all is fine when i am driving the car in low revs up to 4-5k
however once driven hard for a couple minutes and the heat goes up
to the 3rd line it just wont cool down when driven at 3-3.5k revs
to try cooling it .
the radiator fan is working perfectly normal and the thermostat is
opening fine as i can monitor the temps of the water going in to the
rad from an extra sensor and gauge combo .
i thought the radiator was not up to the job first
but it cools the rad down when stuck at lights etc and
the temps go up to 3 rd line ,it drops it to 2.5 line mark after a
20 seconds etc .
so it leaves me with the water pump , are these known to lock
up and let the belt slip over the pulley at all ?
i have a non p/s belt setup btw and the belt only drives
the alternator and water pump .
