My old fitting came out easily. Most any barb fitting would work, but I replaced mine with a brass AN fitting. I then used another brass fitting and modified it into a restrictor for the AN fitting, its the same size hole as the original GM snap in fitting. No leaks, easy to R&R if necessary...

I have a Suburban that came with a DS4 and has had a DB2 for some time now. Throttle pedal effort was maybe a bit higher when I had a fabricated throttle cable bracket when running twin thermostats and a DB2. I now have a single thermostat and the factory throttle cable bracket and its not bad...

I bought a Hayden Heavy Duty Truck fan clutch (which is above the severe duty) for $111.00. Peninsular use to sell take off water pumps with the spin on pulleys for $65, you might give them a call and see if they still have any. That is what I run on my Suburban with a Duramax fan and it cools...

I use a little white lube on the rubber seal. If the rubber seal is old, you can get a new one at the dealer for a few dollars.

My local injection pump repair shop has the oil drain & exhaust to turbo gaskets.

You should be able to find an Earl's or Aeroquip dealer in your area. Both should have everything you need to fabricate the hoses. All of the large online speed shop places have them (Jegs, Summit). Another source is an industrial hose dealer. I suggest you change the oil cooler to one with...

You can get Hella relay mounting bases HERE . These do not come with terminals, so you need to order some of these as well. These terminals solder on to your wires and snap in the relay bases. Typically each relay uses 4 terminals, but I suggest you order a few extras. Once you get it all...

I'm certainly no expert here, but its my understanding that the motor works or it doesn't. I would look at the control head before you change the actuator. You can get to the wire for the actuator without too much trouble and make sure its getting the proper signal from the control head...

Lets see, first you state that the "real only way" to make the 4L80E work "good" is a $1200 Compushift computer. When I pointed out this is incorrect, you come back saying the GM TCM "doesn't work nearly as good as a Compushift" and then express some third party information that you are really...

Probably no need for this. There was a factory sound mat behind the dash on my Suburban

Yes, I did. You can read the sordid details HERE

OK, I'll bite. Since I run one, I would like to know, what is the problem?

Its been very hot here and the engine temp runs 185-190 best I can tell. The A/C works well, so I would say the fan & clutch works fine. Even in 95+ temps in traffic, the engine runs cool and the A/C puts out cold air. I have not done any towing, so I can't say how it would work there. All...

Looking at the tube to the dryer, which is actually the end of the evaporator, you have little choice but to replace the evaporator core. I have been there and done that and it ain't no fun! While you are in there I would go ahead and change the heater core as well.. And a suggestion from...

Sorry, gotta raise the flag on this one. :icon_bs: DB2 compatible 4L80E trans computers can be found for $100-150 very easily - sometimes even less. And these give factory reliability and shifting because they are GM parts! It really is not that hard on 2WD autos to convert. A little harder...

I have the Kennedy set up and it works great. It is a little pricey, but its completely plug & play. Its also nice in that it has a small button that energizes the pump. Makes it easy to prime the fuel manager after filter changes, etc. Its mounted on the firewall, about in the middle...

I don't know how this thread shifted into a small car discussion (bashing?). Anyway, I do have a bit of experience in this area. I have owned and driven/ridden in a Mini for thousands of miles. Now I'm talking real Minis, not the new ones. They are almost exactly 10' long, so most would...

A friend of mine is an Earl's distributor, so that makes it easy for me :smile5: BTW, the truck cools fine, even with the horn in the way. Maybe its the additional airflow from the WT grille! ):h I always wondered why GM put one horn there and the other behind the LH battery :confused:

As you found, the DB2 has a completely different fuel inlet than the DS4. Depending on how much work you want to do, there are several things you can do to increase fuel supply. The fuel inlet on the head of the DB2 is not real large, so that is a limiting factor right there. I have been told...

Buying a complete kit does make it easy, but there is really no reason you cannot source everything you need to install new lines. Here are some pictures of my new oil cooler setup. It looks like Barry used straight hose ends with an extra 45 degree adapter. I used 45 degree hose ends...
