wp bolts don't go to coolant jacket??

So i keep reading that 4 bolts go into the water pump jacket, but when I had removed those 4 bolts, I saw no evidence of water, and when I stuck a paper clip in each of the holes, it bottoms out.
So I installed it without thread sealer. Now I had to pull it again, but I ran it for a a good period of time before and it never seeped out the bolts. I just want to make triple sure before I add coolant.

 

coolant can seep into the holes of the timing over from the water pump. i usually put anti seize on the shank section of the bolts and thread sealer on threaded portion. i dont remember if the bolt holes are blind or not but have had plenty of these bolts seized in the cover and even brake that i wont even chance the bolt seizing into the cover.

 

ok I'll just do that to all the bolts?

 

Use the common Teflon thread sealer paste on the four long bolts, antiseize on the others.

 

I went ahead and sealed&antiseized up all bolts thanks guys.

 

That's good advice to anti-sieze the shanks on the wp bolts that go through the cover.
