I am working on a 1988 Honda Accord (2lt, injected, A-series engine) that has been sitting a while. I am getting an issue with it overheating (after about 20 mins idling).
The thermofans kick on at the right time - when the temperature gauge reaches about half way. They will run for about 20 seconds, then switch off, then come on again maybe 3 mins later. Meanwhile the temperature just creeps up and up.
I have done the following:
- Flushed cooling system (lots of gunk in there)
- Replaced thermostat
- Replaced water pump
- Replaced radiator cap
Radiator visual appears fine, but could this mean it's toast? Anything else this could be?
