Heater core play in tube

[juancache]

I bought a Murray heater core from O'Reilly. There is some play in one of the lines that runs to the core. I'm a little bit concerned about this. Should I be concerned? I can't upload a video. Posting a link to a video showing the movement.

That didn't seem like a lot of movement, but I'm not the one feeling it. It looks like it's a shark bite connection and not soldered. Those always feel sloppy to me. Maybe try a leak test with a garden hose. Fill it up with water, cap off one side, Gently add pressure until the hose is firm and see if it holds remembering city water pressure is typically 45-80 psi and radiator caps typically vent at 16 psi.

If you want to be super a*n*a*l about it you can rinse it out with distilled water when you are done.

No that's normal they're supposed to move a little bit

Thanks.

Mine had more play than that, after I put it in the housing and put the clamp back on, I tapped the crimped area lightly with a punch and hammer to snug it up. Don't know if it did anything to help at all though

I wouldn't touch it with anything, fill both ends with distilled water and see if it leaks.

I think both the evap & heater pipes are made to swivel
so that you have some play to work them through the firewall
