Impeller quick question on grease

[Dino89]

After watching YouTube it was common to use grease on assembly ,so when assembling the impeller I put a smear of quicksilver 2-4-c grease on the rubber to ease it into housing
Just read that some grease can break down rubber , is this the case ? Should I strip and clean it off or is this grease fine ? Thanx

Factory manual for impeller replacement on mine says to "Apply a light coat of Quicksilver 2-4-C Multi-Lube on inside of water pump insert".
That's the bit inside the water pump cover that the tips of the impeller rub against.
So you're safe

Just for info...my impellers come with a sachet of glycerine.

Impeller is probably a synthetic rubber which would not be affected by petroleum base products.

I thought that was for the posh w&%k to celebrate getting the impeller fitted.

Apologies for lowering the tone.

Silicone grease also works for the impeller side of things.

Be very sparing if using silicone grease, just a smear. I managed to severely restrict a waterway by being over generous with it. I was using it because of the warning re spirit based grease harming rubber impellers.
In hindsight the petroleum grease would have been less problematic.

Katica should set the right tone for you...
