That's the thing, for all the warnings I can honestly say I've never seen a rad sealer "gum things up" when used in the suggested dose.

Not saying you will get problems but why risk it for a simple exterior fix?

Seen plenty of alloy heads come off like that just because if weak / old coolant allowing corrosion to happen. If that was caused by sealer they must have been using it almost neat!

I did read their post? And my quote is correct. Why mess around trying to fix it and spend as much as a replacement costs when they could get one much sooner.

No need to wait a week, use the extra money saved on not having to botch it on getting the new tank.

How do you know the week isnt the time for the part to arrive?
