it may be your thermostat or water pump is it over heating with steam comming out ?
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.
i just put in a new radiator and now temperature gauge reads high but their are no leaks
In all probability you either have a bad radiator cap or an air lock.
If the engine is cool or cold, this is normal. If the engine is normal operating temperature, then possibly the thermostat is jammed/stuck, an air lock maybe or a blown head gasket. You may have a faulty radiator cap also or the coolant could be too low.
With engine cool - remove radiator cap Run engine to normal operating temperature and try to observe coolant flow inside radiator - should be little to no flow until thermostat opens and then full circulation should be observed.
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.
A minor increase is normal - however if excessive check:Cooling fan working?Radiator clogged or plugged?Air flow to radiator restricted?Bad radiator cap?
160 TO 180 degrees. should be the norm 1928/29 will run hotter that the 30/31 due to radiator size .30/31 radiator is larger
Run engine to normal operating temperature witout radiator cap Observe coolant circulation If coolant blows out of radiator - could be a stuck thermostat If no circulation could be a bad water pump
On my 4.0 L OHV engine the top rad hose gets hot when the thermostat opens , and the bottom hose from the radiator returning to the water pump is much cooler because of the heat given off by the air movement through the radiator reducing the temperature of your coolant. Once your engine is warmed up , as long as your temperature gauge works and displays that the engine temperature is in the normal operating range , that's normal.
the normal operating temperature for cars is around 190 degrees.
160 to 185 degrees F is normal running temperature.
