Hey guys,
changing the water pump on my 1.4i kfw it says in the instructions that came with the pump to use sealant but wasn't sure weather that info is correct?

It can't hurt to put a thin smear on can it.

I had exactly the same question late last year, I called the pump manufacturers (INA) & was told that if I had an unused steel crush gasket that came with the pump, then no sealant was needed, but if no gasket then a small amount is fine. I had the gasket, but used a small smear as well as the gasket to be sure & all is fine.
The argument against sealant is that by using too much, some can come loose in the water flow & get caught around the impeller.
An o-ring is probably fine on it's own, but again a small smear of sealant probably won't hurt IMHO
