Default Water pump gasket failure

So the gasket on my water pump failed and it drained all of my coolant while i was driving down the rd.

It sucked, luckily nothing really bad happened, but now i'm in the middle of tearing it all apart. Instead of dealing with another gasket i'm going to use a high temp silicone sealant on it - let it cure for 48 hours and put it all back together.

FYI, the gasket is a whopping ~$3.00 at the dealership. RTV is good stuff, however, I'd stick with a new gasket since they so rarely go bad and RTV is unproven in this application (I've never seen it used). You're damn lucky that you didn't overheat!

Yea, i'm not sure why but it didn't affect the operating temp at all, I didn't even know something was wrong until it stopped spitting out warm air.

I would go with the OEM gasket if I were you!

Same thing happened to my legacy and i used permatex brand "right stuff" to seal the new pump. It's been just fine for at least 10k now.

I use the OEM gasket plus RTV, on both sides of it. I did my water pump on my Legacy over 44k ago and it hasn't leaked a single drop.

Definately shouldn't leak but may be a PITA to remove some day I've found that the super nasty gasket remover goop from NAPA does the trick.

I have installed many water pumps and never had a problem with the OEM gasket.

As long as you're in there, do the works, timing belt, water pump, etc.

Not only that but it's likely the pump has failed (seized up) which may have caused excess pressure on the housing and therefore gasket leak. I've never heard of one leaking that badly, that quickly b4...
