Very big thanks to James@motorsportdevelopment!
for promptly sorting my ecu out, im very impressed by the sevice from msd, i alway use them on ebay and have spent lots of money with them over the last 5 years but this was an fault issue with my ecu rather than a straight purchase and the service was top notch aswell too.
many thanks again

All 3 switches did different things.
First one on about 92 and off at 70
Second one didn't come on at all (upto 102)
Thrid one came on around 97 and would not turn off with the engine running (had to turn engine off then wait for fans to stop then restarted engine) off about 68.
My original switch comes on at around 89 and off around 75, has done for years and still does now after refitting.
Also i used a second capilary gauge in the rad just above the fan switch to get another coolant reading as my capilary is in the engine block. Both gauges show just a 3 degree difference in temp throughout the heat range.

steve, reading the data on the webshop
Uprated Radiator fan switch for All Sierras.
This switch will usually switch on your fans at around 90 Deg C and Off again at around 87Deg C
it doesnt seem in your case you will see much benfit from an uprated switch if you do not have any exesting issues with your standard switch? why exactly did you want one mate?

Have you managed to test the switches ?

the switch will always go on/off at the same temp as it is not a variable switch,
but the time it takes to cool down enough from turn on to turn off will be effected by air flow, if your fans are on for a long time maybe they cannot draw enough air through?
our switches are designed to reduce fan run time, and ive never had one try to bring the temps down as low as yours though.
if they are bringing it down to sub 75 degs, the stat will be closed! and then the radiator has no coolant flow
im working on a car now, which i will test your switches on with our test gear,

James has just filled me in on this issue your having.
I have sold a lot of these and the only isue i have had is one that would not turn off ever. So failure rate so far is around 1 in 600.
For you to get THREE that dont work is not impossible but unlikely for sure.
Ref your coolling logs, the std YB fan switch shouldnt be switching out at 75 as the thermostat regulates at around 87 so teh engine should never get to 75 mate.
In a nutshell, it sounds, from a distance, like you have blocked radiator cores causing random end tank cooling performance. Is the radiator a recent one?

Why would the 3 switches you sent me all show different temps ? They was tested in my car a couple of times and each switch performed the same on each test.
