H23. If I have the right idea on what the fan switch is I checked that its connected,but I may be wrong - I assumed it was the wire connected directly to the thermostat housing. Any ideas or advice? thanks for reading
