The radiator reserve tank is commonly mounted on one of the front fenders. The tank will have a hose connecting it to the radiator.
Overflow tank only
Not much actually.
sounds like blockage in the cooling system. See if you are not low on coolant in the radiator. Just because your reserve tank has coo;ant does not mean that you have enough coolant in the radiator. If you have low coolant in the radiator, it will blow cold. It can happen abruptly. If you are low on coolant in the radiator and not in your reserve tank you will need to find out why the system is not pulling coolant out of the reserve tank.
through the reserve tank which is also called the overflow tank being that there is no radiator cap!
When you add engine coolant to a 2003 Jeep Grand Cherokee because the low coolant indicator has come on, you should add to the reserve tank and the radiator if they are low. Sometimes, just the reserve tank needs filled.
The radiator pushes water into the reserve tank to maintain optimal coolant levels and manage excess pressure within the cooling system. As the engine heats up, coolant expands and can overflow into the reserve tank. When the engine cools down, a vacuum is created that draws the coolant back into the radiator, ensuring consistent circulation and preventing overheating. This process helps protect the engine from damage and maintains efficient temperature regulation.
looks like cilinder head gasket is defect, engine pressure is coming in radiator, and cooling fluid goes into motor
Yes but you should check both if you have a rad that opens. If the rad is low it will be drawn in immediately leaving no reserve and it is intended as a reserve.
The best indication of a bad thermostat is when the radiator fluid (Antifreeze) boils over from the reserve tank, not the radiator. This is caused by the thermostat not opening at its preset temperature and all the extra antifreeze is pumped directly to the reserve tank. You will also have loss of power and the vehicle will likely stop running soon after the antifreeze boils over.
No, shake bottle of sealant well - pour directly into radiator and run engine for approx 15-20 minutes so it can seal properly in the system.
either radiator or pressurized reserve tank. or a coolant hose high on engine will bleed the system for you too.
It does not have a reserve switch - it has a sensor in the reserve tank that turns a light on on the dash when you are low on fuel.
