Expansion plug seeping

Recommended Posts

I see I'm going to have to replace an expansion plug in my CTD. I have a some leakage coming from one of my plugs and don't wan't to revisit the problem again when I install a new one. What type of Permatex or sealer is best for this repair?

Ive never had to use any kind of sealant on freeze plugs... The reason the freeze plug are failing is because the coolant turned Acidic or Basic from lack of coolant flushes... Just because it green. orange, yellow or what every color doesn't mean its still good...

Thanks for your reply. I replaced the plug once last year and put a non harding sealer around the edge. It still had some seepage then. I'll install it this time without sealer like you suggested.What did you use to install your plug? I made a jig to pound the plug into block without going to far. My first try I knocked the plug into the water jacket and had to use a magnet to retrieve it.

Ok...(My Bad) I thought this was a first time run. :doh: So there is something wrong if you replace it once and it coming back with another leak... So at this point I would inspect the hole for damage. Clean it really good and look closely. Like in my mind to get it to seal I would wipe a coat of silicone in the hole. As for installing normally go for flush then quit... Which plug is this?
