Yes, coolant level is fine! The temp. gauge goes to red hot or pinned as soon as I start the car cold. And…after approx. 15 min. driving locally, the engine doesn’t seem to be overheated. so I’m assuming that the thermostat is working fine. I’m just afraid to drive it longer or farther when the temp. gauge says red hot.

Why is the temperature gauge pinned hot on my Honda?

Cut repair costs, not quality. Since you are experiencing no overheating problems the most likely cause is that the engine coolant temperature sending unit is faulty. This sends a signal directly to the dashboard gauge. There is another coolant temperature sensor close by which sends a signal to the ECU to help in engine management.

How is the power of a water heater determined?

Residential water heaters use varying amounts of power depending on the size of their heating elements. The power amount is given in watts for the heater, and the wire gauge size is dependent on the amps drawn by the heater. Divide watts by voltage to find amps.

What should the suction pressure be on a hot water heater?

A 12-psi setting will lift water 28′ above the fill valve. A 15-psi setting will lift the water to 34′. At 12-psi, the boiling point at the fill valve/gauge is 246 F. At 28′, it is 212 F. If the level of the water isn’t high enough because there isn’t enough fill pressure, the suction pressure on the loop may cause…

What does it mean when your temperature gauge is not working?

The temperature sensor/sending unit is faulty. If this is the case your sensor will be reading the coolant temperature incorrectly and sending the wrong signal to the gauge. This could work in either direction and read as cool when it’s running hot or hot when it’s running cool. A malfunctioning circuit in the temperature gauge

What to do if your coolant gauge is not working?

Run the engine for about 20 minutes to get it up to temperature or until the gauge says you’re running hot. Open the hood and take a look at your coolant tank. Most tanks should have two lines marked on them, the top one reading as “full/hot” or something very much like that. Your coolant should be at that line after 20 minutes of running.

Why does my car temperature gauge go up and down?

If the Temperature Gauge Goes Up and Down You may notice that your temperature gauge reading goes up and down, fluctuates in some kind of pattern, or is erratic. There may be several reasons for this: Low coolant level delaying thermostat opening and closing (check coolant level in the radiator).

How can I tell if my light gauge is hot?

Check the gauge if the needle moves toward “Hot”, the wire from the gauge to the sending unit has an open or bad connection. If it does not move, connect a test light by grounding one end to a good known ground and the other end to positive side of the gauge (typically a pink wire).

Why does the temperature gauge on my car read Cold?

If the temperature gauge still reads cold after the engine has warmed up, the gauge may simply be broken. Another reason the temperature gauge could read cold is if the thermostat in the vehicle stays open.

What should the voltage be on the gas gauge?

Remove the fuel pump module so you can manipulate the float arm. At this point, with the key in the ON position (but without starting the engine), back-probe the connector and check for voltage. You should always have 5 V or 12 V on one of the pins. One of the other pins will be voltage feedback to the gas gauge.

What should I do if my gauges are not working?

The first step in diagnosing this type of issue is to identify the fuse associated with the instrument cluster or gauges. The fuse should have power on both sides when the ignition key is turned to the on position.

Why does the Volt gauge go up and down?

The voltage always fluctuates, goes up and down depending on how much current is being used by the accessories, and the engine rpm, the charge state of the battery, the ambient temperate, all affect the voltage. Fluctuation is normal, it’s like the stock market.

When to troubleshoot an unusual voltage system drop?

Troubleshooting for Unusual Voltage System Drops Usually, the first sign that your charging system is in trouble is a “battery,” “ALT,” or “CHARGE” warning light illuminating on your instrument panel while driving. It means that for some reason, the alternator has stopped charging the battery and your car is running on battery power.

What does a 5 Volt voltage drop mean?

But, before you condemn it, run a voltage drop test between the alternator and battery. GM typically runs a fusible link wire between them for overload protection and they can go bad, mimicking a bad alternator. A voltage drop of .25 volts or less is Ok and the alternator is bad. A voltage drop of .5 volts or more means the wire is bad.

How does a voltage drop test work on a car?

A voltage drop test will assess voltage losses at the battery, the alternator and the starter. 1) With the voltmeter connected to battery, and key and engine off, record a “base” voltage reading. (Your battery should have a minimum of 12.4 volts.)

Is it normal for the temp gauge to go past half way?

Diesels do run slightly colder, but around half is fairly standard on every car I’ve owned. The gauge doesn’t have useful information, that’s why a lot of cars don’t even bother putting temperature range on them.
