Hi all, new poster here.
I am fixing up an ’88 Accord (2lt, injected) that had been sitting a long time. I am having an issue with it overheating. When testing while idling stationary, the thermofans kick on when the temp gauge reaches about half way but they only stay on for short bursts of 20 secs or so. They will come on again after about 2 or so mins. Meanwhile the temperature creeps up and up.
It feels (to my uneducated self) that the fans should stay on longer, but I’ve never worked on many cars like this so don’t really know.
– flushed the cooling system (there was a lot of gunk in there) and bled the air from it
– replaced the thermostat
– replaced the water pump (old one had bad bearing)
– replaced radiator cap
Other things to note that might mean something to someone:
– I had the dreaded bouncing idle issue, though this has all but disappeared since I bled air from the cooling system. However, during a 20 min idling test it did drop and resume 4 isolated times.
– The cooling system was absolutely filthy. It took about 12 flushes to get the water coming out clean.
– Radiator appears fine visually – no damage or rust from the outside.
– Idle is high. Starts at about 1000rpm and increases to about 1300 – 1500rpm when warmed up.
Is my radiator toast? IAC valve? Anything else I should look for?
Many thanks in advance!
