Thermostat could be sticking close check see if both radiator hoses hot to touch if no thermostat stuck close not allowing coolant pass from engine through the radiator.could have bad fan clutch.check water pump weep hole if you coolant leaking at water pump.it is more likely going bad locking up shaft bearing.check your engine oil on dip stick, if looks brown milkly head gasket leaking.

Hi... you are going to have to do some more checking. After the engine is cooled down open the radiator cap, look for goo on the bottom of the cap. Look for oil or goo in the coolant.

What you PROBABLY have is a bad head gasket and the pressure is pushing the coolant out of the engine...

I wish I had better news...

Why is my add coolant light on


your coolant light is on because there is not enough coolant in the radiator. When the coolant is hot it expands and the excess water is pushed out into the reservoir and as it cools down the water is sucked back in and so keeps the top tank of the radiator full. However if you have a leak or a faulty radiator cap the water comes out ok but instead of sucking back in water it allows air in instead. Therefore you have a one way circuit of water out but no water back in. Your coolant light is telling you to check out the fault before you over heat the engine

Coolant leak


On these mini vans there are lines to back if it has temp control in back. How much water do you loose in what period of time? If no leaks found then check exhaust while running to see if coolant smell from there. Could have leak in gasket on intake allowing water in or head gasket and just burning water. Has fuel milage dropped?

Hello my 1994 camry toyota has a problem holding the water. We replaced the thermostat,fan switch,radiator cap, and it keeps comsuming the water. What do you think the problem might be? Javier


Javier, have you checked the coolant overflow tank for holes, cracks, or loose hose? When the engine in your car heats up, the coolant expands. The coolant overflow tank (located near the radiator) takes up any coolant that is forced out of the radiator. If the tank is damaged or not connected to the radiator correctly, the coolant will not siphon back into the cooling system when the engine cools off.

Coolant light keeps coming on


It could be low on coolant,or air in the cooling system,or the coolant low sensor needs cleaning.

Why is all the fluid staying in reserve tank-none


The line to the reserve tank to the radiator could be plugged up or you have a loose radiator cap or a bad seal causing the tank to hold whats in it. The coolant system is a pressurized system and if a seal is bad or a line is plugged you will experience this problem for the pressure is not there to take whats needed from the tank to deploy in the coolant system

Cooling system problem


well it might overheat because air got into system, replace the thermostant and then fill system, run van keepin an eye on the temp, it will start to run hot because coolant has not filled the motor just the radiator, when it starts running hot shut it down, wait 3 minutes and start, now this is done with cap off,after restart coolant should get sucked in get filling radiator as needed,may get messy but got to bleed cooling system. hope thius helps.

Replaced water pump, alternator, radiator, crank sensor and no coolant leaks and car has antifreeze, but why is low coolant dashboard indicator light keep flashing on 97 saturn sl2


Inside the coolant reserve tank there is a sensor for coolant level.


Over time,this sensor can get stick.


Inspect the coolant reserve tank for crack or leak.

Locate the coolant level switch/sensor and soak it in clean warm water.

Make sure it's free to move up and down the float path.

Top off the coolant tank with coolant only.
