2010 Tahoe PPV

[rmuszynski]

Just picked up 2010 Tahoe PPV with 250k miles. Pleasantly surprised it had a GM replacement tranny, was a former MD State Police cruiser. Currently installing all new brakes, shocks/struts, trans and coolant lines.
Curious has anyone ever removed the rear A/C-Heat components, seems redundant in this. Not sure if worth the trouble.

I like to simplify things too..

But I have heard the A/C will struggle in hot climates without the rear.
There was a recent thread about the lack of rear heat, and it was cold for the passengers..

Besides, the rear heater should add some extra cooling system capacity right?

Good point, i had not thought of that.

I have had several Suburbans, Yukons, and Tahoes with rear heat/ac. If it is hot or cold, you will want it to work. There is no benefit in removing it unless you are building a race car.

Welcome to the forum from Coeur D'Alene, Idaho! Congrats on the Tahoe.

I'm putting the rear heater out of service when I do a coolant flush. Removing the tees at the firewall and going straight into heater core with the hoses. The AC is different. Probably take a little soldering to omit it...(plus a pumpdown and refill of refrigerant.) Think I will leave it alone for now...also...I intend to hook the heater hoses directly to the heater core pipes that stick out of firewall. I think the plastic fittings are a weak point Will use new heater hoses also.
Good Luck

Appreciate the feedback, I am going to leave in place and focus on other areas.

Those plastic heater hose fittings work fine until they don't. Lol. They don't intially catastrophically fail though, they will leak first giving you plenty of warning. I think I replaced mine around 150k (204k now) so they have some longevity. If I remember right, they are incorporated to the hose. Some guys change the ends to standard fittings and hose clamps.

Part of the reason I bought the dorman hose, the ends have spring clamps and you could replace the hose section by itself, even though its the plastic that will likely fail first..

Also the reservoir "T" (more of a "y") is metal on the dorman.

I'm going with hose and no fittings (if it will work) Hose into the heater connections and worm clamp tight. I checked on that metal VEE at Autozone and it was $29. Don't think I need it...ha ha Only reason for needing new heater hose is that mine is gonna be short once I remove the tees going to the rear heater. (looks like) I can't do any of this now as it's too cold to mess with liquids....Nuttin leaking, so I'm good for now.
