My 1999 Chevy venture has been running horibly. We have replaced the relay switch to the fan motor, water pump, radiator, intake gasket and the thermostat and gave the car a tune up. It is still running hot and guzzling antifreeze and the fans still does not come on all the time. The car is hissing when I shut it off and we have thourghly inspected for leaks. We have also replaced one hose. There is no antifreeze on the ground or on the motor anywhere. Any suggestions?
SOURCE: Overheating
Make sure you don't have a bad head-gasket. Check for excessive pressure in radiator or hoses. Check under oil cap for creamy/milk like residue or actual antifreeze in oil or the opposite oil in antifreeze. Let me know what you find. Good Luck

either the temp sensor is bad but, it sounds like the fan relay is stuck.
replace the relay its in the fuse box.

you need to change the clutch fan and flush the radiator.
SOURCE: 2000 chevy lumina. Is fan supposed to come on when car started
no fan comes on when engine cold start up .but it will come on when you turn on air conditioning or defrost on .if engine idling a while when temp get 190 degree the fan will kick on.if over heating you got air in system .wait until cools check coolant add more .crank engine let it idle few. minutes when start warming up turn off engine wait a while before removing radiator cap so you wont get scald.add more coolant .crank it again starting warming up turn off engine wait a while .add coolant .keep doing this procedure until your coolant stop dropping off .if you do this more than 6 times you got a leak some where.check crank level for signs.if oil level higher than normal.if everything looking good.when engine cool make sure add coolant to over flow jug cold level mark.

it could but- check passenger side front where heater core line go into manifold right behind alternator the hose line is connected by a press clip into an alloy fitting this fitting gets eaten away by anti freeze and hose angle pulls back on fitting the part is $18 at dealer and is screwed into manifold use caution if ur r going to replace at very edge of aluminum manifold---and check ur water pump bolts the 2 longer ones should have a lock sealant on them they bolt in thru a water jacket
