Hi folks,
Assuming all is working properly in my cooling system and I want to adjust the gauge reading...anyone know which direction to adjust the small screw in the GW product to lower it?
Thanks,

Hi Brian,
A useful trick when adjusting something with a screw is noting how the screw is at the beginning, and adjust through 1/2-turns steps.
For example, once your van is at temp as per GW's kit instructions, turn the screw one full reolution (one full turn) clockwise. See how the gauge needle reacts. If nothing, keep going, another revolution. At one point the needle should be affected, and you'll know in which direction.
And with this trick, at any point in time you can come back to the original settings. in our example, if you go back two revolutions anti-clockwise, you'll be back where you started. _________________ '90 Little Blue Truck, 2WD auto, FAS GenV 2.0 NA (AVH) |

The full adjustment range is less than 1 full turn! (3/4)
Full counter clockwise is maximum "adjustment" toward a lower needle position reading.

Just made the adjustment and it was at the "high" setting. I'll see what happens next text drive. It's fresh stock rebuild and my rebuilder suggested it likely has a good ground for the first time in a long while.

Update!
The adjustment is actually counter clockwise on mine to get a lower reading on the needle. Full clockwise got me a needle spike and blinking light. There was no overheat issue at all and once I made the adjustment all was fine.

How did I read that, that many times wrong.
Sorry man.

How do you calibrate the temp? In other words, where are you taking the temp reading? I was just shooting an IR gun all over the place, hoses, radiator, etc. and for such a variance, even on feed to radiator at diff places, that I’m
Not sure what the “true” reading is.
Further compounded by the reflectivity of the surface affects the reading. _________________ John - 86 Wolfsburg Westfalia "Weekender"

Honestly I'm assuming a lot with my readings. The engine has been rebuilt by an expert rebuilder so my confidence is extremely high. When I adjusted, improperly, the resistor from GW it was to just get a lower reading on the needle. When it spiked due to adjusting it the wrong way the engine wasn't hot. It was over 30 Celsius here yesterday and I could put my hand on both hoses at the thermostat housing. Adjusting the screw the proper way to lower(counter clockwise) the needle has it just below or touching the light.
I haven't done any IR readings and everything is based on running this van and a stock engine for 12 summers.

Yeah, you are likely fine, in the case of those with engine conversions (and some with stock WBX), it would be nice to know the actual temperature in F or C. _________________ John - 86 Wolfsburg Westfalia "Weekender"
