overheating when idleing
have replaced thermostat, waterpump, radiator, and clutch fan and it still overheats when idleing in traffic
Try doing a good cooling system flush the cooling ports in the engine block maybe clogged. Prestone Super Flush is really good. If thermostat is easy to get to would remove before doing flush then reinstall afterwards.
Thanks Mark, I haven't tried that yet.
