make sure your system is holding the required presure; usually between 14-19 psi, which helps your engine to run at a higher temp, therefore better efficiency. Loss of presure will cause your coolant to boil and steam away causing a shortage of coolant. this is either caused by a cracked head , a partually blown head gasket,
or a warped head from previous overheating
A properly sealed and presurized cooling system will make your engine run smoother and more efficiently, reduce wear and tear,
amd provide you with less overheating problems NEVER remove
your t-stat completely thinking it will make your engine run without overheatingl. T-stat only can raise your engine to rated temps, not
cause overheating. Unless, of course , its not opening at all or only partially. Test it in a pan of boiling water, if it opens fully, put it back in . Then look elsewhere for your problem ; radiator, fans, coolant flow blockage, etc. Good luck
