Its been a couple of months since I last posted on this. The Suburban is running great. I have had a couple of minor problems, but nothing too bad. First, I had a leaking hydroboost.
You can see the fluid leaking here. I replaced it with a new unit.
The other problem was a minor engine...
In the 15 years we have owned our Sub, the CS-130 alternator has been a source of trouble. I have taken it to a local rebuilder every time it had a problem. Early on I had an iceberg rear housing installed. Had to rework the mount slightly to make it fit. Lets see if I can remember all...
The oil analysis is about $25. I use this place . It will give you an indication and might tell you of any problems, but will not guarantee you a trouble free engine. I bought a "good" used 1997 506 block (guy took it out to install a Cummins, maybe a bad omen?). Sent in a oil sample from...
I have recently rebuilt a military surplus NA 6.5 for our Suburban. Given a choice, that is what I suggest you start with. You have to be careful, as lots of the turbo 6.5's are center turbos. While that will work, the heads and manifolds are different. So putting one in a truck with a...
That is not exactly how it works. You don't use the PCM for the cruise and its not vacuum, its electronic. You would need a factory (or aftermarket) cruise stalk if you don't have cruise now.
You use a Delphi or AC Delco cruise box, like this one. Self contained, all electric, no...
I guess its hard to say why they did it. Seems like they could have got the same redundancy with three even scales. In any event, it pretty well eliminates using the PCM with a single APP input.
Not easily. I think GM was worried that the APP failed, someone would just jump the wires and be able to use a defective APP. My guess is they were worried about runaway acceleration. Anyway, it uses 3 differently scaled APP inputs. They must match or it sets a code. So that is why you...
Yes it will run on two. I don't know how you would get two TPS synched up. The DB2 has a mounting for one TPS. Don't know how you could fit two on there.
Its been a while back and I don't remember exactly, but I did a lot of experimenting with various configurations when I did my conversion. I did try using the TPS to replace the APP inputs. I bought a PROM burner and the software from Westers and made lots of different PROMs to try and get it...
Yes, with the GM standalone TCM you use an engine speed sensor, which is a bolt in replacement. Needs a TPS as well. On 2WD, you use the same DRAC and VSS. Really, you use all the same trans sensors. Just some rewiring, as you retain the PCM as it still handles some functions. Glow plugs...
You can use the existing PCM by cobbling up throttle pedal with an arm to actuate the APP, but I have never seen one shift correctly. You can get it to work OK, but not perfect. Synching up the pedal with the pump and the APP throughout the range is just not possible. I spent weeks trying...
Pump - I know others have used a 6.2 DB2 (.029" plungers) with success. It will not match the larger .031 plungers, but if you turn it up it should be OK. It will not harm anything and you can always change it out later if its not powerful enough for you.
Lines - Use the lines that are...
Yes it makes it much easier to get to. I had to lengthen the wires, but since you are cutting some of them to add the relay, its no big deal. I did keep the original brass fitting at the block as it has a restrictor and it allowed me to use a straight hose end. I think its 1/8 pipe, maybe ¼...
I remote mounted my OPS. I also have the Kennedy lift pump controller, so I have two oil pressure switches. The factory OPS is still connected and runs through a relay, but is not currently powering a lift pump. Should the Kennedy unit fail, I could plug it in and use it. One of these days I...
