345 heater core from engine h20 leak

The heater core in front of the passenger developed a leak. I disconnected the hoses to make a bypass as a short term fix. Then I removed the "kick" panel and the interior panel exposing the heater core. Now I can't see any way to remove the heater core from its mount. Has anyone done this before? Where is the magic screw? or whatever?

Elliot,
This one has baffled me too. I need to get in there to repair the blower fan. I've made a few attempts but could never figure out how to get in there. If anyone knows please post.

Never on a 345 but it is common to use a wire clip across the tanks, screws hold it to the sheet metal.

I bypassed mine as well. With warmer weather coming, maybe you would want to leave it that way until Fall.
I experienced no problems with mine off all last year, but then again we use little or no heat here in Georgia while driving.

The carpeted "kick-board" in front of the passenger's feet just pulled out on ours. Pull on the side towards the center of the moho. Had to disconnect one of the doghouse latches to get it out of the way. Then about a dozen sheet metal screws around the metal cover over brought that off. The blower motor is held to the top by a couple of nuts. Hex, not 2-legged. There is a clamp around the blower motor that only had one bolt holding it, but taking that off while the blower was still in doesn't give it enough room to get the motor out.
Hope this helps to get at the blower. I still haven't removed the heater core yet. That's being held up while I fix the propane water heater - that's first priority.

Elliot,
Thanks for sharing on this one. The heater box is one of the mysteries most of us have not figured out yet.

I have my core out, if I remember correctly it just slides out after the hoses are disconnected. Also, I looked at the core and couldn't find any screw or bolt holes to secure the core to the housing. Good Luck, Rob
