How does the coolant system in a jeep work?
It keeps the engine block at its optimum operating temperature. When the engine is cold, the thermostat closes to restrict coolant flow to the radiator and allow the engine to quickly reach its operating temperature. As the engine heats up, the thermostat opens and allows coolant to circulate through out the entire coolant system.
What should I do about my Willys Jeep cooling system?
1. Proper coolant level. 2. Poor air flow. Check for dirty radiator core. Check for faulty belt pulley operation, worn or loose fan belt, or damaged fan. Clean, repair, or adjust as needed. 3. Foaming coolant. Check for air leaks at water pump, hose connection and filler cap. Tighten, repair or replace.
What kind of coolant should I use for my Jeep?
There are some lifetime waterless coolants, such as non-aqueous propylene glycol, that offer much improved heat transfer and a much higher boiling point than a 50/50 glycol mixture but they cost in the neighborhood of $32/gallon.
Which is the main drive of the coolant system?
10) Water Pump – The water pump is the main drive of the coolant system. It keeps the coolant in a continuous flow from engine block to radiator and all points in between. There are various designs of the impeller, but the most common design seen is a paddle-style.
Why do you need a coolant system in a jeep?
The fuel system is calibrated to run rich while the coolant temperature is below a certain level. Overfueling for cold running is necessary but it washes down cylinder walls with fuel, dilutes oil, creates carbon deposits, drastically increases emissions and decreases fuel economy.
Why does high coolant flow result in a cooler engine?
Turbulent, high-flow coolant results in a cooler engine because it moves away before it has a chance to boil. Most experts say that coolant flow should be as high as the coolant passages in the block will allow before flow restriction raises the pressure significantly.
Is there a way to lower the coolant temperature?
You can effectively adjust the timing in your older rig to produce a cooler burn, which will drop the engine temperature a few degrees. Finish the tune up with all the usual pieces parts to keep your rig’s motor healthy too. WaterWetter, a coolant system additive from Redline, claims coolant temperature reduction as much as 30ºF.
How is heat absorbed into the coolant system?
Most of the combustion heat, around 1000 degrees Fahrenheit, goes out the exhaust. Some 20-35% of that heat is absorbed into the coolant through the water jackets in the block and head and some is transferred to the oil. If too much is absorbed by the metal parts, you have problems like melted pistons, scored cylinder walls and burned valves.
