Cooling Problem w/ 4.3 GL vovlo I/O

I am going to purchase a couple of plugs and install them to see if there are any other pending (hidden) issues. I had been told that I could get expansion plugs from a local parts dealer that are expandable by way of a bolt instead of the "tap in" types that would be supplied by Volvo (or aftermarket). Has anyone used these types of plugs? Can anyone recommend how to replace the plug that is behind the motor mount? It would be much easier to take it to a local repair shop but I want to do the work myself.... how else am I to learn the fundamentals? The rubber expansion plugs will work, to a point. In a marine environment, I would only use them to diagnose any further issues on a test basis, which I have done, because they have a probability of popping out, which will very quickly fill the bilge to a dangerous level with very little advance notice. No typical bilge pump would be able to keep up. If you can somehow extract the obstructed view/access one, you can probably slip a temporary plug in blind, tighten & test, otherwise you are looking at pulling the engine twice if you go rubber, once if you go with the brass to start & luck out with no other issues at re-start. Which brings us back to the initial failure - did you get ALL rubber fragments/parts out of the engine & drive when changing the impeller? If you can account for all parts, do the brass plugs and hope that the block is not cracked. Did you have any kind of low temperature alert or alarm in your storage area? Rob |
