i had same prob,
i know alot of people are going to repy t this ansd say dont do it,

take ya fan temp plug off engine and cut plug off, join wires together, and ha presto, u got cooling fans when ever ya ignition is switched on,

some people are now going to reply sayin engine wont reach optimum temp,

all i can say in my experiance is it worked for me, ran better and stoped blowing head gaskets
