Why does the engine temperature rise when the car idles?
Engine temperature rising when the engine is idling is normal. The car is sitting still and no air is entering the engine compartment. This will cause the engine temperature to rise. The cooling fans then come on and the engine returns to a normal temperature. Unless the cooling fans do not bring the temperature down, you have no problems and this is totally normal.
Why is the top radiator hose hotter than the lower Is it normal for the top hose to be two to three times hotter?
The coolant comes from the engine at it's hottest through the top radiator hose, cooling as it goes lower and lower in the radiator until it comes out the bottom radiator hose at it's coolest temperature and back into the engine.
Why is there pressure in the radiator?
Pressurizing the cooling system raises the boiling point of the engine coolant. under normal conditions this keeps the coolant from boiling and having to be frequently topped off.
How do you change a thermostat on a 1998 Saturn sw?
Probably located at engine end of upper radiator hose in removable housing. Drain about 1 gallon of coolant from radiator Remove housing Note how thermostat is installed in housing Clean both surfaces Install new thermostat and gasket Re-fill cooling system slowly to prevent an "air lock" Start engine and look for leaks Run engine to normal operating temperature with heater on Check coolant level
What can cause high pressure in the cooling system of a Saturn?
High pressure in a car's cooling system might be caused by exhaust gases from normal engine combustion entering the cooling system. The exhaust gases might be entering the coolant due to a head gasket that is leaking, or perhaps even due to a cracked engine block. Note that under normal operation, cooling systems are pressurized due to the heat expansion of the coolant. However, if a fairly new radiator and/or hose has burst, or if the coolant hoses connecting to the radiator are rigid with pressure, this is abnormally high pressure.
You have an 88 IROC with a 5.7 you just had all the cooling hoses changed radiator flushed new coolant and a new t'stat installed at idle the car gets up to 240 degrees is this normal?
install aftermarket gauge
How do you install a thermostat in a 1992 escort gt?
Drain about 1 gallon of coolant from radiator Follow upper radiator hose to engine Disconnect housing Note how thermostat is installed Clean both surfaces Replace thermostat and gasket Re-fill coolant slowly to prevent "airlock" Start engine-look for leaks Run engine to normal operating temperature with heater on Check coolant level Drain about 1 gallon of coolant from radiator Follow upper radiator hose to engine Disconnect housing Note how thermostat is installed Clean both surfaces Replace thermostat and gasket Re-fill coolant slowly to prevent "airlock" Start engine-look for leaks Run engine to normal operating temperature with heater on Check coolant level
What would cause the cooling fan to only work when the air conditioning is on?
The Cooling Fans ( 1 Small & the a bit Larger ). The Big One Is For Cooling The Radiator For Normal Engine Usage. When The A/C Is On The Smaller Fan Will Run To Allow More Air To Be Pulled Over The Condensor And Radiator, To Better Cool The Water & Make The A/C More Efficent. There Is A Sensor In The Engine That Controls The Cooling Fan This May Have Gone Bad. I Would Begin My Testing Here First. Then Test The Fan To See If It Is OK. Hope This Helps
When driving my 06 ford explorer the engine make a loud fan blowing noise?
The cooling fan is coming on cooling the engine. Very normal.
Why is there pressure in the upper radiator hose?
The pressure in the upper radiator hose is created by the water pump circulating coolant through the engine and radiator. This pressure helps to maintain proper flow of coolant to regulate engine temperature and prevent overheating. It also allows the coolant to absorb heat efficiently from the engine.
Why is the radiator fan still running after turning it off in Honda acored 94?
The fan will run anytime the A/C or defroster is on. It may also run after you shut the engine down if the engine is running hotter than normal. I would have the cooling system serviced.
Where is the radiator fan switch on a 2001 Camry?
open your hood, locate the radiator, its on the left hand side at the bottom of the radiator, its pupose is to close the circuit when the coolant get above normal and turn on the cooling fans.
