When it comes to engine tempetures 180 degrees is when the thermostat =should open allowing good circulation to cool the engine. now at a 50/50 ratio of water to glycol coolant the engine can run as hot as 240 degrees before it reaches the boiling point and causing damage. now most gauges in vehicles read 190-210 degrees when the needle is at the top center. nothing to realy be alarmed about. However if your engine is steaming over then that is something to beconcerned about. also if you have a bad temp sensor your not going to get an acurate reading. if the wires are broken or the plug is bad then you won't get a good reading either. in higway use the airflows over the radiator at a higher rate so the needle should drop if it doesn't then just check the connection to the temp sensor if they are good then just replace the sensor because it' faulty. please rate this....thanks
What is the spacific temp for this car threw the factorys specs. check those and if it is still running hot you need to check your fans and just to be safe replace your water pump. i know it cost but still it could fix the problem. if that dont work check the thermostat they can stick open and or closed. you may also need to have your oil and filter changed. DONT USE PENNZOIL it is hard on a motor after long term use.
