93 SSEI WITH 117K MILES RUNS GREAT! BUT....THE AREA I LIVE AT THE TEMP IS ALLWAYS HIGH BETWEEN APRIL AND OCTOBER OUR LOW IS 78 OUR HIGHEST UP TO 120) SO I CHANGED THE THERMOSTAT TO A 180 BUT THE FANS NEED TO COME ON SOONER THAN THE 230 FACTORY SET. ANY IDEA ON HOW TO PROGRAM THIS? WHAT SHOULD BE THE APPROPIATE OPERATING TEMP?
ALSO, MY SUPERCHARGER BOOST METER SHOWS ON THE NEGATIVE WHEN IDLING THEN GOES UP A BIT TO THE MIDDLE AND DROPS AGAIN. WHAT SHOULD IT READ? I HAVE AN 89 BONNEVILLE LE THAT RUNS GREAT AND FANS TURN ON AT 195. NEVER GETS HOT. HOW DO YOU CHECK THAT THE SUPERCHARGER IS WORKING IGHT?
I WOULD APPRECIATE ANY INSIGHT.

1) Can you get your CapsLock key unstuck? You're shouting at us...

2) The fans should be for auxiliary cooling rather than all-the-time running; have you flushed the cooling system recently? You shouldn't be routinely seeing a 230º reading on your gauge just while driving around. For that matter, you've verified that both fans really are coming on sooner or later, yes?

As you describe. That is, you can't get on boost while you're sitting in Park; you should (and apparently do) see a wastegate opening to dump boost if you're revving it in Park, under no load. It sounds normal to me; you should see boost assist only when you're driving along and get under moderate to heavy acceleration. If it'* going into positive boost just while you're putzing along at 30mph, something'* not right...

http://www.bonnevilleclub.com/forum/...ic.php?t=16737 for the cooling fans. Re-programming isn't an option unless you install a variable temp controller.

Just run a switch to control it as you wish.. if thats what you want...

THANKS!
I SENT YOU PM INSTEAD SORRY. YOU ARE GREAT

DO NOT DO THIS! When your PCM commands the fans on High, you'll have 12V going head to head!

DO NOT do it. GROUND the high speed fan control relay instead.

I think willwren is correct. That'll supply 24V to the fans. Not good.

*cough*

You sure about that?

Parallel, not series

I FOUND A SERIES OF FAN SWITCHES AT PEP BOYS RANGING FROM $29 TO $49
THEY ALL USE A RELAY AND SOME HAVE ADJUSTABLE TEMP CONTROLS AND SOME ARE SET TEMP. I BELIEVE THAT ONE OF THESE KITS, SET TO 190 SHOULD WORK. THE COMPUTER WILL NEVER TURN THE FANS ON EXCEPT IF THE SWITCH FAILS AND THE TEMP REACHES 230 IN WHICH CASE, THERE WON'T BE ANY VOLTAGE SUPPLIED BY THE AFTERMARKET SWITCH TO THE FANS. SOUNDS GOOD?
