Mine was worse on the hottest days. Then I changed the rad cap and seals.

There's a kit, with seals and shaft o-ring, buy it now. It's not expensive.

The best procedure is to take the whole case off rather than just the water pump housing. This lets you push the seals in with less risk of damaging the lip. There's a post on here somewhere that gives the details.
