This may be the service engine soon light which shows that you just went from closed loop to a limp mode open loop.

Changed out water pump and thermostat and vehicle runs high temperature what could be issue?


Reasons the Temperature Gauge Reads High

If the temperature gauge reads high, it could mean your engine is overheating. Another reason your reading might be high is you could be losing coolant. A small leak or evaporation may cause your radiator to slowly lose coolant. A third reason your temperature gauge reads high could be because the thermostat is broken. If this is the case, you may need a coolant temperature switch replacement. The last reason the temperature gauge could read high is because of a water pump, or water pump gasket failure. If the water pump is malfunctioning, it may need to be replaced by a professional.

What to Do If Your Temperature Gauge is High

If your temperature gauge is reading high, it means your car is overheating. This is a very serious matter and you should never drive an overheating car. If your car starts to overheat, shut off the air conditioner and open the windows immediately. If this does not reduce the overheating, turn on the heater as high as it can go. If this still doesn't work, pull over on the side of the road, turn off the engine, open the hood carefully, and wait until the vehicle cools down. Never open the radiator cap while the engine is hot - coolant can spray and burn you. Once the vehicle has cooled, take the car to a mechanic right away so they can diagnose the problem. Cars are especially susceptible to overheating in hot climates, like what's common in cities like Los Angeles, Phoenix, Las Vegas, or Atlanta.
The temperature gauge is an important tool in your vehicle that shows the temperature of your engine's coolant. Contact YourMechanic and have your car inspected for overheating if it reads too high, as this can cause serious problems...

Reasons the Temperature Gauge Reads Cold

On most vehicles, the temperature gauge reads cold until the engine has run for a few minutes. 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. With the thermostat stuck open, the engine can be overcooled, causing a low temperature reading. If this is the case, the thermostat may need to be replaced.

The seller drove the car without knowing both engine fans were off we opened the hood the car was very hot she said it's never overheated on her and the temp gauge was halfway


The fans are normally thermostatic - which means they only operate above a certain air temperature. If the air coming across the radiator is below a pre-determined temperature, they will not operate.
If the temperature gauge was only half way they may not have reached the required temperature to turn on.
When you are travelling the movement of the car usually provides enough air across the radiator to keep it cool enough - when you stop and they is no moving air, the fans will normally come on then.

Hi i have a volkswagon golf which the abs sensor light is on and another yellow light is on in the dash and sometimes it beeps and the red handbrake light will flash. also my speed clock doesnt work at any...


firstly you need a new sensor or drive on the gearbox ,its located above the passenger side drive shaft where the diff is ,change this first so it works then see if the ABS light goes out ,temperature gauge could just be a faulty sender unit on the engine .If the ABs light still doesnt go when speedo is repaired then check the sensors with a automotive meter and also check the toothed gear ring on each wheel as they do sometimes crack and come loose on the drive shaft .This fault will also throw the brake warning lights on for this vehcle

I have a 1983 Chevy S10 pickup. With headlights off all gauges work normal. When you pull the headlight switch on all the panel lights except the windshield wiper switch locator light never turn on and all...


take a look at the dash ground wire located next to the right of ebrake release handle. if the bole holding the ground wire is loose, which was quite common it will cause all kinds of feed back problems, like described in the comments section to your question.

My temperature gauge is not registering and my check gauges light comes on when im at a stoplight.when im driving the oil pressure is fine but when i come to a stop or idle the check gauges light blinks on...


A faulty temperature sending unit. It should be located on or near the thermostat housing. If any of your gauges reads zero, the check gauges light will come on. Sometimes even if the fuel gauge gets too low, it will trigger the light. It may be the connection at the sending unit. It may have become loose so wiggle it and make sure it is securely connected to the sending unit. If the temp. gauge needle pegs at the top of the gauge, it means the sending unit has grounded out and is faulty. If it jumps, reads off or not at all it could be a faulty sender or a bad connection.

With a 2001 oldsmobile alero the temperature gauge shuts off , service engine light goes on but heat is still working, what's the problem


If by "shuts off" you mean goes all the way to the cold or no temp, then sounds like the thermostat is open and needs to be replaced. Could also be the temperature sensor and you are losing the signal. I would check to see the actual temperature of the engine to know the difference.
