I have searched here and on other forums but haven't found the answer to this question yet: can the heater inlet tube on the driver side of the water pump being somewhat wobbly and still be fine?
I just got done doing a bunch of work, replacing the water pump being some of that work, and this inlet tube came with the water pump and a small o ring to fit on the end. The instructions with the water pump say to just push it on the tube, then push the tube into the pump. That's it. Doesn't mention to rtv it or anything. I did put a very tiny amount which I know didn't seal anything, and when I got it all back together, I started pouring coolant in the radiator to fill it. It started coming out of the water pump where the inlet tube sits in it pretty heavily. So I drained it and cleaned it and dried it off, then I pulled the tube out, replaced the o ring, and then put a ton of red rtv high heat around the tube and then shoved it back in.a little bit of it oozed up out of the hole so I'm assuming it's spread all the way around it. Then I put some more rtv around the base of it as extra insurance so now I have a good amount. I figured I would wait until tomorrow for it to fully cure and start the process over again. I just checked it now after 4 hours of it set, and its dries and not sticky, but that tube wobbles a little bit. I don't want to yank on it too much but I'm wondering if this will be fine. The old water pump didn't have any play in the tube and it was seized up in it. Not sure if it's corrosion or they jb welded it or what. What's the verdict on this? I think this was a horrible design and could have been better.
