Xc90 D5 coolant leak, pipes ok, fluid on block
Hello all,
I wonder if anyone can help? Our 54 plate D5 has started loosing coolant. Been ok up until last week then it started dropping and now using about half a pint every 3 days. Pipes look fine but I have noticed blue coolant low down on the engine block. I'm not expert but it looks too for the head gasket. It seems to be weeping from the gasket but why is coolant down by the sump? Any ideas? Many thanks, Sam |

Firstly, remove the timing cover and check all around the coolant pump which should be bone dry.

Just what I was thinking, my money is on water pump - any water loss in cars I have owned with head gasket problems has always been via the cylinders so have seen an engine leaking water from a head gasket down the block.
Could it be a leaking core plug? |

Thanks.
I will check tonight. Any idea of cost of water pump replacement? Is it a big job? Sam |

If it is the waterpump ( quite unusual on a Volvo if original ). you may as well do the whole cambelt and auxiliary belt as well because the waterpump is driven by the cambelt.
Unless it has all been changed VERY recently, it makes sense to kill two birds with one stone . If you are handy with the spanners then all of this is very DIY doable.

Sounds promising. Can you do it without lifting the car? Only have a drive and won't work underneath on jacks. I could buy axle stands I suppose if it helps.
