Should I Put Sealant On Water Pump Gasket

• #1

I'1000 going to fit a new raw water pump shortly. Should the gasket take sealant on or not? If so, what practise y'all recommend? In that location is no manual that I know of to consult.

I'one thousand going to fit a new raw water pump soon. Should the gasket accept sealant on or not? If so, what practice you lot recommend? At that place is no manual that I know of to consult.

If in doubtfulness, I would utilise Hylomar Blue which is a sparse non setting jointing compound. Smear thin layer on the gasket face and bolt up.

If the joint faces are in good status sealant should not be necessary and I would just ensure that both sides of the gasket are well rubbed with engine grease before refitting.

If the joint faces are non good I would probably use an RTV silicone gasket sealant. This will seal perfectly on poor surfaces fifty-fifty without the proper gasket and is like shooting fish in a barrel to remove if you always need to access the pump again. However, Hylomar Bluish will also do the pull a fast one on in these circumstances.

I learnt a valuable lesson at the roadside with a petrol 2.25 Landy 90 that had just died on me. RAC man took carb autonomously to discover some muppet had rebuilt the carb with orange sealant every bit well as gaskets. When the carb was reassembled, excess sealant patently squeezes out on the within, and is available to block jets... Whilst a h2o pump is less disquisitional than carb jets, I wouldn't want gobs of sealant trying to sneak through my heat exchanger...

Plus 1 for Hylomar Blue - thin smear.
Less is more than....

The original product was developed in conjunction with Rolls-Royce and was used for sealing aircraft engines. Hylomar continues to manufacture Rolls-Royce approved products for sealing aeronautical turbines.

Engine, compressor, electric motor, heavy industrial equipment, gearbox, defence manufacture component, turbine and many other original equipment manufacturers choose Hylomar non-setting compounds for their sealing and bonding applications.

Good plenty for me!

RTV /silicones are the work of the devil and a sure sign of apprentice intervention.
They cause as many problems as they fix in these applications.

Oh love. That means that three of the production cars I take worked on this year must have been designed and congenital by amateurs as in 4 different archetype gasket locations there is no gasket fitted at the factory. They use RTV Silicone and when you remove and refit the component you take to use RTV. There is no culling. :encouragement:

Perhaps things are built differently downwardly under?

Do what it says in the manual for your engine. I've never used anything apart from a flake of grease into hold it in place.

My (Nanni engine) manual is ane of few words ... none of them about this. I've got enough to become on now thank you.

Ensure both faces are clean and gratuitous of former gasket.
