Want this question answered?
when replacing a frost plug u can use a sealant but only use silicone u dont realy need it and yes u have to clean the area good
If it is already frozen why do you want to freeze it?
no, use rtv sealant
I my self would not, That's what gaskets are for. unless there is some inperfections were the gaskets go,if there is use a small amount of sealant only. and be sure its OEM sealer. And install gaskets.
use a screwdriver to pop the old freeze plug out. Be careful not to score the surrounding metal. Fit the new plug into place then tap gently around it to seat the plug.
Rust and corrosion are hard on freeze plugs. In a temperate climate one might be tempted to not use anti-freeze coolant in the engine, but that's a mistake, since the water just speeds up the rust. With the salt air and humidity always working on anything that rusts, a freeze plug will easily rust through. Cost of repairing the freeze plug will vary greatly, depending on what needs to be removed to get to it. If the freeze plug is RIGHT THERE, with nothing in the way, it might cost you $20.00. If it's behind the starter, a motor mount, the air conditioner compressor or something else that's likely to be difficult to remove, replacing the freeze plug could cost a couple hundred dollars. The freeze plug itself is cheap. A couple dollars at most. But getting to it can be anywhere from simple to a major operation.
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.
When a freeze plug is damaged, coolant can leak from the vehicle. Using a screwdriver, roll the lip of the plug over toward the middle, being careful not to scratch the sidewall. Grab the lip with a pair of pliers and twist the plug out. Use a hammer to tap in the new plug.
You have to remove the engine and get freeze plugs pressed in. If you use a rubber plug which have a brass face and bolt in. Remember that they are a temporary fix and will come out if your engine over pressureizes.
No sealant is used in that application.
none. if you use a gasket dont use sealant. Also never use sealant on a automatic trannsmission. It could damage the tranny and will not last.
The best option for a fix is to use a sealant. If you don't want to use a sealant then you're going to have to replace it all. I really recommend to use the sealant.
