The starter motor really sucks the batteries down. With old or loose belts, one dry ip refilling will have those belts singing. Charge your batteries and try it again. After a charge and belt snugging up.

It was a fluke. I started cleaning the backing plate with a putty knife. I don't know if the water pump backing plate is painted or coated with something black at the factory. Whatever it is, it was solid when we pulled it off the engine a year ago. It was still solid when we put on the...

Thanks for the encouraging words. I'm frustrated with myself for not checking all these fittings when we put them together the first time. I actually did the thermostat one myself and then had a student who watched me do the other 4. The water pump backing plate just seems like a fluke...

This week has been total frustration. I came in Monday with heater hose thinking once we put them on and it passed the pressure test I could let it run for more than a minute or so. Tuesday we found the thermostat housing leak. Wednesday another psi test showed the leaks at all 4 coolant...

1985 k5 blazer head light switch. Or, pretty much any GM vehicle of that era. The silverstar star lights don't like more than 14 volts. Check your alternators. Also, depending on where you bought them. They might have a year free replacement warranty. O'Reilly's told me that when I blew both...

Back on topic from disturbing baby pictures. I had written the other day how a M1009 front wiring harness plugged right in and at least the marker lights all worked. Yesterday I cleaned up my best set of front marker light lenses and put them on. The passenger side 1157 bulb didn't work when I...

Good news, bad news afternoon. The thermostat housing has no more leaks. But while spraying I saw bubbles at the base of the coolant crossover. I checked the other side and had a few there too. I sprayed the rear blocked off crossover passages and had bubbles there as well. 5 leaks at places all...

Using the air powered coolant flush machine I was able to hear a seep at one of the heater hose to heater core clamps. But, I couldn't hear anything else with the air of the machine working. This morning we went back to the hand pump and heater hose to the ear method. Tilting the radiator...

Got the heater hoses on this morning and went right to a cooling system pressure test. With a hand pump tester, it went right up to 12 psi. I walked away after not hearing any leaks. 5 minutes later it was sitting at 10 psi. UH oh! I did the hose in the ear sound test over every connection...

Those are good number Al. While you are waiting for the injectors. Start researching 6.2 IP timing. It is kind of a black magic process with the no longer made equipment. Without it, you are just guessing. I have 4 6.2 engines on the road just about daily in my family. Each one sounds...

Go back to the fuse panel. Wiggle the 3rd fuse up on the far right with the light switch on. You will probably get lights or at least a spark as that fuse burns up. I just assumed that that you know about the black out light switch. It is on the service light setting, right?

I never really have paid attention to the difference in gas and diesel radiators. I have a '89 K10 in my class with the 350 radiator. I brought in the CUCV radiator for the Cowdog the other day and went to put it in the truck this morning. After only looking at the gasser one. Those diesel...

Al, nice to see you came in from the Yurt to post again. What controller are you using for the 4L80E? I ask because if you aren't dropping gears enough as others have pointed out, you won't have any power to the ground. How does your M35 do on the same pass empty? How would your M715 have...

Since you just want to cool the air between the turbo and the intake. I think the proper terminology is aftercooler. Since it is after the last air compressor. At least that is what Cummins calls the 4BT cooler mounted on the valve cover. However, intercooler might be appropriate depending...

M101A3 trailers have the same wheels and tires as your truck, surge brakes, pintle hook and use the same power cable. They pull awesome too by the way. Several people have taken M101 trailers and done all kinds of modifications for off road camping/living. Expedition Portal is a site that...

Each alternator should be maxed out around 14.4 volts. If you measure across just the battery terminals of each battery you will get that isolated voltage. Measuring ground to each positive terminal gets you the numbers you are posting. Same thing, just different was of reading it...

I pulled the front differential cover after posting the above yesterday afternoon. Clean oil came out and everything looks good inside. One less thing to worry about. Transmission cooling will include the following: Stock 1985 M1009 radiator that has been rodded out. B&M 28K pound cooler...

We got the entire brake system vacuum cleaned out this morning. No more DOT 3 left as near as I can tell. The rear wheel cylinders were put back together and we had the same springs in the same locations with no left overs after putting the shoes on too. Drums are now round on the inside and...

As posted above. The 6.2 oil pump really doesn't fail. Yes, anything mechanical can break and this is not a "yours will never break, leave it alone" post. They are not costly so if you want, go for it. As much as everyone mentions how bad the 6.2 crankshaft is. They really just don't wear any...

There are several threads on this site and many more on other sites about this leak. Yes, you can replace the throttle shaft o ring. However, if the IP is original or has been replaced at some time. The internal parts are the same age as the leaking seal. Maybe getting a rebuild would be a good...
