() Date: November 05, 2019 08:39AM I have a 65 corsa and need to remove the rear end of long heater duct. C9291R appears to be the part number from clarks. This is the piece under the engine that goes under the small plate at the rear for the tunnel. I can't seem to get the the end piece off the long piece. I have removed all the screws I can find. What am I missing? Any help would be appreciated. Thanks Larry Re: Heater Box Removal Posted by:

Thanks Larry A picture would help, but are your talking about the tunnel plastic duct? C9291r is a metal collar that goes on the tunnel duct. A flexible hose from the heater box fits over the collar. AFAIK you have to pull out THE ENTIRE plastic tunnel heating duct as it was built as one assembly. The only part that is separate is up front that goes up to the heater defrost diverter. The long plastic tunnel duct has at least two screws holding it in and a strap at the back end were the hose goes on. The duct is usually dirty and sometimes greasy. Simple Green, coat hangers and rags will clean it up. No more smelly heater. Re: Heater Box Removal Posted by:

() Date: November 05, 2019 03:34PM Thanks 66vairman. I will have to pull the entire plastic heater ducting. It looked like the piece on the end would just slip out but that does not appear to be the case. Thanks for the help. Larry Re: Heater Box Removal Posted by:

Larry Your welcome - note the back part of the duct the hose goes on has an extra plastic cover to protect the duct from road debris. The cover piece is stapled on the duct and can appear to be separate. There is a "Z" bracket attached to the rearward part of the duct that is screwed into the floor pan. I've seen a few ducts broken were the bracket is attached when folks missed the screw and tried to force the duct out. After you get the belly pans off and remove the screws holding in the duct, it should move back a inch or so and drop out. Don't wack the front end on the garage floor as it falls out to prevent cracking the decades old plastic. Re: Heater Box Removal Posted by:

() Date: November 06, 2019 06:09PM Thanks for the additional information. The screw for the screw hole you have circled is broken but the hole is fine. I just have to get the broken screw out. The z bracket is fine. The metal collar appears to be in good shape. Larry Sorry, only registered users may post in this forum. |
