What else can I help you with?
What could cause an intermittent overheat reading on the dash temperature gauge if coolant temperature sensor and the thermostat are new and the water pump and radiator appear to be fine?
Head gasket. Do block test for gases in coolant
Why does the needle on the coolant temperature gauge of a 1995 Saturn SL stay on the C?
The guage on the dash uses the ONE wire sensor... This is located in the block near the drivers side. Eric First check to see if you have coolant in the radiator. If there is no coolant you will not get any reading from the temperature sensor. If there is coolant then change the temperature sensor.
2000 Ford Escort ZX2 temperature gauge gets no reading Replaced temperature sensor radiator full of coolant Any Ideas?
Be careful there is a temperature coolant switch mounted next to the thermostat housing. I thought this was the sensor and replaced it by mistake. There is another sensor.
What causes your temp gauge to go to max reading when sitting still 04 dodge durango?
Overheating due to low coolant, inoperative fan, restricted radiator, etc.Overheating due to low coolant, inoperative fan, restricted radiator, etc.
Why does your temp gauge read almost hot when you have just replaced your thermostat serpentine belt and water pump and you have plenty of coolant in my 2000 ford escort zx2?
You may have a bad temperature sending unit. If that switch is defective, you will get a faulty reading. Also check the radiator to see if the coolant is flowing and there is no blockage in the radiator itself. Also check the belt for tightness.
What is the normal coolant temperature in a Cadillac?
Depending on the engine, the coolant temperature in a Cadillac could be from 180 to 195 degrees. The thermostat can be changed to give a lower or higher temp reading.
Why would the temperature on a 1993 Plymouth Voyager 30 go up when parking and not when driving?
Because when your moving, air is moving at the radiator, cooling it down, thus cooling your coolant down, thus cooling your motor temperature down causing the coolant temperature sensor to pick up a lower reading and relaying it to the gauge. Depending on how high it is in "Park" you may have poor circulation, a broken or missing fan shroud, weak water pump impellers, low coolant, inactive coolant fans or a bad fan clutch.
1947 Mercury with a 460 engine It runs hot no obstruction to the radiator The temperature runs up 210 to 215 it has electric fan- radiator fan was designed for this engine.has not bowled over?
My question is, where is the engine coolant temperature sensor located, in a cylinder head or in the intake manifold close to the thermostat? If it is in a cylinder head it will give you a hotter reading than if it was in the intake manifold.
Plymouth sundance temp gauge is reading hot?
If your Plymouth Sundance's temperature gauge is reading hot, it could indicate that the engine is overheating. Check the coolant level in the radiator and reservoir; low coolant can lead to overheating. Additionally, inspect for leaks, a malfunctioning thermostat, or a faulty water pump. If the issue persists, it's best to have the vehicle checked by a mechanic to prevent potential engine damage.
Where can you put a temp sensor on a 283 other than the thermostat housing?
You can install a temperature sensor on a 283 engine at the intake manifold, specifically near the water jacket, which can provide an accurate reading of coolant temperature. Another option is to place it in one of the cylinder head's water jacket plugs, if there's an available port. Additionally, using an adapter fitting in the radiator hose can also be a viable location for monitoring coolant temperature.
How does the radiator fan of a 1992 Pontiac sunbird activate and deactivate?
The PCM (powertrain control unit/computer) sends power to the fan relay based on the output of the coolant temperature sensor reading. The relay then sends power to the fan; thus turning the fan on.
Why would the temperature gauge read cold when the antifreeze is low?
The temperature sender (the sensor that sends the temperature signal to the gauge) has to be immersed in coolant in order to correctly read the temperature. If the coolant is so low that it leaves the sender high and dry, the temperature shown on the gauge will not be a true reading. if the sensor is not immersed in the coolant, there a big chance it wont read at all...
