I am attempting my first DIY water pump + timing belt installation. I already have everything apart. The vehicle is a 2000 KIA SPORTAGE EX.
The water pump that came with a paper gasket and the instruction sheet that came with it is a bit vague on regards with sealants and the KIA repair manual doesn’t mention anything about it.
Some say to use a sealant on both sides of a paper gasket when installing a water pump. Some people say to use only on the pump side. Some say to not use any at all. Which is it?
Also if you indeed need a sealant… what sealant should I use?
On the thermostat housing and the water pump that was already in the car, it was coated with some black rubber material. I assume this is silicone. This rubber material actually fell apart and it was just hanging inside the housing which doesn’t look like a good thing at all. This is the reason why I wanted to find out if I have to use sealants when using paper gaskets. Hope you guys can help me out.
