I suppose that is a possibility. But, I think that there was more air in the block itself that found its way into the heater core. The heater core draws coolant from a high point on the manifold, so it makes sense. I'm going to try to burp the core again. PITA!
-
UGH! It's gone cold again!
-
Agreed. Quite nice.
-
Exactly correct. It was the raging success of the Tahoe that killed the b-body. And the reason I never got my Impala-based El Camino SS. Ticked me off. Just a preview of what they would do to me with the G8 ST just over a decade later. One of the magazines did some very sweet renderings of what an Impala coupe and convertible could have looked like - they were very,very nice.
-
You aren't seriously comparing the Fleetwood to a Packard Hawk, are you? Talk about apples and oranges. As for the assertion that most of these cars are "rolling wrecks", I beg to differ. There are still plenty of B-bodies in quite nice condition to be had. In fact, they tend to be cleaner than other cars of that era.
-
Man, do I love A-bodies! But that color...
-
If I were to look for one of these wagons for myself, I'd hunt down a solid color example without the damn woodgrain.
-
Just to give a bit of perspective - the actuator that I was bitching about is located just to the left of the fan in a very narrow cleft of the fan housing at the back and up. Use a little imagination and you can see what a drag it was to get to.
-
I don't know, it would be very easy to replace. I think it could be done in less than a half hour.
-
As promised, here are a few shots of the heater core before I buttoned everything up. It mounts at a 45 degree angle upward from where the inflow and outflow tubes are (bottom right). Easy to see how air got trapped inside.
-
Well, the problem was the core - just not the same problem initially thought. This poor Tahoe had so many problems within this single system that correcting them was bound to be a drawn-out affair. I have to tell you, I feel pretty good about conquering it. But I still have a laundry list of other things to fix, This truck will keep me busy for some time yet. For now, I have heat and my interior is back together at last.
-
Thanks for being sounding boards for me during this repair, guys - it is much appreciated. Now for some sleep!
-
Yup. I may take a pic of the heater core after i secure it in place again - you'll see why the air got trapped int there.
-
Well I'll be damned, it worked. I have heat.
-
Exactly, that's why I think the small passages are plugged. I'm not tired, and it's only one fastener, so I think I'll try to "burp" the core right now - then go get a snack and see what happens.
-
That's what I've been thinking - but it seems so odd.
-
I can see and touch the entire core - it has a few warmish spots, but no hot ones. Yet flows water like crazy when I put the hose to it - didn't even notice any crud coming out during the flushings.
-
Couple things I forgot to mention: - There was debris in the ductwork that had passed through the fan and lodged against the A/C evaporator, the shop vac took care of that. - And, the Tahoe is running better than ever after tightening the intake manifold bolts. More power, better idle, hopefully improved mileage. I'll get to the bolts I couldn't easily reach after the HVAC issues are solved.
-
That C3 is still in play - I'll post if/when anything happens. The water pump seems to be working just fine - truck runs nice and cool, no noises or leaks from the pump. No collapsed hoses - all look good visually. The core sits at an odd angle though, I'm going to loosen its mountings in the morning and drop it to a flatter position just to rule out air pockets. But it is already lower than the rest of the cooling system (except the very bottom of the radiator). It's a stumper.
-
They usually are. This one is in a most logical spot. The actuator was the big PITA of this whole affair. My only worry is that the damn core flows water so well that I am doubting myself a bit. But I can't think of much else that could be keeping me from heat at this point.
-
Actually, it's easy. And cheap. Nothing compared to getting at that actuator! I think I could do the job in less than an hour (if I had the part). Has to be the most accessible heater core I've ever seen, has its own access panel all the way at the bottom of dash at the floor.
-
Yes, quite well in fact. I think that all of the small passages are clogged and the water is just running through rather than heating the core. It really is the only variable left. Didn't get hot on my trip to Pep Boys, and the core was out of stock. Oh well.
-
I just finished replacing the thermostat (no change noted). So I think I'll take it for a cruise to the local Pep Boys. If it doesn't heat up in that time, I'll see if they have a heater core in stock.
-
I've already done that repeatedly.
-
I don't know Balthy,I was just going to post that I'd pick "any plane from WWII" !
