I have 2000 camery.My mechanic changed Timing belt Water pump Head gasket Temp. corol temp esnser and changed cylender head. still I have the same problem Spend lot of money Is there any simp

Get your money back like time now. You've been screwed. Overheating right? I see he changed cyl head. Did he machine the block too? Get your money back. That's b.s. 3500? Thats skull cracking $. If he didn't want to give you your money back, take a cap full of bleach to his gas tank. That should fix his ass. He's gonna spend a lot more the second he cranks it. Or, do like me and crack that skull. Dunno about you, but thats 3500 in food off my table for my family. Better get down.

Overheating causes: 1) Lack of water/antifreeze 2) Thermostat 3) Water pump 4) Leaks 5) Heads being either warped or cracked 6) Head gasket Ya know, the fact that he changed out the cylinder heads leads me to believe the heads were toast. However the heads sit on top of the block. Whole motor runs hot. Not just the heads. Your block might be warped and or cracked. If warped and when replacing heads you have to machine the block if it is just micros off. Dunno if the car is worth it as you could have gotten a replacement in the same year and model poss younger for the money you have dumped into that one. Good luck man.

If we assume all the work was done correctly....I suggest you check coolant flow through the radiator. With the engine cold...start her up and put one of your hands in the top radiator hose....and your other hand on the lower radiator hose.....then wait. When you feel the top hose getting warm...that means the thermostat has opened. Shortly after the bottom radiator hose should start getting warm. Eventually...after about 5 min. both hoses should be hot....but....the top hose should always hotter than the bottom hose....and eventually the coolant fan will turn on. BE CAREFULL...don't get caught in the rotating parts of the engine and fan. Good Luck
