Sounds like a freeze plug, or soft plug, or frost plug, etc.... everybody has a different name for them. Should be able to get them at just about any parts store, usually quite cheap.

I've never changed one, but it seems to me that they just tap in

heres a post at supramania talking about the types to buy
http://www.supramania.com/forums/sho...ep-blowing-out

and some installation tips.
Its funny that those blew out.. I could quote you some history of the freeze plugs but the short of it is that there made in the factory and normally don't need replacing unless someone replaced them before. nominal word being NORMALLY. Good luck

Wow someone with the same problem i had. I found then at an auto zone and they were pretty cheap. You have to remove the intake to give yourself room to get them out. They were a little tricky to get out. What i did was get a small punch and tap the freeze out plug on the right side to get it sideways. After,I used a vise grip to get it out. Make sure you check out the other plugs. I believe there are 3 freeze out plugs on each side of the motor.

When I replaced mine, I used the rubber plugs with a metal plate on each side and a bolt in th middle. I cut a small notch on the outside plate to use a screw driver so i can hold the plug while i tightened the bolt. It's been about 6 months since the repair and no more leak.

I replaced the first 2 plugs on the intake side (both had pin holes, like someone installed them with a punch) and the center plug on the exhaust(blew out). I was going through alot of cooling system issues at the time (bad t-stat, leaking radiator, throttle body hoses leaking,coolant hose under t-stat and freeze out plugs)... Maybe it was just me but check all you cooling system components.

Smile checking your thermostat

Hi!
I've been reading these pages recently and a lot has been said about bad thermostats. If you think you have a bad one -- try this : put a known good one and the suspect one in an OLD metal container of water ( enough to cover the thermostats ) and heat the water up -- it should be closed . then as the water starts to boil ,it should open up fully at the same time as the good one , and close when dipped in cold water.
Doing this first -BEFORE you fit the new one will prove the thermostat and give you an idea of it's opening temperature , opening before the water has boiled - engine may be running cool / late or not opening fully -possibility of overheating.
If you have an infra-red thermometer you can measure the temperature more accurately during the test.
Failed thermostats should fail safe --remain open when cold.
