Mounting Bracket for Expansion Tank Install

I couldn't find anything in the search.

I am replacing my radiator. I did the rest of the cooling system less than 10k ago. I have the old radiator out, and took the mounting bracket for the expansion tank off it. I am trying to install it onto the new Behr radiator.

There are two screws, and the male "nub" with o-ring that plugs into the female on the radiator. I replaced the o-ring. Is it supposed to pop in or do the screws just hold it tight? I've tried to press it in but it doesn't lock in.

If my description doesn't make sense I'll upload pictures. I just want to make sure that I don't have leaks!

Just curious. What happened to the old radiator? And looking back now, would you have replaced it during the coolant refresh 10k ago?

SekouDATduD3, thanks. I ended up just screwing it and installed it earlier today and so far I'm not seeing any leaks. It really seemed as if it should pop into place, but apparently not.

Mango, I had a slow leak which I think was coming from the bottom of the radiator where the plastic meets metal on the drivers side. Looking back, yes I would have replaced it.

I understand the cooling system, but I do think 60k is a little early to replace everything. I'm sure that people have had instances, but generally I feel like most of the parts should last 80-90k at a minimum, but that's just my opinion!

It's just a hunch, but because of the design of the float gauge in the expansion tank, I believe that a lot of people are overfilling their systems causing them to fail prematurely.

I agree 80-90k is fine. I just say 60-75 as an extra preventive measure. The expansion tanks, in my experience, do not like the 90,000 mile mark at all. So by pushing it to 90, you're really pushing it, IMO.

I got 115,000 out of my expansion tank before it failed. So there! Nyah!
