Hi everyone,

We’re trying to research replacing our heater core in our 2001 National Dolphin. My husband is quite mechanical & would like to do it himself. I read on line about using a dremmel tool to cut the plastic shroud rather than removing the dash. This was not for a Dolphin, so am looking for anyones experience with a Dolphin V10 on a F53 chassis. Is the heater core accessible without removing the dash, or is removing it not a big deal? We also hope to avoid recharging our AC.

I have searched this forum and have not been able to find any similar threads.

Thanks in advance! Any input is greatly appreciated!

I did this on a P-30 chassis Safari Trek where the heater housing was on the outside of the firewall and easily accessible.

Can you see the heater core housing & hoses on your National?. If so, and assuming the housing is plastic, cutting a large hole should be easier than removing the entire housing. I used the flat cutting blade on an electric soldering iron then taped the cut piece back in place. Much easier, no dust from a dremel cutting wheel, and no disturbing any A/C components.
