Has anyone found a good engine temp gauge for the 400 AC? I just purchased my ATV and I want to know how hot that antifreeze is when I'm riding.
I also want a fan switch that only runs the fan when the engine is hot enough to need it.

Thanks for your advise.

I am not sure who makes the best temp gauge. I know that Highlifter sales a kit. Seems like it was around $100. My brother-in-law works for AutoMeter. They make the gauges for NASCAR. He got me one of their smaller units with a 3/4 read out (meaning that the numbers go 3/4 the way around that gauge). I haven't installed it yet. So I can't give you any temperature readings. I should have it installed within the next few weeks. Summer time is too busy for me. I just work hard and ride hard!!!! [img]i/expressions/face-icon-small-happy.gif[/img]
For the fan switch. I have installed an on/off switch. I just turn off the fan when I cross deep river crossings. for me the fan is so quiet I don't even hear it running. It would be nice to have it temperatured sensored. Let me know when you get it done. I would be interested in knowing how you did it.

 

Grizzlyrules has the High Lifter temperature guage that sells for $89.95. The way his was installed ( you have to cut into a hose to install the sensor-- you can cut into the return or feed hose from the radiator-- its your choice) he is telling me his runs at around 115-125 degrees. So, that HAS TO be from the return of the radiator if you ask me.

 

What about the temp switch from earlier Cats, my buds 99 500 fan kicks on & off according to engine temp. Let me know how you make out as I think a new 400i is in my future.

 

There is a reason they removed the temperature switches, they fail. Mine failed causeing my fan to almost never run except for when going up an incline while hot. So,l I had it wired direct and I installed a fan switch later.

 

They went back to the temp activated switches on the 02 models. I liked it on all the time, but with a switch to turn it off in the deep stuff. The 02's seem to run a lot more ( come on at a lower temp ) than my old 98 did it hardly ever came on.
