i just put in a new radiator and now temperature gauge reads high but their are no leaks
any make after 1997 will be susceptible to electrical issues when engine is normal. i wish they would have left the computer stuff out of vehicles. gauge is most likely electrically impaired.
1996 prelude temperature gauge reads low temp
The temperature gauge in a Pontiac Sunfire with a 2.2L engine typically indicates the engine coolant temperature. It should read within the normal operating range when the engine is warm, usually between 180°F and 220°F (82°C to 104°C). If the gauge reads too low, it may indicate a thermostat issue, while a reading in the red zone suggests overheating. Always refer to the vehicle's manual for specific details regarding the gauge and normal operating conditions.
If the engine is not overheating and the temp gauge reads normal, the thermostat is doing its job. If the engine is overheating, the thermostat may be stuck and in need of replacement.
Low Coolant or faulty gauge
The thermometer that reads your engine temperature, I presume, is damaged or broken. Without the gauge to tell your fan how hot your engine is it will keep running as a 'better be safe then sorry' feature.
Either your engine coolant temperature is HIGH , your oil pressure is LOW , or your fuel gauge reads at or near empty
your coolant level could be low
Oil pressure has to built up. As long as the pressure is normal and the oil level is good. There is no problem.
If the temp gauge reads normal and the engine is not overheating, this is normal. The system is designed to hold 15-17 psi of pressure (whatever the radiator cap is set for). This pressure will make the hoses feel hard.
I had this happen on my 2003 Sequoia while under warranty. I was a defective gauge and required replacement. Type your answer here...
Take wire off temperature sender look a guage. If guage at cool, temp sender needs replacement. If guage still at hot, temp sender wire shorted to engine or vehicle body.
