Oil coolers
In all engines it is necessary to ensure the stable operation of the oil cooler

Ryan's Radiator Service can supply and fit or even custom install a new oil cooler into your car. The importance of this is just as important as the rest of your cars cooling system for without it you will cause a lot of damage to vital engine components.

Transmission Oil Cooling

Automatic transmissions generate large amounts of heat and are totally dependant on the transmission fluid for cooling. When the fluid temperature exceeds 93°C the fluid deteriorates rapidly, diminishing its ability to lubricate and cool critical valves, springs, seals and other internal components, leading to premature failure and costly repairs. Over 90% of all automatic transmission failures are caused by overheating. A 10% drop in fluid temperature can double the life of the transmission!

The factory fluid cooler is located in the radiator's coolant holding tank. The hot transmission fluid is cooled by transferring its heat to the colder engine coolant that surrounds it. The minimal temperature difference between the two fluids under normal conditions causes little, if any, drop in the transmission fluid temperature.

Ryan's Radiator Service Transmission Oil Coolers perform best when installed in conjunction with the factory cooler and mounted in front of the radiator. With cool fluid re-entering the transmission, the valves, springs and seals perform as intended, resulting in smoother operation, positive shifts, lower floor board temperatures and extended life.

If you use your vehicle for towing, drive in stop-and-go traffic, or carry heavy loads, your transmission needs an efficient Transmission Oil Cooler. If you drive a recreational vehicle, a street machine with a high-performance automatic transmission, or a race car, you also need a Transmission Oil Cooler.

Engine Oil Cooling

Almost one third of the heat generated by the engine must be removed by the vehicle's two cooling systems. That's correct your engine has two cooling systems. (1) The top of the engine: the area around each cylinder in the engine block, the combustion chamber areas in the cylinder heads and the intake manifold, dispel heat through the engine's radiator coolant system. (2) The rest of the engine: the crankshaft, bearings, camshaft, lifters, connecting rods and pistons are only cooled by engine oil.

The ideal operating range for engine oil is 82°C through 93°C. While operating within this range, the oil works as a lubricant, coolant, and cleansing agent in the engine. Modern engines generally run with radiator coolant temperatures between 90°C and 105°C with oil temperature ranges up to 25°C HOTTER. In other words, when the engine is performing flawlessly, the engine oil is already overheating! Oil that exceeds 105°C rapidly loses its ability to lubricate and cool causing accelerated fatigue and premature component failure.

Ryan's Radiator Service oil cooler coils are engineered for maximum cooling efficiency with no restriction in oil flow.

Benefits are:

Longer engine life
Reduced heat load on engine and radiator
Increased oil system capacity
Lower under-bonnet temperatures

At wide open throttle and full boost the hot compressed air coming from a turbocharger is probably between 120 and 200 deg Celsius depending on the particular turbo, boost pressure, outside air temperature, etc.. This needs to be cooled down, which reduces its volume so more air molecules can be forced into the cylinder so as to avoid detonation.
