this is a early model pontaic the temp sender is in the intake . the temp of the water in the radiator would have to be at least close to what the gauge says right ? so my gauge is wrong right?

The water in the radiator is cooler than the water in the engine. Perhaps you have a bad thermostat. Or it could be that the temp. sending unit is bad. Or the Gauge. These suggestions are if the engine is not getting hot or boiling over.
It is more than likely the sending unit.

Bill is the only one that got the right answer, except me. But you can tell by pulling the thermostat and seeing what temp is on it. When the engine is fully warmed up. The thermostat opens allowing coolant to leave the radiator and enter the engine. Thus maintaining the temperature that is on the thermostat. At least that's the idea. You cannot pull the radiator cap and expect the same temp. Water boils at 212F, by pressurizing the system you can get 8 more degrees in temperature (220-212) before the coolant reaches boiling temp, at which time a vent in the radiator cap opens, maintaining that pressure. My guess is you have a 220 degree thermostat and your Gage is correct. You experiencing overheating? Could be a lot of things, bad thermostat, radiator cap, make sure the electric fan is turning on, bad head gasket. Good luck.

They both are. The gauge is reading the water temp. inside the engine. The thermometer you used is reading temp. in radiator which should be lower than in the engine anyways, if it isn't then the system isn't doing it's job right and needs to be looked into.

no theyre both right. your gauge works like a fuel gauge in this case the 220 mark if your needle should reach it. you are running extremely hot. if you put a thermometer in the water and it read 160 then your thermostat is doing what it is suppose to do.

Liquid will get hotter when under pressure. In order to put a thermometer in your radiator, you do not have the system under pressure, thus the temp will be lower. So, your gauge and your thermometer are probably right.

no, ur gauge is right, the temp of the radiator os AFTER it's been cooled. if they were the same the nwhat good is a radiator?

Well, what's the issue here? Who cares what the temperature reading with your thermometer is? Are you having issues with the car overheating? If not, just drive on.

Check the error values of both and
are u reading the same scales??
