For all of you running a temp guage, please let me know what temps you are seeing on your guage and where your temp sensor is located on you teryx. I bought a lovorski marine guage with the black rhino sensor kit that is to be installed on the upper hose where the water is flowing from the motor(which means the water has been through the motor and has gotten hot and is going to the radiator to get cooled). I would think this would be the hottest area the water temp would be and that after it travels through radiator it cools down, then enters the motor at a cooler temp to cool the motor and as it travels through it gradually gets hotter. My temp guage says 240 and the fan kicks on and it goes to 230 and fan goes off. The dash guage never flashes telling me it is hot. I do not believe the motor is hot , but do think the water is finally that hot once it gets to the radiator. With all that being said i was wondering where others sensors are because i think if i had my sensor in the motor i would see cooler temps on the guage. So many people are posting temps of 190 up to 210. When i run down the street and it is 55 degress outside it goes down to 210. I have a stock 09 teryx with muzzy pipe as far as engine mods and have just order the impellar from hunterworks to help in cooling. Sorry for such a long post. Thanks for all support.
