Are you overheating? If so,you may have a radiator that is plugged and needs replaced. It may just be too old and is leaking still needing replaced.Third,if you have a head gasket blown,it can push the coolant out of the system.You would have to check the compression to find this problem,not a hard one to diagnose either.
Radiator fan could be bad, fan relay bad, fuse blown. Also if your ECT (engine coolant temperature) sensor is bad the ECM (computer) won't know to tell the fan to turn on.
Several solutions: Change the thermostat (could be sticking shut).....backflush your radiator....could be dirty and clogged, replace radiator hoses, check for pin hole leaks in your radiator. Is the fluid level staying normal or are you constantly adding anti-freeze? Halfway on the scale is normal.
It could be anything, but the most common problem is the O2 sensor.
Could be EGR valve sticking open or dirty at an idling condition or hesitates when accelerating.
first , the thermostat could be stuck. try replacing it. if your radiator OS losing coolant, there may be a leak in the radiator causing it to overheat, or the water pump could be bad. thermostat is the likely cause if it is not losing water.
There are a few reasons why a 1997 Toyota Camry may be losing power. A few of the reasons could be a bad battery, ignition coil, or the fuel pump.
Thermostat could be stuck shut. Or the water pump could be failing.
Check for extra white color in the exhaust,could be a ruptured head-gasket.
have you checked ur thermoswitch or the relay Simply check if the fan units are running when the engine is hot. Easiest to do when the hood is up. Are you losing coolant from the expansion tank, this could be a sign of failed Head Gasket.
There could be a number of reasons. Damage to the radiator, damage to the pipes and hoses linking to the radiator. Water pump failure. Head gasket failure.
Most of the time internal water leaks under the dash behind the center console are the result of a blown heater core. If your heater is not working, then that could be your problem.
I would say that you are losing coolant somewhere hoses,water pump,radiator.
