mk punto 1.2 8v
first a little tail of woe to set the scene.
The misses hit a small wall at low speed with the corner of the drivers side bumper. This somehow moved the radiator so that the bottom ns mounting peg snapped taking some of the radiator with, this promptly dumped all the coolent on the floor but the misses didn't realise, not even when the heater didn't work, so she drove it some 15 miles home. She said it cut out once just before she got home but started ok.
Now I have changed the radiator and the engine did not appear to have suffered any major damage, as it started and ran ok, however after a little trip the heater still refused to work and although the radiator cooling fan was on the radiator was cold.
I bleed the system but still no heat and a cold radiator.
Having disconnected the top hose and turning over the engine there seems to be no water flow at all. Is it possible the water pump has had it, looking at the one in the haynes manual the vanes appear to be plastic so assume could have been damaged or melted !! How likely is this??
Also if I have to change the pump I will change the timing belt however the haynes manual says that it's procedure is only a guide and the tension must be checked by a fiat dealer. Is this true as I have changed many timing belts on various cars and have never had any problems.
