So I just boosted my 92 CX with a 98 B18. My car has an overheating problem. When driving the car the temp reaches in between 192-194. When you stop (with heater on) it will start to drop back down. I changed the thermo, bled the system. I am going to change the radiator tomorrow (hopefully). Does anyone have any other suggestions i should look for. It seems also that once i get on the freeway it jumps up quicker. ANY HELP PLEASE!!!!

 

Any leaks? Could be pump. Honda water pumps are not really known for failing but there's always a possibility.

 

Double sealed thermostat?
boosted? (swap? turbo??)
98 b18...vtec, non vtec?
if you didn't replace the radiator along with your swap, you should probably buy the corresponding OEM replacement, for the motor that is.

 

could be your radiator... as soon as i went from 1.5 8 valve to 1.6 16 valve it started getting hot alot... i replaced everything form hoses to waterpump to thermostat to thermoswitches.. nothing.. replaced the single row cx radiator with an aluminum autozone 2 row... its good to go

 

boosted=turbo on my b18c1 sorry i realized i didn't give all info. i am going to change radiators so hopefully that will fix it
