Haynes manual is telling me i need to use a sealer with the gasket. Problem is its 10pm and I have no sealer. Didn't come with the gasket and water pump. Can I just use the gasket? Will it leak?

 

When I did my water pump we covered the gasket with a thin covering of silicone but there was one point that we didnt get and and leaked. Hopes that helps

 

Dont have any silicone just gasket and pump.

 

Probably best to wait until you can dress the gasket.

 

Has to be up and running tonight. Can I use high temp red??? Found a tube of that

 

Hi temp red RTV will work fine.

 

Permatex® High-Temp Red RTV Silicone Gasket

OEM specified. Formulated for hi-temp applications, or heavy-duty use (such as towing, etc.). Replaces almost any cut gasket by making reliable “formed-in-place” gaskets that resist cracking, shrinking and migrating caused by thermal cycling. Coats pre-cut gaskets to increase reliability. Temperature range -65ºF to 650ºF (-54°C to 343°C) intermittent; resists auto and shop fluids. First generation 1970-1980 gasket maker.

Suggested Applications: Valve covers, oil pans, timing covers, water pumps, thermostat housings, transmission pans

 

I did my water pump a few months ago. No RTV on it and no leaks still

Hope it stays that way

 

Unless you have to drive is asap, it would be best to wait til you can get the stuff, until then you can get everything lined ap and squared away so it wont take more then 30 min after you start.

 

I've used spray on copper gasket on my Chevy pickup water pump. So far no leaks.
