Want this question answered?
There are 8 freeze plugs. If you have a bad one it's where the coolant is leaking from the engine block or a cylinder head, .
The engine will leak out coolant/antifreeze from the freeze plug area. Freeze plugs can be replaced, it may take a lot of work to replace one but they are made to be replaceable. It is not advisable to drive any vehicle with a blown freeze plug.
I asked the question myself with no feedback. So I'm fixin to find out. By looking at it...it appears to be that of a freeze plug, I have just not seen one there in that paticular spot before, but then I've never owned that yr. olds before. So taking an educated guess in lack of any knowledgeable answers i'd say yes
There isn't just ONE freeze plug; there are many, and they're all in the "water jacket" surrounding the cylinders.
No ( not unless you want to wreck the engine ) If the freeze plug is " blown " than the engine coolant will just pour out
There are about 8 freeze plugs which one is leaking?
take a punch or chisel and pop the old one out the take a socket the size of the freeze plug and hammer it in
The hardest part of the job is GETTING TO the freeze plug. Depending on which one is leaking, sometimes you need to pull quite a bit of stuff just to get to the freeze plug. You need to be able to examine it and have clear access to the freeze plug and if it's one of the rear plugs (under the flywheel), you're only option is to pull the engine and/or transmission. Once you can get to it, just drive a screwdriver or other sharp object through the freeze plug and pry it out. Clean the block around the freeze plug then install one of the aftermarket types, preferably one that allows you to tighten a bolt to install it. You'll have trouble getting an original type freeze plug to seal if you don't have the engine block sitting on a workbench. Any time you have an engine machined, always replace the freeze plugs.
It depends on the freeze plug. Generally though, pull everything out of the way so that you can get to it. There may be one or more in the BACK of the engine, so to get to those you will need to separate the engine and transmission.If it's a side freeze plug, for example behind the starter, you would need to pull the starter and anything else that might hinder access to the freeze plug. Then, pull the freeze plug out using whatever method you find acceptable. Generally, if the freeze plug is rusted, you can put a large screwdriver or small pry bar into the weakened area then pry out the freeze plug.Once the old plug has been removed, clean the opening and install the new one. If you have the type with the tightening screw, just tighten it in to seal it. Otherwise you'll need to press in the new one, making sure to get a good seal.
First check and see if there is a pouch located directly beside your battery. If there is a pouch it will contain a plug that is for the factory engine block heater. If there is no plug then you can pursue an aftermarket type. There are several types. If you want to use a freeze plug block heater, you'll need to have someone help you remove a freeze plug. That usually requires that you remove a lot of the peripheral equipment until you can get a clear access to one of the freeze plugs. Measure the freeze plug then go to an auto parts store and purchase a freeze plug block heater of that specific size. Once you have one that will fit into the hole, you can drill a hole in the freeze plug, then use a prying instrument to remove the old freeze plug. The block heater freeze plug usually goes in with a nut to tighten the freeze plug into the hole. BTW, you'll get a lot of antifreeze all over when you do this, and plan on taking your time since it will be time consuming.
There is not one freeze plug. There many freeze plugs, ususally there are three on each side of the engine block, one in the rear inside the bellhousing, and there is usually one at each end of both cylinder heads. There may be more depending on the engine.
Yes there are freeze plug(S) on a ford 390. There is more then one on each side though I don't recall how many, I believe there are 6.
