Zimm63 Posted April 26, 2019 Share Posted April 26, 2019 Does anyone have a picture showing the routing of the heater hoses across the top of the motor? I have a 3/4 hose running from the water pump across the top of the AC bracket (where it is pinched by the air cleaner) to the connection of the heater core. There is a 5/8 hose from the lower heater connection under the AC bracket to the connection point on the crossover. The valve has 5/8 in and out. Should both hoses be 5/8? Should both run under the bracket? That would require a sharp bend at the front. Link to comment Share on other sites More sharing options...

The T I spoke of is supplying vacuum to the booster. Link to comment Share on other sites More sharing options...
RivNut Posted April 26, 2019 Share Posted April 26, 2019 Here are a couple of pictures that show the correct routing for a 63 Riviera. These pictures show the clips that fasten to the valve cover bolt to keep the hoses next to each othervas they lie on the intake manifold. 1 Link to comment Share on other sites More sharing options...

This is not how it came from the factory. 🤔 These pictures were taken shortly after I purchased the car. No claim to complete authenticity or factory correctness was given or implied with the pictures. I used these pictures as they were the only ones I had without the air cleaner on that showed the heater hoses. This has since been corrected. The "engine compartment hose" police appear to be as vigilant and tough as the "valve in the wrong place" police. Once again I have eluded detection long enough to get the problem corrected. Thus, escaping what could have resulted in a fine and/or imprisonment had I been discovered. Bill P.S. Shouldn't that read "fastened to the yhppthe bolt" ? What is a "yhppthe bolt"? Is that specific to the 63 or is it used on other models as well? Edited April 26, 2019 by Riviera63 revise text (see edit history) 1 Link to comment Share on other sites More sharing options...

Zimm63 Posted April 27, 2019 Author Share Posted April 27, 2019 Thanks for the pictures. Exactly what I needed. From what I see, both hoses should route under the AC bracket which means I need to tighten up the bend on the 3/4 inch hose. I swear I had that clip among the debris left in the trunk by the previous owner, but did not locate it in the box o Buick stuff I thought it might be in. Need to look more. Another question is raised by the pictures. What is the device that looks like a mini vacuum canister that pushes on the throttle? Mine was not installed and appears to be broken. Is it some sort of idle control? Where can I get one? Link to comment Share on other sites More sharing options...
RivNut Posted April 27, 2019 Share Posted April 27, 2019 (edited) I think you're referring to the dash pot. It's a device that eases the throttle blades shut so they dont close so quickly that the engine would starve and die. Once the blades are eased down, the engine will run on the idle circuits. The dash pot is a pretty universal item. When you find one, one of the parts vendors should be able to provide you with the proper bracket. It takes only one bolt to secure the bracket to the intake manifold. I just checked and there are a number of NOS dashpots ones on eBay. Make sure you get the correct bracket for your year engine.

telriv Posted April 27, 2019 Share Posted April 27, 2019 Zimm63, Go to an auto parts store & see if they carry a 5/8ths. & 3/8ths. heater hoses with the wire inside. You can bend them in ANY direction & they won't kink when going around tight bends & WON'T collapse. I used them on my '64 & have been on my car for at LEAST 35+ yrs. I don't know if they are available any longer. Tom T. Link to comment Share on other sites More sharing options...

Riviera63 Posted April 27, 2019 Share Posted April 27, 2019 Looking for some help with the brackets on the passenger side valve cover. The first picture is of my engine. There is a bracket on the passenger side valve cover. Can anyone identify what this bracket is for and if it is supposed to be there? In the second picture of Ed's engine you see a bracket in that same location that clamps the heater hoses together. Should my car have this bracket instead of the bracket that is there or is this bracket only used on non-AC cars and not on AC cars? My car is an AC car. Any input on this is appreciated. Thanks.

RivNut Posted April 27, 2019 Share Posted April 27, 2019 That bracket goes on the other bank at the rear. It holds the power brake booster hose. You can see it in the bottom picture. A steel line runs from a port at the front of the intake and across the valve cover -held in place by your mystery bracket - where it is joined to a hose that is attached to the power brake booster. The bottom picture might not be the most aesthetically pleasing but everything is right and where it belongs. Link to comment Share on other sites More sharing options...

The bottom picture might not be the most aesthetically pleasing but everything is right and where it belongs. You might be right. But, if I remember correctly that when I installed the correct metal brake booster line and the associated parts I had thought of that. I had gotten a bracket to hold the the metal brake booster line from a vendor. Again, if I remember correctly, I compared the two. While they were similar they were not the same and I installed the other one to hold the metal brake booster line and left the one where it was on the passenger side. Is the bracket in your picture above that holds the heater hoses used on AC cars? If you look at one of the pictures above that shows the 2 braces for the AC compressor, there doesn't appear that there would be room under those for the bracket.

RivNut Posted April 28, 2019 Share Posted April 28, 2019 Neither of the pictured engines is from a car with a/c. If either of those cars would have had factory air, the brass fitting coming out of the intake manifold would have been a "TEE" with one half going to the power brake booster and the other half going to the a/c controls. So a front bracket on each of the pictured engines is correct. Link to comment Share on other sites More sharing options...

I am not associated with any police department and have no enforcement powers. In your case I was just stating the facts of the situation, not enforcing. I think what has happened is that when the "valve in the wrong place" police showed up in another thread it emboldened other policing agencies to begin operations. I think we all have to be very careful. Bill Link to comment Share on other sites More sharing options...

Chuck, There is a metal line for the AC that runs along the bottom of the fender liner. What I did was zip tie it in a couple of places along that line before the lines disappear into the firewall. That metal line is fastened to the fender liner by some rubber lined metal clips which screw into the fender liner. See my first picture. What I had thought of doing was just buy larger versions of those clips to accommodate both lines for a cleaner look. Bill Link to comment Share on other sites More sharing options...
