I need help everytime i turn on the car for about 10-15 minutes my engine temp gauge goes all the way up. I dont know if this is normal but everytime i turn on a/c the fan turns on. Well anyways could it be thermostat since my car was sitting in garage for about 8 months.

check the antifreeze. you might have a radiator leak.

check your coolant, then thermostat, and also look for anything leaking from your raddd

I checked my coolant and radiator for leaks everything good i replaced the termostat and its still overheating could it be a water pump?

try a few more things first.

start the car, leave the radiator cap off. i did this once just for fun and coolant somehow didn't spill out. i could see the thermostat opening and closing with coolant going by. try that and see if things look kosher.

if it doesn't work, then i guess your water pump could be having issues. when was the last time it was replaced? if it needs replacing, you might as well do the whole timing belt procedure.

ok u said ur ac fan is coming on but what about the other. Start it up and let it sit there and check if ur fan is coming on when ur car gets hot.
