Hi,
I am not very Engine/Motor Literate so I apologise in advance .
Cleaned out the radiator the other day, filled with new coolant and a few days later noticed coolant leaking big-time when the engine was running. I took a look underneath and it looks like it is coming from behind one of the drive wheel/belt thingies on the side of the engine. Managed to get underneath and what I think might be the water pump has a small round hole where the coolant seems to be coming out. My first thought is that it is the water pump and it is buggered. My Second thought (hope) is that perhaps there is some kind of bleeding hole with a screw missing on the waterpump. I don't have a manual (going to the library this afternoon) so I am not sure what a water pump looks like.
The curious thing is that it has just started spewing coolant, probably after the radiator flushing. Has anyone had similar problems that could offer some troubleshooting tips to me. Would a radiator sealant be a good idea?
