I've got a '02 Trailblazer that I'm doing an engine swap on, I've got a dead hole #4 cylinder. The heater hoses snapped off when trying to remove them from the heater core. They were as brittle as can be, I guess they should be with 210K on the odometer. Per every website I've been on these hoses are no longer available. Hoses from a 2003-2009 are still available and seem to look the same per the illustrated parts catalogs I've looked at online.. I'm sure GM did a redesign from the first year model I have. I also checked heater core part numbers for the two years and they are also different, hmm. The part numbers for the fittings that screw into both sides of the engine (items 3 & 7) are the same and the fitting that snaps onto the inboard side of the heater core (item 8) is also the same. Here are the parts catalogs I'm looking at, 2002 vs. 2003. I was wondering if anyone has run into this and or has any info that will reaffirm my suspicion, that '03 hose assemblies and hose parts would work on my '02. Any kelp would be appreciated.
