water pump, when fitted can you still shift the impellor by hand, or can it only move by pulley and fan belt with fan fitted to harmonic balancer |

It should spin easily by hand without the pulley or fan. |

Siezed bearing, engine sitting for long time and coolant has solidified and locked it up, or plastic fan has deformed and is rubbing on timing chain breather - I've seen all of those before. Those would be more normal - not sure if say fitting a 1275 pump to an 850 would lock it though. Whats yours doing? new or old and is it tight or locked completely? |

when i fitted mine i was advised to check if it spun after install as you sometimes have to get a file out to enable it to spin freely lucky for me mine just worked i have a 1275 |

I can not spin it by hand, I just bought the engine from someone who said it has a brand new water pump installed. There is coolant in it from previous owner, I have just fitted a heater blanking plate, can see coolant in it no fan fitted, just the pulley, and it is not moving. |

can you store the engine without coolant to stop this happening again? just ordered a new pump. |

you probably have the large impellor type water pump fitted often they need a couple of gaskets behind, or grind out the offending section of the water jacket/wall behind the pump where it clashes with the impellor typical situation of someone "thinking" they`re fitting a better pump but not recognising the need to make sure the impellor clears the number one bore/wall/jacket easy fix tho & better off with the large impellor pump anyways |

the bolts are to long through the pulley touching the pump even with the fan on |

Should the fan have a spacer too explaining why the bolts are too long? |
