Frozen coolant? How worried should i be now!!!

MOVE AWAY!!!!!! WHY its the North Pole....

JJ man that sucks. BURRRRR

If you have a block heater plug that sucker in!!! For those of you that think "freeze Plugs" pop out to save the block, you are mistaken. Freeze plugs are there from the casting process in order to remove excess sand. There is no coolant in the freeze plug area.

how much good will the block heater do? i didnt know it would get so cold, so it wasn't plugged in, but now it is. how far will the heat spread? it's also supposed to get like 7* colder tonight than it was last night....

Plug it in, It will help.

Straight antifreeze will get slushy but not freeze solid.

Whoever told you that was only partially correct.

There is coolant in the block. The freeze plugs will pop out if there is coolant in there that freezes. Freeze plugs can leak coolant also if not fitted properly.



Freeze plug is a misnomer for Core plug or expansion plug, but is commonly refered by many a mechanic as a 'frost plug'




A true Freeze Plug is an expansion plug located in the side of an engine block that is supposed to protect the block against freeze damage. Water expands when it turns to ice, and if the coolant doesn't have enough antifreeze protection it can freeze and crack the engine block. The freeze plugs (there are usually several) are supposed to pop out under such conditions to relieve the pressure on the block.

Most of the plugs to be found on an engine are actually to plug the holes where sand cores have been held. The sand cores are used in the casting process to form internal cavities in the engine block or cylinder head, for cooling water for example, and so should really be referred to as core plugs.

Freeze/core plugs can often be a source of troublesome leaks as a result of internal cooling system corrosion. Ease of replacement depends on accessibility. In many cases the plug area will be difficult to reach and using a mallet to perform maintenance or replacement will be nearly impossible without special facilities. Expanding rubber plugs are available as replacements when access is a problem.

A variety of block heater called a "freeze plug heater" can be installed, replacing the freeze plugs, to warm the engine before start up

-40???? **** that i cant stand when its 10* out!

The only concern I would have if I were you is you might need to get the vehicle warm without starting it somehow. When I did this my water pump didnt like me and broke due to the cold/icy mix.

I blew a freeze plug out in my old car.....guess what poured out in a matter of seconds causing my low coolant light and my temp light to come on...You guessed it

More coolant to less water should fix this as long as adding the extra coolant wont hurt the engine... This should lower the freezing point depression and the boiling point elevation and cure your problem... Just a little chemistry thrown in there...
