I've got an '88 2lt injected Accord.
It had not been running a while and had a problem with overheating and surging.
I've replaced the water pump, which had a bad bearing, and attempted to bleed air from the cooling system. I undid the bleed cap near the thermostat housing and filled the radiator until coolant come out. I then started the car and brought it up to temperature. It was there that it started surging - idle rising and falling. The temp gauge also started to rise to about 2/3rds but the thermo fans did not kick in.
The old coolant is in pretty poor condition - very, very rusty brown - so I plan to do a full cleanse of the system, but I was just worried about this issue with the fans not kicking in and the engine surging (checked fan fuses and they're ok).
Would anyone know where I should start with trying to figure this out? Many thanks!
