Sorry but I cannot see the little Bosch pump doing much to help the main mechanical pump. If you have overheating problems they should be addressed. Adding a small pump is not a solution. IMHO.

Sat in traffic for an hour yesterday on a hot motorwayand had to leave the engine running (duff battery) temp was fine ,If i was going to bin my water pump it would be because of the jackshaft meshing issues and the pump over run optionand not its pumping performance.

ok guys im gonna use the pump as a heater one in conjuction with the main pump. now my question is, on the water pump at the front of the engine, does it pump towards the heater rad or does it suck. what i guess im saying is what way does the water flow form the water pump?

The flow is from the head through the heater to the bypass - you may need to ballast the pump to avoid overcooling one head - some people are modifying the other transfer housing so that both heads feed the heater via a Y piece

so the pump end is sucking?

You are thinking about it the wrong way - on a standard cooling system it is being pushed from the head, round the heater and returned to the water pump housing - it's a recirculating system for heater only.

So if you are replacing the main pump, you need the heater assist pump to suck from the heads - remembering if the heater control is set to cold, you have a problem coz the pump is being stalled and it could get a bit noisy.....

sorry im just being thick, but that makes no sense to me wat so ever:X
surley the water has to come form the main rad or else it wouldnt get hot at all.
so im thinking that if i use the pump to push the water around quicker it ll cool down quicker,,,,,no?

So doesn't the heater on your car work before the thermostat opens and radiator flow starts?

Mine does.

The pump pushes the coolant around the block, heads and inlet mainfold, then when the stat is closed it returns the the pump via the bypass system - then when the stat opens it takes the normal path through the rad round to the pump inlet....

If you are not sure maybe it's best just to make sure your standard system is good and forget electric cooling
