I've been trying to resolve overheating issues that began after hitting a sandbar. I started with the water pump since it was due for it, but am still getting overheat alarm and the telltale looks light for a new pump. Went to check/clean the strainer and it sheared right off. Too bad they used plastic for this part! I used the 18 mm deep well socket so not sure where I screwed up. Obviously I need a new strainer.What I'm looking for is advice on how to get the old one out. It's flush..nothing to grab or turn. Do I need to drill it out? If so how and is this a job for a DIY? Changing water pumps is where I max out as far mechanical ability...
