I found a pinhole leak in the block by the lower thermostat. it started leaking coolant yesterday, hasn't leaked any today. What should i do?

 

id wait and keep checking it periodically, it will get worse and then it will have to be fixed, so just take it easy on her.. now is it in the actual blow or where a component mates with the block cause normally a blow would crack, sounds like a a seal problem at the thermostat housing

 

more info..?

but you should fix it...

 

its in the block. i saw it shootin out like a little spray. it looks like a rock skipped up and hit it. i just need some info on a good way to seal it.

 

i'd find somebody with a welder, a tack in the spot would seal it good
