Another Successful LED Dash Upgrade

Just wrapped up another LED swap on my Silverado gauge cluster. If you will remember, a while back I put in some bright white LEDs in everything on the dash, cluster, 4wd switch, headlight switch, climate control, and cargo light switch. Some of you know that any time you put white lights in the cluster or 4wd switch, it put off a blue light because of a bule film on the back of the gauge face and 4wd buttons. So, I decided that I didn't like that, and decided to try green to see if it would blend better.

 

Well, it was a success, and the parts all look the same color now. Im glad it worked out because my only other options were to go with blue LEDs (which blinds me at night) or red (which bothers me as well because to me red means something is wrong).

 

While I was at it, I went ahead and changed out the 560 ohm resistors I used the first time, to some 820 ohm in an effort to turn the intensity down so that I can turn the dimmer up, and can actually read my odometer. That paired with the fact that the green LEDs are half the lumens as the white, really turned out nice.

 

The green is much more vibrant in person than the pictures show.

I did leave the white LEDs behind the temperature slider so that the red and blue don't look funny. I think it looks better that way than having the green mixed with red and blue.

Even swapped out the bulb in my Autometer Trans Temp gauge with a green LED replacement. In person, the lights all match very well, and actually look more like the color of the Autometer gauge.

Here are the links to the parts I used. Requires 20 total LEDs and resistors. I used 18 of the green because I left 2 of the white in.

 

Use 360 degree LEDs and the factory light diffuser so you don't have hot spots.

Resistors. The more sensitive your eyes are at night, the higher ohm level you need. Even with 820 ohm resistors, I still maintained dimmer function.

Well, I'm not exactly diggin the green. I thought it would be closer to the factory green that is used in the 07-13 trucks and SUVs, but it's not. Just too intense for my eyes. Gonna put the white back in with some more restrictive resistors and see what that looks like.

 

Might make a build along out of it and post step-by-step pictures.

well, that was a bust. I actually ended up going with a blue LED with a 1200 ohm resistor. It looks nice to me, but I ended up burning up the circuit board in my climate control module, so now I have to get a new one of those.

That sux.

When my resistor module went out on my old truck it messed up my hvac control module also. i ended up getting it off amazon. Was only $99 and mine was was digital . Yours should be cheaper.

Yeah, some places have them cheaper, but they range from $75 to whatever you wanna pay for it. I have found several that don't have the rear window defroster, but I am wondering if the circuit board is all the same. I know many of the trucks share the same wiring harness regardless of options, so Im wondering if I bought one without the defroster and swapped the cover and buttons, would it work. Anyone have any idea if this would work or not?

Nevermind. I was actually able to salvage it. I had to jump over the two lower light circuits under the fan speed dial, and ran all 3 bulbs in series with a less restrictive resistor. Worked like a charm, and saved me $100.

Well, I have gone full circle with my dash light colors. I started with white, went to green. I decided that it was too intense for my eyes during low light situations. It wasn't bad at night, but during dusk and dawn it was messing with my eyes. Decided to try some yellow, but they weren't intense enough to show through the switch and gauge faces, even with the dimmer wheel turned all the way up (brightest). Changed to blue lights, and it was awesome, but it was screwing with how my eye were adjusting to light conditions at night. So, I decided to go back to the white.

 

Good news is, I did figure out that the A/C control board isn't fried. I got it to work after all. So, long story short, I spent about $75 on LEDs and resistors, just to satisfy my curiosity and realize that I had it right the first time.

 

Oh, well. it was a fun experiment.

What white LED's did you use the first time? I just put in some that light up white but when the cluster is back together the gauges are blue. I just wanted white to begin with.

Thanks

      Wow I'm in a pickle. (Broke down truck) and a story.

      Thanks - I wasn't quite caffeinated this morning. 2:1 makes sense, turning the crankshaft 360 degrees will turn the cam 180 degrees, and had I done that, the cam's dot would be at 6 and the crank's at 12 again.   I went ahead and took the sprocket off anyway, aligned everything dot-to-dot including the balance shaft just for s&g. I'm glad I did because I discovered no Loctite on the timing sprocket bolts. Maybe it's not required, but at only 20 ft-lb torque spec, those bolts aren't in there very tight. Cleaned and reassembled with some thread locker and torqued.   A general observation: Less is more with RTV. If a little doesn't stop a leak, a LOT probably won't, either. RTV is thinly veiled revenge, in a tube...

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.

      It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.
