The wet gel can be removed using an alkaline (non-acid) cleaner containing either sodium nitrite
or sodium tetraborate.
If the gel is allowed to dry, it is necessary to disassemble the engine and clean it with a caustic
solution, or physically clean the individual components.
5.3.6
The following types of coolant are not approved for use in MBE 4000 engines:
Antifreeze or coolant containing phosphate can cause dropout, overheating, and damage to
coolant pump seals.
Automotive coolants offer no protection against liner pitting, and generally contain high
levels of phosphate and silicate.
Antifreeze based on methyl alcohol can damage the non-metallic components of the
cooling system. They are not suitable for use with diesel engines because of their low
boiling point.
Antifreeze based on methoxy propanol is not compatible with the fluoroelastomer seals
used in the cooling system.
Glycol-based HVAC coolants contain phosphates which can deposit on hot internal engine
surfaces and reduce heat transfer.
5.3.7
Coolants are biologically degradable substances.
When disposing of used coolant, comply with local legal requirements and waste water
regulations.
Consult the local water supply authorities to determine the best method of disposal.
A modern engine coolant has complex tasks to perform. Do not allow any form of "reprocessing"
which consists only of mechanical purification.
5.3.8
Batteries should receive more frequent maintenance and recharging during the cold season of the
year.
Careful maintenance and low current consumption will help to maintain the full battery charge.
Starting capacity drops severely in cold weather. For example, at 14 F (–10 C) starting capacity
is only about 60 percent of normal. If the engine is shut down or out of use for an extended
period of time, store the batteries out of the vehicle in a heated area if possible. Ensure good
ventilation when recharging.
