I got in my car this morning to go to work and turned on the blower to clear the windscreen. After a while I realised that while the blower was working that there was no heat coming through. After work driving home the needle on the temparture gauge went to the far right, I stopped the car at a garage and waited for things to cool down, I added some water to the radiator, I was surprised that it only took half a litre or so. When I got back in the car I found that the heater worked this time. I noticed when I got out of the car that there was water dripping from underneath the car - this seems to originate from the timing belt area.
Is this the water pump? Can I drive my car? Is changing a water pump a job for an expert? I'm reasonably compentent with a spanner - is there somewhere that shows me how to do it (other than a Hayners manual)?
Thanks
