What sysrems will you see on your 97 ford ranger when the thermostat has gone bad?
If your engine thermostat sticks open it will run cooler on your temperature gauge and you won't see the temperature gauge go up to the point where your engine thermostat opens and then the temperature gauge will show a drop in temperature , your check engine light will probably come on , your gas mileage will be less , the heat from your heater probably won't get as hot If the engine thermostat were to stick in the closed position your engine will overheat ( but there are several other causes for an engine to overheat )
Why would 1998 mercury villager temperature gauge drop to zero with car in motion?
Low coolant level which causes an air pocket in the engine.
Why does temperature gauge go down if heat is on?
If this is about a car: the heater in a car is basically another radiator, but this one sitting inside the car. When you turn the heater on you draw heat from the engine and into the car. If you aren't running the car hard enough the temperature in the engine will drop.
Why does your engine temperature increase and then drop?
check fluid levels
Why would the temperature gauge drop when the heater is truned on?
The heater core is just like having another radiator, only smaller. Once you turn your heat on, and force air through the heater core with the blower motor, the engine's coolant's temperature is lowered, and circulated back to the engine, probably right where the temperature sensor is located.
Why does temp gauge on a 1998 sunfire drop when fan comes on?
because the fan cools the engine...
Your temperature gauge fluctuates when you turn the heater on?
Temperature gauge may drop when heater turned on because additional coolant from heater core is introduced to cooling system - usually this coolant is cooler than what is currently circulating
What would cause the check engine light to come on in 2001 Impala and the temperature gauge to drop to cold and then not work?
Could be lots of things. You should have it checked for codes. The temp gauge problem would make me think of a possible temp sensor problem. It should be located near the thermostat housing.
What would cause car temperature to rise when stopped but drop when moving or when engine is revved?
The thermostat is failing.
What causes oil pressure drop when engine has heated up during drive?
The oil gets thinner. It is normal for the oil pressure to drop after the engine has reached full operating temperature. If you have from 30-40 psi pressure when the engine is hot then that is normal.
What is the standard operating temp at idle on a 91 Chevy lumina is it normal for it to get to 220 before the cooling fans kick on or should the temp gauge never go past halfway?
First of all, the temperature gauges are usually way out of calibration because automobile gauges are made so cheap. You're looking for the trend of what the gauge indicates, rather than believing the indicated temperature displayed is correct. The normal operating temperature is 195 degrees F. On the gauge, you will initially see the temperature raise above normal, followed by a drop in temperature as the thermostat opens. It would be a good idea to place a drop of touch up paint or stick-on dot at the usual indicated temperature to have as a base line indication.
Does the temperature rise or drop in the thermospere?
drop
