Hello,

my waterpump is leaking water. I found an affordable service kit. The pump is not driven by the belt but directly from the engine housing. Can I just screw it of or is the whole engine full of oil and I have to take of the engine oil?

Thank you for your feedback!

I had to replace the impeller a few years ago. Just take the belt shroud off the front and then unscrew the plate on the front of the water pump. Seem to remember it was all pretty simple and went smoothly.
