my engine (3.5v8 rover)keeps over heating in traffic/siting at ideal.the rad is pleanty big enough.(24inches wide X 18inches down)ive 2 9inch fans fitted to the front pulling air from the front through the rad.it has a new water pump and thermostat and no leaks.any ideas would be appreciated ,thank you.
as caddyman says could be air lock that would coincide with mr pop and the heater. it may still be the rad though, the size may be enough but it may not have the capacity as i had a cooling problem a while back and had to get my rad re-cored they doubled the size of the core now its a treat
