Coolant Leak Indicator 1
The oil analysis may indicate positive glycol, but the sodium levels do not show any increase. An oil analysis of a sample of the new oil that was used in the engine should be made. Some new oils have additives which will give positive glycol results.
Clean-Up Procedure 1
No coolant leak has occurred and no further action is required.
Coolant Leak Indicator 2
The oil analysis indicates positive glycol and the sodium level in the oil has also increased. Examine the oil filter for any signs of metal particles or heavy residue on the filter surface. If none exist, repair the source of the leak.
Clean-Up Procedure 2
Change the oil and filter. No other clean-up is required since the amount of coolant in the oil was limited. But, continue to check the oil filter for any residue or metal particles at 50 hour intervals during the next oil change period to be sure the problem has been corrected.
Coolant Leak Indicator 3
The oil analysis indicates positive glycol and the sodium level in the oil has also increased. Some water in the oil may also be noted. The oil and the filter now indicate a heavy, tacky, black or gray residue, but no sign of metal particles are evident. Customers who do not do oil analysis will usually find the coolant leak in this manner. This is a situation where coolant has leaked into the engine oil.
Clean-Up Procedure 3
a. Find and repair the coolant leak.b. Drain the oil and install new filters. Fill the engine crankcase with a mixture of 75% API CF-4 SAE 15W40 oil and 25% butyl cellosolve. Do not mix more than the 25% butyl cellosolve or use a lower viscosity oil. The resulting mixture viscosity will be too low to provide proper lubrication. Butyl cellosolve is a strong liquid solvent and extreme care should be used when handling it. Keep it off of your hands because it can cause skin injuries. Butyl cellosolve will damage any finished surfaces. In the event of spillage, flush the are with clean water immediately.Butyl cellosolve can be obtained through sales offices of the Carbide and Carbon Chemicals Co., a division of Union Carbide and Carbon Corporation.
c. Remove the radiator cap to keep the coolant system pressure at a minimum. Start and operate the engine until the jacket water temperature causes the coolant thermostats to open. (It may be necessary to block air flow through the radiator.) Run the engine at 75% of High Idle and NO LOAD to maintain the jacket water temperature and keep the thermostats open. Continue to operate the engine at this condition for approximately 20 minutes. This will allow the butyl cellosolve to dissolve the sludge in the lubrication system.d. Stop the engine and drain the oil and solvent mixture from the engine. An assessment can now be made as to the effectiveness of this cleaning process.e. Inspect the oil filters for any sign of metal particles which are an indication of engine damage. If any particles
