Does it over heat within 5-10 minutes. If so (Thermo stat.)
At idle if its over heating, but staying cool while driving ( water pump, 0r fans not comming on)
If ur driving it and its throwing all the antifreeze into the resevoir but not pulling it back into the radiator ( radiator cap)
Change your oil, if u change it and it looks milky ( headgasket.)
When the car is cold, take the rad cap off and crank it. Watch for alot of white sweet smelling exhaust coming outhe tail pipe and also for bubbles in the radiator itself. If this is happening probably ( headgasket )
Make sure none of your fuses are blown as well. Make aure your cat isnt clogged even tho new ya never know.
Let us know whats up.
