Why does my Jeep Cherokee not have a thermostat?
(I.e., not letting coolant sit in the radiator/block long enough to transfer heat) Let’s go off of the assumption that all fans are properly shrouded and in good, working condition and the systems are full of a 50/50 mix of antifreeze and water and all air has been purged from the systems.
Where does the coolant come from in an overflow tank?
The overflow tank is connected to an overflow tube that comes from the radiator. This tank provides extra storage space for coolant as it expands when the engine heats up. Without this extra overflow storage space, the coolant would expand and run out from the overflow tube and onto the ground.
How much does it cost to replace a coolant overflow tank?
They are a lot cheaper to fix than replacing the tank itself. Otherwise, the cost to replace a radiator coolant overflow tank is anywhere from $90 to $260.

Radiator Coolant Overflow Tank: Functions, Bad symptoms and Replacement Cost. The purpose of the radiator coolant overflow tank is to prevent your vehicle’s cooling system from forming rust. As you may know, an engine that is working very hard will heat up very quickly. The oil alone is not enough to keep the components of the engine cooled off.
How to tell if your coolant reservoir is overflowing?
How to tell if your over heating problem is caused by the water pump. Faulty water pumps slow or stop the flow of fluid through the cooling system. The result is overheating of the engine. You will see coolant fluid on the ground and around the water pump when the water pump has gone bad. Water pumps either work properly or go bad in a hurry.
What causes a car coolant reservoir to leak?
If the reservoir cracks or develops any small leaks it can cause the coolant it is storing to leak or evaporate at a slow rate. The leaks may be small enough that they may not be obvious to the driver, however, over time they will cause the reservoir to empty out.
Where is the coolant in the radiator when there is no leak?
There’s a COLD/MIN label on the tank indicating the ideal antifreeze level when the engine is cold. The coolant in the radiator should be just below the filler neck. When you are losing coolant but no leak is visible, several parts could be the guilty party.
What should you do when your car is losing coolant but no leak?
Generally, there should be a leak somewhat if the vehicle is losing a high amount of antifreeze. However, a car could be losing coolant but no leak. What should you do when coolant disappearing from reservoir without leaving any trace?
Can a leak in the coolant cause an overheated engine?

What causes coolant to leak from the radiator?
The coolant reservoir collects the hot coolant for recycling back into the radiator once it has cooled down. If you are often adding more coolant to the reservoir, you might have a leak. You might see coolant leaking if the tank is cracked or damaged. If your vehicle leaks too much coolant, your engine can overheat.
What happens when coolant is boiling out of the reservoir?
When this is not functioning properly, the result can be catastrophic overheating of your car’s engine. The fact that the coolant was boiling out of the reservoir cap suggests that the thermostat may be stuck closed. When this happens, the coolant is not allowed to circulate throughout the vehicle’s engine as it should.
What happens when coolant is not maintained in a reservoir?
The real problem creeps in when the appropriate coolant levels are not maintained in the reservoir. Such a decrease in coolant level is evident in the form of leaks or the smell that arises when coolant exits in the form of mist. The real confusion arises when coolant disappearing from reservoir is witnessed without any symptoms.
What happens if your radiator coolant tank cracks?
If the radiator coolant overflow tank is damaged or cracked, then you can expect coolant fluid to leak out of it. Sometimes cracks will form on the overflow tank if it is too old and worn out.
