DIY Auto Repairs Saved Me Thousands! - Part 2

Thankfully, I read online about engine block/ head sealers such as K-Seal and Blue Devil. These are products that you can add directly into the coolant system, that circulate through the cooling system and seal up any cracks or leaks that have formed, so long as they are not too severe. While they don't always work, many people online had attested that using one of these products had saved them thousands of dollars.

I figured it was worth a try! Searching the shelves of the nearest Auto Zone, I found that besides K-Seal and Blue Devil, there are a bunch of other similar products available. I tried to pick the brains of the workers there to see if anyone had used any of them before, or if they had a recommendation. No-one really had, but one told me that Blue Devil will give you your money back if it doesn't fix the problem.

I also saw that K-Seal had a variety of different products with slightly different names -Ultimate, Heavy Duty, Pour and Go, etc - but they all seemed to do about the same thing, as far as I could tell. Their website has no information about the differences in the various product types, and I couldn't find that information anywhere else online. I ultimately went with the K-Seal Multi-Purpose One-Step Permanent Coolant Leak Repair , since it was the cheapest of all the products and I had already blown 60 bucks on the useless mechanic. It was less than $10.
