Coolant level low light comes on and the coolant level is right


The coolant has to be right to the top of the filler neck. Have you a heating problem. The thermostat may not be working properly and the pump is lowering the water in the top tank enough to set the sensor off. Have the sensor tested for operation.

I have a 2000 Escalade and it's leaking a bit of antifreeze and I can't visually see where it's coming from but seems to be from the front end of the motor. It's not the radiator or any of the main v


I would take a look at the water pump. There is a weep hole on the water pump to indicate if the seals are going bad inside the water pump. This hole is located on the top of the water pump where the pulley mounts to it. If this is not the problem, then it could be a number of other problems.

I would check the following items, which I have listed in sequence of cost to repair.

1. check hoses and clamps, if leaking you should see areas that have build up of dried antifreeze.
2. check thermostat housing on top of intake where upper radiator hose connects to engine.
3. verify radiator is not leaking
4. intake gasket leaking
5. head gasket leaking

The cyl misfire is a clue. most likely you have head gasket leakage. Have a auto shop do a BLOCK-TEST it will test the cooling system for combustion gases.

The coolant is leaking from my cadillac escalade 2002 do u know why


It could be your water pump gasket or thermastate gasket. Have you had any one of them parts replaced recently? They could have put the gaskets on slightly off center causeing it to leak. Find where the leak is coming from. Sometimes the gaskets if old do leak. And if you drive make sure you to watch the temperture gage. Shut off if it gets to hot or you could do damage to your motor. Good luck!
Also if its a slow leak you can put water in it if you not going to get it replaced right away. But make sure to use anti freeze if you think its going to get below 32 degrees soon. Because just water will freeze but for warm weather its a quick fix until you can get it to the mechanic.
