Hand held thermometers
The units Murf is talking about are very common here with the moisture we have. At same time the guys who really know how to use them can take the simple point and shoot units and gather the same over all info just not a showy for the insurance adjuster and homeowner who needs a picture verses a series of temperature taken across a wall.
Frank, mechanic here told me they are the best to check for clogged radiator, if there is a cool spot it is clogged. Living where you do, get you one, go out side on a cool day and take temp readings to find out which windows or doors need sealing and even can show if a place in wall is not insulated. A good way to find studs believe it or not in outside walls for hanging pictures or such. You can check the temp leaking around windows and doors from inside also.

Frank, have you ever watched a race team use them to measure tire temperature? I've never done this but theoretically you could use them to test for inflation or alignment problems. After driving for awhile ideally they would measure about the same across the tread. Higher temperatures in the center would indicate overinflation, higher temperatures at the edges would be underinflation, high temperatures at one edge or the other would likely be camber and/or toe alignment problems.

KW;
That is interesting, I'm not a regular race fan, just on TV and a few times at a track so I've never been in the pit aeria to see them used.
I do know that a half flat tire won't go too far without getting hot. I used to help my parents when they ran a mom and pop corner gas station when someone would pull in with a tire about flat that would be plenty warm.
It really isn't going to change the price of tea in China whether or not I know tire temperatures, but I'm curious enough now to get one of the hahd helds, Not the 2,500 dollar one but something more in my budget, like 50 bucks.
Frank.

The Westward unit I purchased was just over $100.00.

Frank I don't worry so much about tire temps. But if you have a strange noise maybe tire tread or soft that would help, maybe a bearing. Where I see the big value is seeing temps on brake rotors is one working harder or dragging. It will also give you a good idea if wheel bearings on the Trailblazer are going bad or is that a tire noise. Don't ask me how I know!
The other places that are handy are head tems on air cooled engines. How much hotter is the read cylinder vs the front...

Harvey;
I hate to bring up a sore subject but I'm guessing it would be the front wheel bearings. Ours has about 60K, when do they go out? By the time you hear them what else do they tear up? Did the hand held show excess heat from the outside or bebind the wheels?
Frank.

Frank on my 04 it was around 80k I drive about 35K a year. My wifes 04 now has about 35k on it they, I think, are starting to hum. I've got to check them on a longer drive other then her short brake burning trips to town.
I know the sound and am confident hers are making noise. The bearings which are assembled in a hub are around $300 each. If I remember right.
I never did a baseline of the good bearings but you have to go in from the back to get the hub. Check L & R to compare. I suspect you will hear they long b4 u check 4 heat. But the heat will help isolate the problem area.

You can also check wheel bearings after a few miles with your hand. The hubs should not be so hot you can not place and hold your hand on them. Don't think they should really be hot at all. Will say I have done this often with trailered bearings but not sure on vechile bearings.

How do you use it to check the grass?

Healthy turf will be growing pretty vigorously and as part of that it transpires a lot of moisture, that has a cooling effect. It will also generally be drawing water up from the topsoil and be fairly thick and lush.
Less than healthy turf will show up as hotter spots, both during the day and well into the evening. In fact at sunset the temp. differential becomes very apparent since the healthy grass will cool off rapidly once out of full sun. Weak grass is thin, and allows sunlight to penetrate to the earth below and heat it up. This is a double whammy, the grass is weakened further by heating the roots, plus the sunshine on the earth speeds the evaporation of the water the grass needs.
Best of luck.
