Another thread got me thinking about my fan. I just ran around for about 15 minutes and temps never went over 190* (according to my ScanGaugeII). When I got back in the driveway (temp at 186*), I popped the hood and saw the fan was spinning. I kicked on the high idle switch and the temp got...

Has anyone ever weighed the standard, 16" steel rim and compared it against the weight of the "PYO" aluminum rims that showed up around 2001? I assume the Al has to thicker than the steel so I'm wondering if there is actually any weight savings?

So, for a while now I've been tracking some numbers with various turbos. Although there's a couple other "tests" I've done, the main one I've been concerned with is a hill "climb", so to say. Let me start by describing my method. I've tried to keep things as much "apples to apples" and...

The fuel return line fitting (top most one in picture) is looking pretty nasty and it appears that is where the new "waterproof" spot on my driveway is from. I plan to drive it to work tomorrow and then pickup some rubber (probably not actually "rubber") fuel hose on my way home. I'll cut out...

Noticed my AC wasn't blowing cold (this was the first time I had it on this season), so I pulled over and saw that the clutch is not engaging. When I got home I removed the 2-wire plug (on the AC), cleaned the connections and re-plugged the connector back on (actually unplugged and plugged a...

I popped the drum off to take a look at things. I don't have the special retaining nut tool so I tightened it back up in a similar fashion to the way I do it on trailers - "by feel". For this nut, I stuck a small Torx screwdriver in one of the "holes" of the nut and used that to rotate the nut...

My grandmother has a 2005 GMC envoy (I apologize, I don't know the specific automatic tranny). It has approximately 15,000 miles on it. I borrowed it for a few days and noticed that the torque converter is acting up. Between 50mph and 70mph it is constantly "hunting" to lock-up. Sometimes...

With OBDII: I recently installed a new PMD (I guess it's actually called an FSD, now). Originally, there was a #5 resistor in there. Now there is a #9. Truck runs fine, but I wonder if the ECM still thinks there is a #5 in there? So, I searched for the answer... I found some answers...

In anticipation of possibly needing a new IP, I spoke with Pensacola Diesel. They mentioned they build IP's to the Stanadyne spec of 24-26cc's, usually towards the lower end of the spectrum. However, they could build it higher than that. What are your thoughts about having that done? Also...

Hi everyone. I feel a little lost. There is so much info on this site, it gets a little confusing to weed through, sometimes. I know enough about the PMD issues to have a basic understanding of the problems associated with it, but not enough to weed through all the info efficiently. I know...

I searched through the site and found good threads about this, however the most recent that I found (at least with my limited search abilities!) was about 1-1/2 years old. So what do you all think? Is this still the way to go? Are a lot of you using the D-Tech?

I've noticed oil leaking (more like seeping, than leaking) out of the area between the turbine and the compressor. It's seeping out where turbine and compressor attach to the center section - in the crack/gap where the bolts (and rectangular washers) are - I guess the "mating surface" is a...

I tried searching, but couldn't find the answer. Does anyone happen to know the size of the 4l80E (1998, if it matters) output line? More specifically, the fitting size? Are they a certain type of threads? I'm adding an extra tranny cooler (mounted under the truck, with a fan) and I...

My truck is a '98. Does this era truck have a cabin air filter? If so, how do 'ya git to it?

I hope this is OK to post this here - it's not engine related, but it does deal with a topic that appears here once in a while... Every so often someone brings up the idea of hood vents - primarily to evacuate hot air - usually not in regards to bringing in cold air. I've always been a...

Now that the cold weather is here, I've got a little fishbite thing going on. When warming up the truck, with either of the high-idle's engaged, the engine will fishbite for about 1 or 2 minutes (might happen about 20 times within that 2 minutes). If don't engage the high idle, it will not...

I suspected my block heater wasn't working - couldn't hear it when I plugged in. I put my meter on the the two prongs (not the ground prong) at the cord end (opposite of heater) and got 8.5K. Hmmm I thought. I expected to see infinity. However, I'll admit that I don't know what it should Ohm...

If you have rear heat, could you measure (O.D. is fine) the diameter of the hoses that go to your FRONT heater core? You may or may not have seen my thread about trying to get the rear heat working on my Suburban: http://www.thetruckstop.us/forum/showthread.php?t=18064 It's possible that the...

The rear heater in my Burb has been not working for about a year. But, as I don't sit in the rear, I haven't been too worried about it. But, I'd like to get it going again. I read through Chilton's, but that does not seem to have the answers I'm looking for. I also searched here, but was still...

Been a while since I posted, but I've been pre-occupied with some other stuff - mainly, boating. BUT, there's always been good discussions on here about ECM's, so I thought I'd share my experience with a new Kennedy Tune. A couple years ago I tried both a Kennedy and Heath. Very close - the...
