Thermometer: Tips for Hassle-Free Shopping
You surely don't want to freeze inside your car especially during the peak of the winter season. At times when you feel you fingers getting numb, just adjust the temperature reading in your thermometer and find yourself back in summer. But what if your thermometer is damaged? Or, perhaps, you just don't have one inside your car? Before you get into a blow-breath-to-your-fingers condition, have this important utility and drive snugly down the road under any weather or season.
Location of the thermometer
Since you will likely need more than one type of thermometer for your car, it is important that you know where these gauges are installed. The location of thermometers differs from model to model, as well as whether they are for maintaining the inside temperature of the car or reading the temperature from the outside. Front-bumper and rear-bumper thermometers allow good access to outside conditions, and their distance from the engine prevents inaccurate reading caused by engine heat. Thermometers may also be found on top of the side-view mirrors, allowing them to provide accurate readings without being affected by heat from the engine and electrical components. Still, some are located under the car, but these thermometers are subject to concentrated heat from the exhaust system and the ground, which affects reading accuracy.
Specs of the thermometer
Modern car thermometers offer a lot of features to provide drivers ease of use and accurate temp reading. Buy a thermometer that displays both Celsius and Fahrenheit scales so that you can somehow compare one with the other (plus you gain added knowledge from that as well). Another feature to look for is light-up digital display, which makes such thermometers compatible with modern car interiors. There is also what we call an emissivity level capability, which lets the device give you data on the infrared energy emitted by an object. A scale of 0.1 to 1 is already good for ensuring accurate heat reading on various surfaces, from shiny mirror to blackbody. The ability to measure specific areas is also a plus; buy one with at least 15 to 1 target ratio for a more accurate reading of small surface areas at greater distances. One important feature to have is
freeze alert so that you will be notified in case the temp inside your car suddenly drops. Other miscellaneous specs are auto power off, auto data hold, easy mount with hook-and-loop fasteners, and maximum and minimum recording.
No-Sweat Car Thermometer Replacement
Your car's thermometer ensures that the inside and engine temperature of your vehicle is near the recommended set-point. This function prevents the engine from overheating or you freezing inside your car when the coolant level is not regulated properly. There are many types of thermometers used in cars; some are located at the dashboard, while others are outside the car or near the radiator. If you notice your engine's temperature spiking up while stuck in traffic, the immediate action you must do is replace your radiator thermometer-called a thermostat-before overheating takes place.
Difficulty level: Easy
Things you'll need:
- New radiator thermometer (one particular to your car's model and year)
- Gasket and gasket sealant (one particular to your car's model and year)
- Wrench set and socket set
- Flat-tip screwdriver
- Scraper or putty knife
Step 1: Open your hood. Twist the radiator cap slowly and let the pressure escape little by little. You may need a towel over the radiator cap for this. Also, prepare a bucket for catching some fluid that may escape from the radiator (put the fluid back after the replacement). Locate the upper radiator hose and remove it by unscrewing the clamps.
Step 2: Look for the thermostat housing. This is where the radiator hose joins the engine. Using the wrench, remove the two bolts that hold the housing.
Step 3: Remove the old gasket by scraping it off with the putty knife. Then, pull out the thermostat with your fingers, making sure that you remember its original position in order to make the installation of the new one easier.
Step 4: Place the new thermostat into the housing, spring-side down. Make sure that the top of the thermostat is secured by the narrow recess on top of the housing.
Step 5: Smoothen the surface where the gasket is placed. Sand away any remaining gasket traces. Spread the gasket on the thermostat cover. Make sure that the application is smooth and clean or the coolant will leak out of the cover.
Step 6: Replace the housing assembly, making sure that the bolt slots line up. Replace the thermostat cover, secure the thermostat assembly and the gasket with the bolts, and replace the radiator hose and cap.
Step 7: Pour the spilled fluid into the radiator fill hole or reservoir. Warning: Do not let the fluid spill on the ground; wipe it off thoroughly before hosing down the area to prevent endangering anyone.
Step 8: Let the gasket sealant dry completely before starting the engine. Check the coolant level, check for leaks, and make adjustments as needed.
