What causes a coolant reservoir to leak in a car?
When your car cools, the excess coolant will cool as well and return back to the radiator, typically leaving the reservoir tank 1/3 full. A crack in the coolant reservoir could cause a slow leak of coolant and could also cause your car to overheat. You can easily diagnose and fix a coolant reservoir tank leak.
Why does the radiator cap keep coolant from boiling over?
The radiator cap allows the pressure to build inside the engine as the coolant heats up until it reaches about 15-16 pounds (a typical cap rating). Since pressurized fluid boils at a higher temperature than room temperature fluid, that allows the system to operate a higher temperatures without boiling over.
What was the coolant leak and empty expansion tank?
After a bit of a thrashing over the hot weekend I checked the coolant and the overflow bottle had completely overflowed and the expansion tank was completely empty. Alarm bells ringing at this point. The expansion tank had been fitted with a new 15psi cap shortly after I bought the car.
What should I do if my coolant tank leaks?
Use the water hose to wash the tank thoroughly inside and out. You will need to let the tank dry completely. Lightly scuff the cracked area with sandpaper for better epoxy adhesion. Blow sanding particles off area to be patched. Mix the epoxy and allow it to set up according to the manufacturer’s instructions.
What to do if coolant is leaking from Radiator?
Even with the issue only having a random issue, there is a easy trick to figure out which one it is. Here is what to do. Get a empty two liter bottle and fill it half way with plain tap water. Remove the cap at the reservoir and put on a radiator pressure tester.
Can a faulty radiator cap cause coolant to overflow?
A faulty radiator cap can cause the coolant reservoir to overflow and overheating the vehicle’s engine system. If the radiator hoses are always transporting hot fluid, then the hoses will wear out and will finally tear.
When your car cools, the excess coolant will cool as well and return back to the radiator, typically leaving the reservoir tank 1/3 full.

What does it mean when your Radiator reservoir is full?
Suppose you notice that your radiator is empty, but your coolant reservoir tank is full. In that case, it might mean that there is or there are few damages in the components of the engine cooling system, which means that there is possibly a faulty radiator or radiator hose, a damaged gasket, or a radiator cap, or some other faulty components.
