I went through a freeze plug job. The rubber freeze plug will get you home, buy you time. Pulled the engine and to my surprise freeze plugs were in horrendous shape. The cooling jackets were full of “mud”. 99 model with 62,000 miles but the cooling was neglected. Removed old plugs, flushed the engine and installed brass plugs with some RTV and it works perfectly.
Hi! Great video! Going to install same plug on the back of the head on my AMC 360, Javelin. Pain in the ass to get out the old plug, its so close to the firewall. But install this rubber plug is don in 5 min. Important as you say thread locker, and a good clean up around the plug hole and dry. Then I will think it will last for years
hi i have a Saab 900i 1993 model non-turbo the 2 welch plugs are weeping behind the manifold would the ones you have suit or am i better off putting brass ones back in
I have two installed in an old 1974 that I've owned for about 3 years. 2 years ago, on very cold days when I don't use the car for many days there is a very slight seep that develops. Not sure how old the plugs are but the engine itself is at around 300k. I tighten the nut on the plugs and that slows the leak down because those nuts do loosens up. I'm thinking about adding thread locker as a last ditch effort before having to remove the exhaust manifold and redoing both of these plugs. An upside to having these rubber ones is that at least I wont have to deal with removing rusty seized plugs that come apart in the engine during removal. I'm curious, will the plug pop out on its own if I unscrew the nut all the way?
Threadlocker will help! I would not take the nut completely out because the bolt, along with the back washer has a chance of going inside the coolant passage depending on how big the passage is.
They are mostly universal. So find just a regular freeze plug for your car and check the diameter on it on the website (I use O'Reilly's) and then find a rubber freeze plug that fits within the specs. Hope this helps
Seems to me that this type of plug would defeat the entire purpose of the freeze plug concept,,aren't freeze plugs designed to pop out incase of freezing ,,,therefor cracking your block ?
While the freeze plugs are designed to do just that, the hole they are plugging is actually a result of the casting process, which would need to be plugged anyways. These wont save your block in a hard freeze, but they will easily plug the giant hole in it.
No,do not assume that they will pop out.they are there to remove the sand form from the casting process.firstly,have the correct ratio of Coolant so as not to have ice form in the block.
Helicoil it bro they dont really work on oil that much especially on an atv that's flying around off road. Lots of kits available to drill out and tap and put in a thread saver and then get a new drain plug
Do they last? I recently installed them on my 87 Ltd crown Victoria and had people say they last years while others say months any help will be appreciated
It's all about the way you install it. If you used thread locker and had it seat right and tightened it tight they should not fail. Usually the cause of fail is installer error in my experience. Hope this helps!
@@saabin907-5 update I've had it in my car for 1 year now and never leaked nor have I needed to tighten them but I'm changing my motor mounts soon so I'm gonna put locking nuts on them just to be safe
I looked up the metal freeze plug size my truck took. Then I went to the store and found the same diameter rubber freeze plug. I do not recall. But doing that should ensure the right rubber freeze plug
Sold the truck. Drove it hard for awhile. Know a few people that have them and they check on them everytime they change the oil. Seem okay! Hope this helps
If installed incorrectly yes. They can pop out. That is due to not being tight enough or loosening or not being pushed in far enough. Follow my video and should last a long time. Been over a year and still no leaks. However I always keep an extra one in my glovebox just in case. Hope this helps,!
@@sm7501 yes. Whenever I do them I keep a spare on hand. Small enough to fit in the glovebox and all. Then when you use the spare take the other back for warranty unless you can't find it
