Could my temp gage gone bad or the thermostat

Asked by May 25, 2018 at 07:45 AM about the 2015 Nissan Altima

Question type: Maintenance & Repair

Okay I’m currently have a 2015 Nissan Altima s 4 cylinder
, about last September she got in to an accident taking
out the radiator, core support, fan assembly, condenser w,
etc , however there where was no other major damage to
engine or anything like that . We replaced all that and now
she not leak or anything coolant seems to stay about
same level , however my temperature gage is hitting hot in
the matter of minutes , especially if taking highway , when
pulling over letting cool down and just basic check
everything seems fine (no smoke ) and doesn’t feel hotter
then normal temp , I’m just wondering if this could be a
faulty sensor or a thermostat , seeing how we didn’t
check those in the process of fixing everything . Any
thoughts or ideas of what to check ? And is it okay to
continue driving until I can get if fixed tomorrow

it could be the fan control relay, the cooling fan temp switch, the water temp sensor, engine coolant thermostat, or the engine coolant water pump. My bet would be the engine coolant pump isnt working, or the coolant thermostat is bad. Is the radiator fan working? Also id be very careful driving the vehicle if you dont have another choice. If it gets too hot you could blow the head gasket, warp the cylinder heads and other things which will cost you a fortune to fix. Just make sure you allow the engine to cool down before driving again and when it starts to overheat dont let it get too hot.
