How does radiator design affect coolant flow?
Effects of Radiator Design on the Cooling System. A cooling system whose heat load and coolant flow rate results in a 10 degree F coolant temperature drop through the radiator will have that same coolant temperature drop w hether the radiator has a very small face area and flat fins or a very large face area and louvered fins.
When do you draw coolant back into the system?
When the system cools down you’ll see the system draw coolant back into itself from the over flow if it needs to. After it cycles the first couple of times, you may need to fill your overflow up a little to make up the difference. If there is a large amount of difference, you probably didn’t bleed your system correctly.
Why is there no coolant in the overflow tank?
As the coolant flows through the radiator, excess heat is bled off which allows the boiling point to not be reached. Should you put no coolant in the overflow tank when refilling the system with cold coolant to leave enough room for thermal expansion ?
What should the flow rate of coolant be?
Coolant Flow Rate. The ideal coolant flow rate is one that will provide optimum coolant flow velocity through the radiator tubes in the range of 6 to 8 feet per second. Flow velocities above 10 feet per second should be avoided.
What causes coolant to overflow from the radiator?
Your problem may simply be a loose or damaged cap not keeping coolant where it needs to be. The radiator cap is designed to allow access to fluids in a ‘closed’ system. The coolant used to cool the engine does so at maximum efficiency when kept at specific pressure. Check your owner’s manual for proper cap replacement.
Where is the coolant reservoir on a car?
Engine overheating Average rating from 129,829 customers who received a Vehicle Engine Cooling Inspection. The coolant reservoir is the plastic reservoir mounted in the engine bay that stores the coolant for the engine.
Where did the coolant go?
The coolant reservoir is the plastic reservoir mounted in the engine bay that stores the coolant for the engine. Coolant reservoirs are required because engines go through cycles of expelling and absorbing coolant as they warm up and cool down.
What happens to the coolant when the engine is cold?
When the engine is cold, the pressure of the cooling system is low and more coolant is required, and when the engine is warm the pressure of the cooling system is increased and therefore less coolant is required.
