Axle Fluid; Brake Fluid; Hoat Coolant - DaimlerChrysler SPRINTER2006 Service Manual

0 - 2 LUBRICATION & MAINTENANCE

AXLE FLUID

Use oils approved to MB 235.0 or 235.6, such as
Shell Spirax MB90, Caltex Hypoid LD, or MOPAR
part number 4874469, or equivalent. An API GL-5/
MIL-2105-E SAE 90 Hypoid Gear Oil may be substi-
tuted. Reduced axle durability may result if an
unapproved product is used.

BRAKE FLUID

Use brake fluid approved to MB 331.0, such as
Intac B026D, MOPAR
number 04549625AC, or equivalent. If the approved
product is not available, use a DOT 4 brake fluid:
minimum dry boiling point (ERBP) 500°F, minimum
wet boiling point (WERBP) 356°F, maximum viscos-
2
ity 1500 mm /s, conforming to FMVSS 116 and ISO
4925.

HOAT COOLANT

WARNING: ANTIFREEZE IS AN ETHYLENE-GLYCOL
BASE COOLANT AND IS HARMFUL IF SWAL-
LOWED OR INHALED. IF SWALLOWED, DRINK
TWO GLASSES OF WATER AND INDUCE VOMIT-
ING. IF INHALED, MOVE TO FRESH AIR AREA.
SEEK MEDICAL ATTENTION IMMEDIATELY. DO NOT
STORE IN OPEN OR UNMARKED CONTAINERS.
WASH SKIN AND CLOTHING THOROUGHLY AFTER
COMING IN CONTACT WITH ETHYLENE-GLYCOL.
KEEP OUT OF REACH OF CHILDREN. DISPOSE OF
GLYCOL BASE COOLANT PROPERLY, CONTACT
YOUR DEALER OR GOVERNMENT AGENCY FOR
LOCATION OF COLLECTION CENTER IN YOUR
AREA. DO NOT OPEN A COOLING SYSTEM WHEN
THE ENGINE IS AT OPERATING TEMPERATURE OR
HOT UNDER PRESSURE, PERSONAL INJURY CAN
RESULT. AVOID RADIATOR COOLING FAN WHEN
ENGINE COMPARTMENT RELATED SERVICE IS
PERFORMED, PERSONAL INJURY CAN RESULT.
CAUTION: Use of Propylene-Glycol based coolants
is not recommended, as they provide less freeze
protection and less corrosion protection.
The cooling system is designed around the coolant.
The coolant must accept heat from engine metal, in
the cylinder head area near the exhaust valves and
engine block. Then coolant carries the heat to the
radiator where the tube/fin radiator can transfer the
heat to the air.
The use of aluminum cylinder blocks, cylinder
heads, and water pumps requires special corrosion
protection. Use coolant approved to MB 325.0, such
as EURO Peak Coolant/Anti-freeze (OLD WORLD
INDUSTRIES), Zerex G05 or G48 (The Valvoline
Company), Glysantin G05 (BASF AG), MOPAR part
number 05066386AA, or an equivalent Extended Life
Brake & Clutch Fluid, part
Coolant with the HOAT inhibitor system. This cool-
ant offers the best engine cooling without corrosion
when mixed with 50% anti-freeze and 50% distilled
water to obtain a freeze point of -37°C (-34°F). If it
loses color or becomes contaminated, drain, flush,
and replace with fresh properly mixed coolant solu-
tion.
CAUTION: This coolant may not be mixed with any
other type of antifreeze. Mixing of coolants other
than specified (non-HOAT), may result in engine
damage that may not be covered under the new
vehicle warranty, and decreased corrosion protec-
tion.
CAUTION: Do not use coolant additives that are
claimed to improve engine cooling.
COOLANT PERFORMANCE
The required ethylene-glycol (antifreeze) and water
mixture depends upon climate and vehicle operating
conditions. The coolant performance of various mix-
tures follows:
Pure Water-Water can absorb more heat than a
mixture of water and ethylene-glycol. This is for pur-
pose of heat transfer only. Water also freezes at a
higher temperature and allows corrosion.
100 percent Ethylene-Glycol-The
inhibiting additives in ethylene-glycol need the pres-
ence of water to dissolve. Without water, additives
form deposits in system. These act as insulation
causing temperature to rise. The increased tempera-
ture can result in engine detonation. In addition, 100
percent ethylene-glycol freezes at -22°C (-8°F).
50/50 Ethylene-Glycol and Water-Is the recom-
mended mixture, it provides protection against freez-
ing to -37°C (-34°F). The antifreeze concentration
must always be a minimum of 44 percent, year-
round in all climates. If percentage is lower, engine
parts may be eroded by cavitation. Maximum protec-
tion against freezing is provided with a 68 percent
antifreeze concentration, which prevents freezing
down to -67.7°C (-90°F). A higher percentage will
freeze at a warmer temperature. Also, a higher per-
centage of antifreeze can cause the engine to over-
heat because specific heat of antifreeze is lower than
that of water.
CAUTION: Richer antifreeze mixtures cannot be
measured with normal field equipment and can
cause problems associated with 100 percent ethyl-
ene-glycol.
