answer to this is no! lol the head warps!!! i ran low on coolant(pinched thermostat seal) and overheated causing the cylinder head to warp!!! i was going to replace the water pump at the same time as doing all the other work but there was a massive 8 week waiting list on the part from ford. car is back on the road now, all sorted as the mechanics stripped and checked the water pump on there and said it seems ok. i hate not having a temperature gauge. i think the graham goode one is soooo overpriced. are there any other options?
