Changed my water pump. Help me about silicone sealant?!
I changed my waterpump and i didn’t have a gasket so i had to use permatex ultra black silicone as a gasket. I let it sit for 15 mins and then bolted it on very tight.
When is it dried enough so i can fill er up with coolant?
It’s probably too wet to run yet.

i think i squeezed out most of the stuff when tightening it on.. I guess it still fills in the microscopic gaps so it shouldn’t leak.. right?
from what I found by quickly googling if :
For best results, clean and dry all surfaces with a residue-free solvent, such as Permatex® Brake & Parts Cleaner.
Cut nozzle to desired bead size gaskets are best formed using a 1/16” to 1/4” bead.
Apply a continuous and even bead of silicone to one surface, surrounding all bolt holes. Remove excess with knife at once. Assemble parts immediately. Do not squeeze out silicone by over tightening bolts. Re-torque will not be necessary.
Silicone dries in 1 hour, and fully cures in 24 hours, at 70˚F - 50% relative humidity. Allow more time in cold weather.
Replace cap after use. Clean hands with dry cloth or Permatex® Fast Orange® Hand Cleaner. Clean tools with non-flammable cleaning fluid.
NOTE: Not recommended for use on head gaskets or parts in contact with gasoline.
I think if I were you I would redo it . If you feel brave you can always wait 24h for the thing to cure then try to feel it and see if it leak . If it doesn’t check you coolant level for the next few hundred miles . (Do not do this if you don’t feel confident about it or can’t afford to mess up your car, as I said if it was my car I would probably remove the pump and reapply the sealant .)
Id wait for 24hours to allow it to dry
Did you just use silicon like the bathroom sealant well I think it’ll be fine
This is oil pan gasket silicone.
24 hours with most silicone based sealants, but you can fill up after an hour or so
