Yes that is cool if it's correct. 195 F is approx.as low as you should have. I'd change it. Be sure to run with cap off, and heater on (not defrost) while refilling system. Wait for rad fan to come on 2 or 3 times before you put cap back on, then add coolant to return bottle as needed. Make sure rad fan only comes on when up to normal running temperature. If it runs all the time, it may be causing low coolant temperature too.

1996 jeep cherokee temp gauge reads hot 10 mins. after start-up


If you have a viscous fan hub then have it replaced as it is not drawing air through the radiator at idle or slow speed (crawling traffic). Check that are no air locks in the system as they will cause heating problems.

2005 Dodge Caravan, temp gauge has been rising to "hot" while driving. Just recently, van lurched while driving 30mph and then the check engine light came on right after. Temp gauge was normal...


I would guess that the lurch and the engine light on was telling you that the engine over heated and you may have done damage to the motor.. IF you have blown a hose or radiator or lost a lot of water then the temp gauge sender has no coolant to read so it will read as normal. because it is reading an over heated piece of metal that it is screwed into and not the coolant temperature.. Have a compression test done to determine possible engine damage. Have a pressure test done on the coolant system to find the cause of the loss of coolant. Do a flow test done on the radiator to check for blocked cores. Check operation of cooling fan especially if you have a viscous fan hub.

My 2000 Montana gauge is showing that's over heating even when it's driven a short distance and when driven on the freeway it's not smelling like its over heating or there no steam coming


If the gas gauge does not work correctly and the temp gauge reads hot, you could have a problem with the instrument panel.
Both gauges get power from the same circuit, but each gauge is grounded by its own sending unit.
If the temp gauge is reading correctly, you could have air in the cooling system and it is not actually full of liquid coolant.

2004 Suzuki Forenza-changed antifreeze-now overheats-if I turn to the right temp gauge drops back to normal.


Did you bleed the air from the system? That must be done or the system developed air blocks and this causes it to run hot.

Is there any way to get heat faster in the morning? Even if I start the car and run it for a few minutes, I have to drive it a few miles to get any heat out of it.


have the thermostat checked and make sure the heater core is flowing. it may have a problem, or just be normal? is the temp gauge reading normal temp, or colder than it used too.

Car temp gauge/heat


TDIs can take a while to heat up in cold weather. Sometime 10 minutes or more.

If it is taking longer than 10 mins for your temp gauge to hit 190, you may need a new temp sensor, which is pretty cheap and just pops into the engine block, almost right next to the battery.

Possible overheating, 2004 pontiac montana


Its definitly a bad reading, you would know if your vehicle is overheating, you can usually smell it right away.I would say its your temperature gauge sending unit is defective, check the wires to see if they are well connected or broken. ask a backyard mechanic for assistance.
