What happens when you put sealant in an engine?
What happens is this: These sealants are in liquid form within the coolant and harmless. However, as soon as it encounters air – usually at a leak – it solidifies and seals the leak. What it’s supposed to do. The problem is that in old, unsealed engine cooling systems there is often air trapped inside and so the sealant solidifies in the engine. Usually the first thing to get clogged is the heater matrix which has quite narrow channels, then the cooling radiator and then the engine cooling galleries. This latter is very dangerous because the solidified clumps of sealant prevent various nooks and crannies inside the engine from being cooled by the coolant, so they overheat and distort.
Can sealant fix a leak?
With a serious leak, no amount of sealant is going to fix it, so we’re only talking about minor, persistent leaks – and there is only one right way of dealing with it. Replace the offending part.
