This could happen if your fan is indeed weak.  To test disconnect the thermostat of the radiator by removing the terminals near the radiator hose towards the engine.  You should see the fan run at its highest speed, then you can check if your fan has weakened.

Look for a loose connection to the temperature sender unit on the motor.
If all connections OK, you may need a new temp sender unit.

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.

Overheating when I sit idle.


Over heating the engine is a serious concern. With the hood raised you should hear the motorized fan turn on just behind the radiator as the engine requires additional cooling.. If you look in from the rear of the radiator you should see the fan blades.

This electric powered motor operates on a thermostat and when the engine temperature rises this fan should come on. I'm assuming from your description that when driving and air is flowing through the radiator as the car travels the engine is nor overheating.

Check fan motor thermostat, check fan motor and check wiring.

I have a 2003 Honda Civic, I notice that it only takes a few seconds for my vehicle to warm up to normal. I can drive my vehicle for approximately 30 miles before I can see that it starts to over heat,...


Usually caused by a blown head gasket. Open the radiator cap and start the engine. Make sure the system is full of coolant and keep it full as the engine warms up. Once it's warm and the thermostat is open, allow a couple minutes for any air to bleed out. If bubbles continue to come up the radiator, your head gasket is blown. If you aren't getting bubbles, the problem may be a clogged radiator. Look to see if the coolant is flowing in the radiator. If you have more questions, please let us know.

The temperature of my 1993 honda civic it''s going up when i am driving it what could the problem be


Typical issue with the 92'-95' Civic. Thermostat is one possibility, yes. Another is that it overheated due to the thermostat or the fact that they have a very small radiator which tends to corrode and become increasingly less efficient, in time causing it to everheat and eventually cracking lengthwise away from the radiator cap along the (plastic) top of the radiator due to steam pressure on the inside of the rad. Inspect the fins on the radiator to ensure they are not turning green and corroding away, this will make a marked difference in your colling capability.

Honda civic 2004 changed radiator,thermostat control,changed cylinder head with machine shop, new fan...still temp rises beyond half..mechanic told me to fix engine block and machine shop again cylinder...


the gauge is going above half, but is it actually over heating? could be a faulty coolant temp sensor sending an incorrect temperature. when you changed the radiator, was the rad cap also changed? if the cap is not holding correct pressure, it will lower the boiling temp of the coolant and cause it to overheat. an infra red thermometer is very useful for diagnosing this, point it at the thermostat housing and see what the temp is there, that will tell you whether the temp gauge is accurate or not. good luck!
