I just finished a heater core replacement on my 1997 Grand Cherokee using the cheat method in the video. It is a time saver, does NOT compromise anything and easy to do. Instead of using JB weld or whatever is used in this video, I used a black commercial grade weather strip adhesive made by 3M that will bond the part that was cut out and looks almost invisible to the eye. This stuff is sticky and cures solid.

Just wrapped this job up on my leaky heater core. This saved me so many hours, to seal up the cuts i just used ole mexican chrome tape :) Great write up man! TY

Thanks Dan... I'm not a mechanic by any means but I do try to repair anything that I can do myself. You saved me so much work and alot of complaints from my neighbors for alot of cussing..lol thanks again.

Great video , to the point, you made aware of what to look out for, I will be taking on the exact same job, great video

Planning a heater core replacement on my 98 ZJ and going to try this route will update - thanks for the post Dan

my video editing program sucks, sorry for the delayed audio and glitches

Thanks for posting this. I have been putting this job off because of the A/C issue so looks Iike this is worth a try. I think you did a good job with the video. And I hope you just ignore the morons that can't seem to grasp where this is helpful.

FYI I am not a keyboard jockey I don"t have much skill with computers, spelling, typing and proper names for a part of a vehicle. I am a Second generation mechanic. My father worked in heavy repair his whole life where I have learned from him and all the other old time mechanics through out my life. I am not school trained, everything that I know I have learned in the field from experience. my videos are just for information and are made in hopes of helping out only, you should do your own homework and only try to do things that you feel that you can complete.

I know this is an old video, but it just saved my a**. I was not about to take the entire air box out. Buddy came over with a 4" angle grinder and it worked like a charm. Just barely enough room for the new heater core to fit, but it worked and now I have heat again. October in Denver is getting pretty cold. Thanks a lot for the idea!

Its been a minute since you posted this but Man Im glad you did! Ill be “going in” this week. 👍🤘🍺

Just saved me so much work, thank you!!!

Nicely done!

Thanks for video.. been putting this off for yesrs and my mom has suffered every winter without heat.. This looks easier and epoxy should keep that plastic together just fine

This definitely saves time and money. Don't have to disconnect the AC

id use calking or liquid nails to put that back together, over time ive seen epoxy and glues fail when messing with cooling and heating systems. to many temp changes causes most stuff to fail.

Awesome trick. Thank you for sharing!

Great work thanks for sharing!!

worked for me !!

Genius, thank you

I already took it all apart. But im gonna give this cheat a shot to get old one out and new one in.
