TTDRIVER Posted March 26, 2004 Share #1 Posted March 26, 2004 Hey guys I was taking a look at my engine today, and noticed that the circular caps pluged on the oil filter side of the block. One of them seems to have a hole in it. More like a broken hole the size of this:cry: . What should I do? Can I replace it or should I not worry. If so how do I get a new one and whats the process of removal. Thanks Link to comment Share on other sites More sharing options...
Gee Posted March 26, 2004 Share #2 Posted March 26, 2004 Are you talking about the welch plugs /freeze plugs? If there is a hole in one of them the block will leak coolant, unless the block is all silted up inside. You need to pull it out and tap in a new one (with a bit of gasket cement around the edges to make it secure).You should be able to get some from any auto store.Don't tap too hard or it'll go into the water gallery!

When installing new one, you use a large socket or piece of pipe that just barely fits into the depression of the new plug and CAREFULLY tap it evenly into the block until the lip is just flush with the outer surface of the block. BTW, if one is bad, examne ALL of them to verify condition. They have all been installed the same length of time, and have been subjected to the same corrosive environment. They are on BOTH SIDES OF THE BLOCK.As for the "piece" missing from the old plug.................drain and flush the coolant system thoroughly.

Bambikiller240 Posted March 26, 2004 Share #6 Posted March 26, 2004 Originally posted by TTDRIVER Thanks! So local parst stores will have the caps? I would think so. If not, your local Nissan dealer should. (or MSA)You want to ask for Freeze plugs, or Welch plugs. same thing Link to comment Share on other sites More sharing options...

Bambikiller240 Posted March 26, 2004 Share #8 Posted March 26, 2004 Oh $hit! If you can't find them locally, I think I have a set left over from my engine project that I could sell cheap. Let me know if you need them. Might take a few days to locate in my storage. Link to comment Share on other sites More sharing options...
