I have a 3.0GL Volvo Penta and I am replacing the old parts after an overheating issue this last weekend. Thinking I could just pop out the old one and then pop in the new one but wow. I had to pretty much hammer out the old one as it was stuck in it and now trying to put the new one in and can not figure out how to fit it in there. Does anyone have any advice? I can not get this thing to fit in the middle of the housing no matter what I do. Please help
