Hi Everyone,
In this video I'm finishing the repair the heater system by adding missing pipework, and I'm also having fun fixing a blown engine block core plug.

james if the new freeze plugs aren't leaking then job accomplished.... but i wanted to mention that up here in canada where it gets very very very cold..... freeze plugs are installed cup side down. in other words the hollow side of the freeze plug is on the outside. if they don't leak don;t bother. but if they do.... you might want to try this way. cheers,

Do you use over sized plugs for that (i.e. how do they form a seal)? I don't really have to worry about cold temperatures here so I can get away without some of the steps others need.

@nickyalousakis3851 2 года назад

core plugs seal by shrinking into the block hole. the bottom of the cup edge is slightly smaller than the top side of the cup. when pumched into the hole the plug shrinks into the hole.... naturally the walls of both sides need to be scuff free. so sealant on old engines is a good idea..... if she doesn;t leak don't worry.

@@jamesfromwellington oh yes we call them freeze plugs up here.... but they don't do anything to prevent cracked engine blocks. i think they are more to close up holes needed in the casting process or holes for maintenance to clear out scale.
