  • Re: BBR's 545 83GT

    Yes, 83-86 all use the same hoods. Great price, too bad he's not local though.

    Got a little time this weekend to work on the car in between working on house projects. Saturday I got the pump mounted (after $1.49 in new, shorter bolts) in spite of the HOWLING wind we had all pretty much all day. It finally settled in the evening and it was gorgeous outside. The install was pretty straight forward, with a couple of notable issues.

    1. The lower hex bolt on the driver's side would hit the housing when you were tightening it down. This could have been prevented had I had used allen head bolts. I decided to just toss a couple of extra washers in and it worked fine.

    2. The lower pump-housing to pump-elbow bolt interfered with the installation of the bolt mentioned above. No biggie really. Pull it out, insert other bolt, and put it back in.

    3. There were no pump to plate gaskets provided. I had to make my own out of some old unused water pump gaskets.

    4. The alternator bracket attaches to the lower bolt of the water pump elbow and the bracket required some trimming to fit properly.

    Today, in spite of torrential wind and then later a light rain burst (I love the trees overhanging my driveway!), I fitted the alternator and adjusted the brackets so that the pulleys would like up. I also had to slightly drill out the mounting hole for the alternator so the larger Ford bolt would slide through. I ended up having a spacer the EXACT length I needed so the install went fairly quickly. I connected the alt to the battery with a nice 8 gauge wire I had left over from my car stereo days.

    Things to still finish:

    1. New belt - 15305
    2. New lower rad hose - 1.75 x 1.75 x 17
    3. Wire up pump relay



    Can't wait to finish it up.

    Oh yeah, I think I may have solved part of my hot start issue. When I was lying under the front of the car, I tugged on the starter cable and it appears that it is not tight at the starter. I will have the jack the car up to get to it and make 100% sure it is tight.

      Nice progress in spite of the weather - we have a wind advisorys on and off for days - I feel your pain. Sunday after church I carried a 4x8 sheet of osb down to the shed to replace a water logged piece - the wind just about took me and the osb for a ride.

        You and the OSB both? SOB! (sorry, couldn't resist)


        Looking good James. Is that low slung alt mount a factory deal or something you whipped up? I don't recall any factory low-slung alternators, only PS pumps....

        I'd like to do something similar to the alt on mine, but I seem to have bigger fish to fry at the moment. Grrr....

        I'll just have to settle for following along vicariously for the moment. Thanks!

          You said you might need a new hood, not sure if an 85 will work or if it tall enough.

            That is the factory location for 460's. Makes for a nice looking install, but it's a PITA to tighten the belt because the adjuster is on the bottom!

              All finished. Filled it up and turned the pump on....... no leaks! Knock on wood! haha Started the car and it took a while to get to 180 deg, turned the electric fan on and the temp went back to 170-ish and stayed there. OAT is 72 deg. I did not drive it though. I wanted to let it sit with water in it for a while before I ventured off somewhere.



              The alternator is apparently doing it thing too. The belt was not tight enough so I would get a squeal when I blipped the throttle and when I turned the electric fan on. Whoo Hoo!

              Only problem I noticed is that the fuel level gauge does not seem to be working. Either that or someone done jacked my fuel! I'll have to check the wiring diagram to make sure something in the old alternator wiring does not need to be connected to 12v.

                huh noramly when senders fail they go to over full. tryed putting gas in it to see if it moves? maybe some one did steal your gas

                  I have a locking gas cap, so I really don't think they did. I think it's just not getting power since I removed the factory alternator and put in a 1 wire. Looking at the wiring schematic right now.

                    Oh yeah, the mechanical pump was making about 20 psi at hot idle and went up from there with rpm. The electric pump is making around 10 psi when it was warm.

                      Hopefully that's enough psi to keep the boiling bubbles at bay.

                        If necessary, I think I can increase the high side psi a bit by installing a smaller restrictor in the water neck. Right now, it's just got a hollowed out t-stat in it.

                        I will test my theory by squeezing off the upper hose and watching the pressure gauge.

                            Isn't system pressure determined by the cap on the radiator?

                            Hopefully you can go back to running a thermostat once you've determined the electric pump has adequate flow rate to keep that big mill cool.

                              The more I learn about cars, the more I realize I don't know much about cars. Cooling system pressures is a prime example of that. I always figured it was all pretty much at the same pressure, but found out there is a high pressure side and a low pressure side.

                              From the pump to the radiator inlet (or t-stat, whichever is a bigger restriction) is the high pressure side. The other side of the radiator to the pump is the low pressure side. The radiator cap always goes on the low side. The pressure on the high side can be well in excess of the cap's rating.

                              My low pressure cap is a 16, but at idle, the mechanical pump was making 20 psi on the high side. As pump speed increased, it would increase rapidly and easily blow water past a 24lb. cap in the upper hose (high pressure side). This worried me because BBF's are known for barfing core plugs and I don't need that happening.... ever.

                                AHA - thanks for the lesson - makes sense, same reason why they put springs in the lower hose, DUH, I should have realized that.

                                  It ws 94 deg here today so I got to do some hot weather driving today. Water temp got to 190-ish and pretty much just stayed there. It actually went down a bit at long stop lights. Made me real happy to see that. A real test will be driving it down the highway though. High side water pressure was 18lbs when the water temp was 190, so it does not look like I am in any danger of pushing water past the upper hose cap.

                                        So does all of this mean that THESE are a bad idea?

                                        Seems like they would put the Cap on the High side, or at least real doggone close to it?

                                          They might work fine if you use an expansion tank, but with a mechanical pump, it certainly will make enough pressure to bypass the cap.

                                          I'd rather use an electric pump, have a consistent system pressure, than have coolant bypassing a cap and then having to recover it when it cools.
