Core plugs

[johnnywgk]

Hi all, I'll ask here so I know I'll get a serious answer.

About september last year I found a core plug (I think)under my car. not sure if it's off my car or one of my Dads (or from Mars).

Question is, why would one fall out?

I've not been near my car for ages, so hav'nt checked it, so thought I'd ask first.

If it is off my car, how do you refit them?

Many thanks.

If it is off your car - didn't it create a big puddle???

Cold night, no anti-freeze, coolant freezes and pops core plug out. Can get a bit nippy by September but not usually sub zero

As Garry said, was it lying in a pool of coolant when you picked it up?

I wouldn't worry about re-fitting till you're sure its from your engine, they can be very difficult to replace with limited access (engine out jobbie?).

If its just fallen out , you will have last all or most of your cooling system water.
Either rusted out or frozen water has pushed it out!
Dont start until you check water levels! ( suck eggs sorry)

Did'nt notice a puddle, I only see my car every month or so.

When the weather gets better I'll top it up with water/antifreeze, and see if it leaks.

Not a freezing problem as it was fairly mild when I fount it, just did'nt have time to check.

Ouch! if it is engine out.

Will look when the weather gets a bit sunnier/

Looking on the bright side someone may have stashed a spare core plug somewhere under the bonnet and it has just. Fallen from its perch!

What size (diameter) is it roughly?
Not forced to be from the block.
