Yes it is normal. Your average car operating temp is 210 to 220 before the thermostat opens. You can buy another thermostat that will kick in at 180 degrees. It only costs a little more and is better for your engine and transmission. I have always replaced my old ones with that and have had great results however in the winter the heater will not get as hot because the car is running cooler than before.
Depends. A normal cooling system runs between 195 degrees when the thermostat opens, to 230 degrees when the cooling fan kicks on. If you are experiencing air temps over 90 degrees, the cooling system could run at 210 or higher. Idling and moving make a difference too.
I would suspect either the temp guage or the coolant temperature sensor being inaccurate. The new thermostat is probably working good, or else you wouldn't have a very warm heater. If you have electric radiator fans, you might check to see if they are running all th time. Electric cooling fans should only come on when the temperature sensor reaches a predetermined coolant temp, or when the a/c or defroster is turned on. If the fan runs all the time, the engine would not reach normal operating temperature.
Thermostat checking: 1. Cold engine. Start up the engine and watch of the water temp indicator. After first value 140 degrees F you still warm up the engine until the lifter (pointer) reach 175 deg. F (second mark after 140 deg. F). At this time you let engine running at idle speed and check with your hand the thermostat plastic housing and hose temperature in bottom left side of the engine. Heed of alternator driving belt and ventilator fan !!! 2. If the thermostat is good the hose must be cold until the water temp indicator reach almost 195 deg. F. 3. The thermostat opening temperature is 188 deg. F. 4. If the hose is already warm the thermostat is out of order.
The temp reading on the dash is a very big clue... Likely the thermostat (at the end of the large top radiator hose inside the metal housing) is stuck open. When that happens, the coolant in the engine never reaches full temp. Not only can that result in a low heat condition but it can also give you poor fuel mileage as the computer always thinks the engine is cold and therefore it adds extra fuel to keep it running. Replace with a 195 degree(f) thermostat, run the engine (with the heater on full heat) to nearly normal temp, turn it off and wait about three minutes, then re-start and continue filling. Once full, add whatever is necessary to the recovery bottle and close it up and check for leaks.
completely normal those readings are perfect this car comes with a 195 degree thermostat,210 is fine for stop a go traffic remember a cooling system with the proper amount of coolant in it and under pressure will not overheat till about 240 degrees your in great shape no conerns!!!!!...
The cooling fans on this vehicle won't come on unless the a/c is on or until the engine coolant temperature reaches about 220 degrees. Once the coolant has reached this temperature the fans will come and and run until the engine cools down to about 210 degrees and they will then turn off until the temperature climbs up again. The fans usually aren't on at all at highway speeds because enough air is being forced through the radiator to keep everything cool. The true test of cooling fan operation is to allow the car to idle in park with both the a/c and defrost turned off and let it run until the fans come on. When The temp gauge reaches about 3/4 of the way up, give or take a bit, the fans should come on. Keep an eye on the gauge so the engine doesn't overheat just in case there really is a fan control problem but I'd say you'll most likely find that the fans are working properly since they do come on for the a/c. Hope this helps!
You could have a crack in the flywheel/flexplate where the crank sensor reads. This crack can cause random misfires as it passes beneath the crank sensor but it is fairly rare and hard to find with the transmission bolted up. The cranks sensor is also prone to being damaged or not being properly spaced where it mounts above the flywheel. Do you know if there are any service codes other than for a random misfire which is usually a P0300? The cooling fans on these were designed to stay off until either the A/C was on [like yours is working now] or until the engine temp reaches about 220 - 228 degrees at which point the fan[s] would run until the engine temp drops back to about 210 or so and shut off again. At a true engine temp of 190 to 210 theu should stay off. The best fan test is to start the engine, leave the a/c and defrost off, and allow it to idle in your driveway until the gauge reaches about th 3/4 to 7/8ths of the way up and somewhere in there the fan should finally come on. If not then you need someone with a scan tool to command the computer to turn the fans on and off to see if it is capable of doing so but I'm betting it is since it will turn them on for the a/c. I have both a 94 and an 02 caravan and when I'm sitting in traffic they'll hang at the 210 - 228 degree point all day long [actual temp as read on a scan tool] which is ok because the cooling system is pressurized and the coolant can't boil over. Once I'm moving over 35 mph the temp willd drop back down the the thermostat set point which is about 198 degrees on both. Hope this helps a bit with your problem and good luck!
