Overheating Engine
It’s been said that more than half of all engine failures can be traced to cooling system problems. The cooling system is a complex mix of components, and very often one major component is totally overlooked when searching for a solution to overheating problems – the engine lubrication system! After thoroughly checking the usual suspects of an engine cooling system, and often spending large amounts of cash on larger, High Flow big core radiators, hi-efficiency water pumps, new fan hubs, different thermo-fans, ‘performance’ thermostats etc., many operators still experience engine overheating under load, especially with diesel engines.
A major cause of engine overheating…
Were you aware that engine oil plays as just a critical role in dissipating heat from an engine as does the coolant!? Typically, engine oil travels the entire lubricating system of an engine in around 5 seconds. That’s not very much time to lubricate, clean, and cool before it’s returned to the same hostile environment – especially the underside of pistons (the hottest lubricated component). Oil cleanliness is vital, as any sludge can restrict the flow of oil under the pistons and through the oil filter and oil galleries and reduce its cooling effect. Just as important is component cleanliness.
Carbon in piston ring grooves acts as insulation which reduces heat transfer from the ring to the piston, and then to the oil. Deposits on the underside of piston skirts also insulate against heat transfer. The black soot that accumulates in engine oil readily absorbs heat but doesn’t dissipate it easily, and consequently it is a major factor in engine overheating.
Diesel engines often accumulate a large amount of sludge in the lubricating system which retains engine heat. This is a major problem as it greatly inhibits the ability of the engine oil to cool the engine. Black, sooty diesel engine oil means contaminants are critically depleting the cooling efficiency of the oil. It is a myth the all diesel oil should go black straight after a change! Is there any wonder the engine cooling system struggles to keep operating temperatures within limits when the engine lubricating system consists of heat-retaining, often baked-on, sludge and other contaminants that hold on to excessive heat in the engine oil?
That’s the bad news…
Fix chronic overheating with Flushing Oil Concentrate
Here’s the good news – before you spend big bucks on hi-performance components that may only make a very small difference to your engine overheating problem, get to the root of the problem and use Flushing Oil Concentrate to target the most persistent sludge and all hard baked-on carbon and soot to restore pristine cleanliness to all oil-wetted parts of the engine. It’s more than just a rinse; it’s a full-on cleaner, and it solves the exasperating chronic overheating problem. Nothing else matches it. Seriously!

The Overheating Value Pack combines essential products to address the basics of often ignored problems of overheating, including –
- Blocked radiator tubes, scale and rust build up in the engine’s cooling system
- Heavily contaminated oil – a major cause of component overheating
- Sludge and hard carbon on oil-wetted surfaces, causing heat to be retained
- Frictional heat build-up – increases engine temperature dramatically
RMI-25 Cooling System Treatment is a very low-cost, extremely effective defense against cooling system failure in all engines. It is a total pour in/drive-away system which removes rust, scale and corrosion, prolongs component life, prevents water pump and radiator failures.
