wtf was gm thinking... heater core

87c10slammer · 01-27-2009, 03:32 AM

how many of you guys have ever changed a heater core in your trucks... i personally own a 00 jimmy bu tthe truck i am talking about is a 99 jimmy 4wd 2dr... what a pita.. gotta take the whole dash out, then a/c unit under the hood, then that stupid black box that souronds the core itself.. all for 3 little screws... i mean really wtf... i was so mad... i spent all day sunday into monday doing this... let alone it was below freezng out all day... and i was outside cause my c10 is occuping the much needed garage space... my buddy caled me up saterday night and asked me if i could do it for him and i stupidly said yeah... so sunday morning i stopped by the local pick a part and saw what i was in for and almost cried..lol but now its back together and i must say the heat works great now... i still dont know what gm was thinking on that one though... i could have delt without having to remove the a/c box

ya i hated doing it, i had to do it to two of my s10s, and now my blazer is smelling like coolant

my S10 is in the garage so im not changing mine until spring lol

yeah i would have moved the c10 but it doesnt have a rear axle underneath it... and the frame is half cut for the notch

It would have been easier to bolt a 12 bolt on the C10!!

87c10slammer · 01-28-2009, 09:56 AM

yeah it would have been easier... but its in a frame jig.. basically in peices and a pita to move anywhere...

have you tried changing cores on other vehicles....its not easy on any vehicle. ive changed my moms dodge durango's 3 times in 10 yrs. now thats a pita

87c10slammer · 01-28-2009, 12:26 PM

yeah i have done probley a dozen or so of them... this was the first time i had to take out the blower motor and all from under the hood... normally i just lay on my back and take it out without having to take the dash and crap out... sometimes jsut the center console but im pretty good with getting things done in a timely manner... it jsut baffled me how rediculous it was

I never did it before but I got it done in 9 hours. Now that I know which/where the screws are I would estimate about 4-5 hours.

my buddy can do it in three without taking the dash out but he's done a bunch of them

87c10slammer · 02-01-2009, 08:40 PM

yeah im sure it can be done faster but im not use to doing al that crap... i wanted to shoot someone when i got the dash out and all the visible bolts onl to find out there are more outside the truck... not exactly fn to be seaching around for mystery bolts in the cold ass weather

when i worked at the chevy dealership the guy i worked with, me and him did one in 45 minutes. for the life of me i now cant remember how he showed me, but when that time comes, i will definately be calling him up. we partially removed the dash and slid it rearward but left everything except the A/C control unit plugged in. theres one 7mm bolt that down in that plastic box, i think thats why you gotta take it off, i learned a trick about getting it out and back in so you dont have to take the box off

87c10slammer · 02-05-2009, 02:40 PM

yeah i read about that trick after the fact...lol small hole saw and some silicone sealer.... i have only had my jimmy for about a year and besides pulling the cluster and center console to clean it really good i havent worked on the interior of thes trucks much.... i use to workin in the back on sub enslosures and amp racks...
