They might not have changed it, but it's probably not making a whine anyway. -- Catman MIB#14 SKoGA#6 TEAR#4 BOTAFOF#38 Apostle#21 COSOC#3 Tyger, Tyger Burning Bright (Remove rust to reply) 116 Giulietta 3.0l Sprint 1.7 GTV TS GT 3.2 V6 Triumph Sprint ST 1050: It's blue, see. www.cuore-sportivo.co.uk |

The part I'm talking about is the Air-con compressor - the pipes coming in and out must be the coolant pipes. This is at the front of the engine and is on the right of the above image. The alternator is behind the engine and low down and hard to get to. Just for my own sanity - where is the water pump? |

It's not really a pump in the way I think you're imagining it. It's an impeller that sits *in* the water jacket and forces the water to circulate. http://www.aresespares.com.au/images...p%20TS%202.jpg The impeller is inserted into the water jacket and seals using the plate on which it is mounted. It is driven by the cambelt to the drive pully that the item is sitting on in that photo. The whole lot bolts into the front of the engine block In any event, you're looking at lobbing it at a garage. I'm afraid. If the aircon compressor is shot, then it needs the gas removing (and capturing) then the item replaced, and then the system will need re-gassing. If it *is* the waterpump (damned sure it's not) then it's a full cambelt change. You could just bring it forward from October I spose. -- Catman MIB#14 SKoGA#6 TEAR#4 BOTAFOF#38 Apostle#21 COSOC#3 Tyger, Tyger Burning Bright (Remove rust to reply) 116 Giulietta 3.0l Sprint 1.7 GTV TS GT 3.2 V6 Triumph Sprint ST 1050: It's blue, see. www.cuore-sportivo.co.uk |
