Hey guys. Got a 92 Civic Breeze.

Have had an issue with overheating from the day since i bought it. The problem only occured when either on the freeway doing 80-100km/h or under hard driving. Temperature steadily raised higher from it's original spot just under halfway on the gauge.

Pulled over and checked it, and there was coolant spilling out of the overflow bottle. Temperature dropped back down at idle, so merged back onto freeway. Heated up again, so i put the car into "limp home mode", but found that by turning the climate control over to heater, the car didn't overheat anymore. And it didn't overheat since, jsut by keeping the heater selected(not even running the fan, just having it on the far right on the temp slide).

So from this i figured it must be a blocked radiator, or somewhere in the system. Due to the fact the heater circuit was enough for the car to maintain temp and that the car wasn't losing coolant. Ordered a new radiator, cap, hoses and thermostat. Radiator was an ASI item off ebay and fitted in perfectly.

So just fitted that today. And after bleeding the system up, all seemed good. Temp gauge was sitting at about 1/3. Took it for a drive and came home. All good. Then let it idle and flicked the climate over to the cold setting. Was fine for a while, but then gradually started to climb over the 1/2 mark. Was watching for the fan and it didn't seem to cut in until about 1/2-2/3 of the gauge.

So now i'm wondering where the issue could lie. I haven't taken it on the freeway yet, will be later tonight. So will report back tommorow on anything else i've picked up on. Any ideas?

Sorry for being vague with temperature readings, only have the gauge to go off.
