Re: radiator hose sealant
If you are using the original type hose clamps a leak is often caused by the little tab that is supposed to glide across the outer diameter of the hose. Instead it digs into the hose and creates a tunnel right below it. The more you tighten the clamp the larger the tunnel gets.
What I do is use a product called Silicone spray lubricant by Gunk. I spray both the inside and out side of the hose with it. The spray on the inside makes it slide onto the castings easy and the spray on the outside lets the little tab glide across the hose without digging in.
I use original clamps and without any sealer and do not have a problem with hose leaks.
