Maintenance and care
29
Procedure:
D
Mix P3-begesol with water, ratio 1:1
D
Using a spray gun, spray the mixture in
as straight a jet as possible directly into
the radiator fins
D
Let the mixture work for 5 minutes
D
Hose down the radiator with a straight
jet of tap water directly from the front.
In cases of stubborn dirt deposits re-
move the radiator and hose it down di-
rectly from behind. Do not use high-
pressure cleaners (steam sprayers may
be used)
Henkel P3-begesol contains no toxic or
corrosive substances and, if handled
properly, may be used without hesitation.
Cleaning the inside of the cooling sys-
tem
(by authorized specialist personnel)
Investigations have shown that in many
cases the poor condition of the coolant
and / or the cooling system accounts for
damage to the water pump mechanical
seal. The poor condition of the cooling
system is normally due to use of unsuit-
able or no anti-freezing agents and cor-
rosion inhibitor or defect, not early enough
replaced covers for filler neck and working
valves.
If twice in a short time the water pump of
an engine develops leakes or the coolant
is heavily contaminated (dull, brown,
mechanically contaminated, grey or black
signs of a leakage on the water pump
casing, after the defect on the oil cooler)
clean the cooling system prior to remov-
ing that water pump as follows:
a) Drain coolant
b) Open thermostats positively (use short-
circuit inserts), so that the entire cool-
ant circuit is flushed in the cleaning
operation
c) Fill coolant circuit with a mixture of hot
water (min. 50
°
C) and Henkel P 3 neu-
trasel 5265 detergent (1.5% by volume)
(-5266, -5225, Kluthe Hakopur 316),
see Publication “Fuels, Lubricants ...”
d) Warm up engine under load. After a
temperature of 60
°
C is reached, run
engine for a further 15 minutes
e) Drain cleaning fluid
f) Repeat steps c) and d)
g) Flush cooling system. To this effect
h) Replace drain plug by drain plug with a
bore of 8 mm dia
i) Fill cooling system with hot water
k) Run engine at idle for 30 minutes. At
the same time continuously replenish
the water leaking from the bore in drain
plug by adding fresh water
Repair water pump only now. Thereafter,
fill the cooling system with approved cool-
ing fluid. See Publication “Fuels, Lubric-
ants ...”.
Note:
Only sediments and suspended par-
ticles can be removed by this cleaning
method. If corrosion and lime deposits
are found, proceed according to the
following section:
Removal of lime deposits in the cool-
ing system
(by authorized specialist personnel)
Procedure:
D
Drain the coolant
D
Fill the system with undiluted original
pickling fluid (Lithsolventsäure or en-
gine pickling fluid RB-06), see sources
of supply
D
Let the engine run (also in normal oper-
ation) for approx. 8 hours with this fill-
ing in the cooling circuit
D
Drain the pickling fluid and thoroughly
flush the system with tap water
