This Mercedes approved OEM G48 formula is HOAT or Hybrid Organic Acid Technology. This is BLUE in color, low acid, low silicate and phosphate-free. Check the existing color of your coolant. DO NOT MIX WITH YELLOW COOLANT.
This is the latest formula which replaces both Q1 03 0002 (yellow/gold) and Q 1 03 0004 (blue). If you have the old fluid (NOT BLUE), it will require a complete drain and flush, as the old fluid Q 1 03 0002 has been discontinued and superseded by this blue fluid.
Do NOT mix the two different colored fluids together, as they are not compatible.
Before replacing the fan clutch assembly or the fan clutch, you must inspect the fan blades very carefully for any chips, cracks or damage.
Any missing chunks or pieces will result in the fan being out of balance and will mean a very short life for any fan clutch, as it will quickly destroy the bearing in the center of the clutch.
It is recommended that you closely inspect your fan blade when you replace the clutch. A damaged fan blade will cause excessive noise and premature fan clutch failure.
A fan blade with just one small missing section on the blade will cause the fan clutch bearing to wear out very quickly, due to the entire assembly being out of balance. Check it very carefully.
This is a brand new original Mercedes part for all five cylinder engines.
IMPORTANT INSTALLATION INFO: Torque value is 33 ft/lbs or 45 Nm
Clean the mating surfaces and torque the center bolt properly. Lack of clearance in this area makes it difficult to gain access during installation. The radiator should be removed in order to do the job correctly. Failure to do so will allow the fan clutch to slip and freewheel on the pulley.
This premium aluminum core radiator is manufactured by Behr Mahle, OEM supplier to Mercedes Benz for this part.
The Behr Mahle replacement radiator guarantees the same quality fit and performance as the OE radiator it replaces. The radiator core is manufactured using high quality anti corrosive aluminum and fiber glass-reinforced polyamide coolant tanks that are highly resistant to cracking and deformation.
