*NEW* RADIATOR for MERCEDES BENZ GLE W166 ALL MODELS 2015 – 2017 PETROL & DIESEL

ATTENTION!
Failure to install this radiator assembly without strictly adhering to thefollowing procedures will render void the Radiator Manufacturer’s warranty.

Installation Instructions

Part A

Installing A New Radiator (Replacingold, faulty, or damaged radiator existing in vehicle)

Step 1:   Prior toremoving the existing radiator, the cooling system must be inspected forevidence of stray/electric current (this is only possible when the coolingsystem is still in operation.)

Stray/electric current causes ahighly destructive from of corrosion, electrolysis.  This is caused by thepassage of even the smallest (0.03 volt) current through the coolant in thesystem. 

The resulting fast acting corrosion attacks not only the radiatorand heater cores, but can also cause severe and expensive damage to alloycylinder heads, water pumps, thermostats, and other components and partsincluding the auto transmission.

This condition occurs within thecooling system mainly due to current seeking an easy path through the coolantto ground.  Typically stray/electric current is the result of accidentdamage to the vehicle,

poor installation of electrical components and faultsoccurring in electrical components.

To test for stray/electric current,use an analogue voltmeter with sensitivity of 0.03 volts or a stray currentdetector by first placing the positive lead directly into the coolant (throughthe filler neck on the radiator),

or in the overflow bottle (for a closedsystem), making sure that the terminal is not in contact with any surroundingmetal surface. Then attach the negative lead to the battery earth (negativeterminal), and switch on all of the electrical systems, one at a time.

Firstwith the engine running and then repeating the process with the engine turnedoff.  A reading of more than 0.03 volts or a positive (red light)indicates a damaging current is likely to be present in the cooling system.

This procedure will enable you toestablish by process of elimination the source of any current.  It isimperative that the source of any current traveling through the coolant islocated, repaired or replaced prior to installing a new radiator assembly.

Note: Additional electric accessories can be the source of stray/electriccurrent.  If additional accessories have been fitted or repairsundertaken, repeat stray current check.

DO NOT PROCEED IF UNABLE TOESTABLISH THE SOURCE OF ANY DETECTED CURRENT.  CONSULT A QUALIFIED AUTOELECTRICIAN FOR ASSISTANCE.

Step 2: Completely drain the coolant from the system.

Step 3: Fill the system with water and treat with quality alkaline cooling systemflushing agent. Observe the instructions on the container, ensure that thevehicle’s heater is turned on and that the radiator overflow bottle is clean.

Step 4:Check components such as the radiator cap, hoses, clamps, thermostat, waterpump and fans(s) for wear and current condition.

Step 5:Drain water from system and flush out with clean water.

Step 6: Carefully remove the old radiator assembly and check mountings.

Step 7: Correctly install the new radiator assembly – replace fault or worn components.Check vehicle service manual for any additional procedures applicable toradiator installation.

Step 8: Fill system with clean water and perform stray/electric current test procedureas outlined in Step 1.  Proceed if result is negative.

Step 9: Completely drain water from system.

Step 10: Install the recommended coolant (type and dosage) for this vehicle as specifiedby the vehicle manufacturer’s service manual.  When using a concentrateinhibitor, use distilled or demineralized water.

ATTENTION!
Do not mix any coolant brands together.  Correct coolant selection andinstallation is essential to ensure maximum corrosion protection for allcomponent parts within the engine cooling system.

Coolant/inhibitors are added to thecooling system for three reasons:

1. To increase the boiling and freezing point of the water.
2. To lubricate those moving parts of the engine that are in contact with water.
3. To provide a film barrier between the potentially corrosive water and the various types of metals founds within the engine and cooling system.

The inhibitor continually replacesthe protective barrier as the corrosive elements of the water dissolve thebarrier.  However, because this is a continual process,

thecoolant/inhibitors become depleted after a time to the point where they nolonger provide this protective coating.  Alkaline corrosion can begin on theinside of the radiator tubes

because the coolants/inhibitors from differentmanufacturers have different chemical compounds which may adversely react ifmixed.  It is important not to create a chemical cocktail by mixingdifferent brands of coolant/inhibitor.

Step 11: Run vehicle engine up to normal operating temperature and inspect allcomponents for leaks.

ATTENTION!
Do not remove the Radiator Cap
