Found my coolant leak! is this a cracked head or just a small leak?

 

That would be a leaking freeze plug. It cost about 99c to fix.

 

How many are there on the engine? Cause i have the same leak towards the rear coming from the circle thingy

 

Not 100% but I'm pretty sure there are 5 on that side on the engine. The (circle thingy) is a freeze plug, it's designed to pop out to prevent the block from cracking under extreme temperatures. Its bet simple and cost about a dollar each to fix. Simply drain your coolant, take a punch and hammer and hit one side of the plug till it pops off or turns sideways, then remove it. Sand the edges where it seals and wipe it down really good. Buy a new plug and tap it into the hole going around the edge until it's firmly in place. Refil coolant

 

Thanks alot man. I was loosing coolant and was scared i had a cracked head. Does this have to be fixed soon or could it wait a week?

 

Those are actually called core plugs, they plug the holes where the casting sand was dumped out of the block after the casting process.

 

It can wait a while. Just make sure you have coolant and you'll be fine. And btw, if you live in the south id use a rubber expansion instead because imo they seal better. If you live in the north dont bother

 

core , freeze, welch...call it what you want.

 

just topped off on coolant today so i should be good for a bit. thanks for the help everyone

 

Np brother, best of luck

 

I add aviation form a gasket to the freeze plug before install .

 

got wrestling everyday of the week so the repairs will have to wait. just gonna keep filling the coolant for now

 

Then I shall call them Fred plugs.

 

And we'll know exactly what you're talking about!
