Doing the replace everything theory of lowering my gauge/LED temp. Next on
the list is to replace the radiator due to flow constriction discussions of
late. I read in Bentley there is a LED computer unit somewhere, but have
seen little in the achieve on this topic. Anyone have experience?

Got the van 6 months ago with temp gauge on 4/8 dead center for a month

Then it dropped to zero, replaced sender unit which got the gauge back in
working order

Ever since the sender unit was replaced it has been at 6/8 with intermittent
LED flash in stopped traffic

High/Low fan is working up front and can force flow with turning on a/c fan
(not compressor)

Replaced gauge sender twice to double check output

Replaced thermostat

Thermal gun shows acceptable temps at thermostat housing and hoses (180
degrees F)

Can check voltage at gauges but from what I have bad voltage there often
causes low readings of the temp or fuel gauge not high.

The reason I ask about the LED box is that the LED will continue blinking
after starting unless I hold the ignition in the accessory position for a
bout 5 sec. then the blinking LED (test mode) will go out after starting. If
I attempt to start it right away the LED will continue to blink. The coolant
level sender has no affect on this no matter what I do with it and I have
cleaned the contacts and tested both will full continuity and no continuity.
