    New crate motor with Edelbrock intake and q-jet. Runs awesome. I questioned the stock guage (no numbers) and installed an AutoMeter, but put the sensor in the intake manifold instead of the head (cause I did not want to make a huge mess) and am noticing the temp running at 150F. I have a new (the 2nd one) 180F thermostat. Do I need to relocate the sensor to get the correct temp or is something else wrong? (thermostat stuck open?)

    Thanks,
    Mike

    Hey,
    I've noticed that a good spot for that sensor is on the drivers side of the block, inbetween the 1st and 3rd cylinder. lower than the spark plugs. My friend put his in his edelbrock intake and it did read many degrees cooler. The aluminum dispirses heat quicker and will give a lower temp reading. also, that sensor is closer to the direct radiator flow. (the colder coolant mix is going to hit that sensor faster). that's all i can think of.

    Haviong it in the manifold, especially by the thermostat can cause it to read incorrectly. I just moved mine from there to the head location and all my temp guage weirdness vanished!

    I started with nothing and I still have most of that left! - <a target="_blank" href=http://24.55.50.76:81/k5/> Pictures</a>

    Thanks for the tips. I will move the sensor and see what happens. I just did not want to make a big mess. I am getting sick of coolant.
