|||Use RTV in fact for some installations Toyota recommends it, just don%26#039;t go overboard. I usually apply a bead about 2mm thick or you can carefully smear it around with your fingers. If you use too much it will extrude into places where you don%26#039;t want it to, the pieces can break off and cause all sorts of mischief.|||use barely any sealant ..just enough too evenly make the gasket sticky on both sides|||you are not supposed to use rtv on a water pump however every one that I have done i put a TINY amount on the gasket just to make is stick to the pump to make it easier but do not use it as a gasket and do not let it overlap into the pump. Basically if you can do it without then great but if you cant seem to gegt the gasket to stay put then a little wont hurt.|||NO RTV or Permatex! RTV will melt into the cooling system and cause more problems! Permatex :-D Only if you %26quot;Never%26quot; want to get the water pump off again. When Permatex dries with heat it all but welds things together. I use a little Anti-seize or light coating of grease to the gasket soft so it can be taken off easy the next time.|||NO,...Indian head (thats the brand name) or a spray.
