DENSO offers radiator installation tips

With its original thermal technology fitted to almost 40 per cent of European cars, DENSO is the ideal choice for crash repairers when it comes to replacement Radiators.  The 850, OE quality Cooling Radiator references offered by DENSO Aftermarket Sales UK & Ireland for 4,600 vehicle applications are smaller, lighter and offer greater heat exchange efficiency than most other brands.

Check you have selected the correct part number through cross referencing.

Inspect the new part carefully, including the size and fitment of ancillary parts such as caps, switches and sensors before installation.

Carefully examine the radiator hoses and connections, and replace any with new OE parts where necessary.  Failure to do this can cause radiator failure.  The most common problem is coolant leakage resulting from defective or worn seals.

Thermostats and caps are also susceptible to faults.  This is usually due to inherent defects in the radiators, although faults relating to OEM and matching quality replacements are extremely rare.

Avoid cheaper alternatives.  This may sound like simple advice but research has shown that buying cheaper will cost more in the long run as too often cheaper can mean inferior quality.

Be careful to avoid physical damage occurring whilst handling and installing.

Don’t forget to inspect any defective radiator mountings (bushes / rubbers).  These can easily be repaired before installing the radiator.

Coolant antifreeze concentration is also subject to certain regulations as outlined by the vehicle manufacturer.  Be sure to double check this each time you fit a new radiator to ensure that the correct concentration is used.

Remember that the radiator is the heart of the engine cooling system, in that it releases the heat exchanged from the engine into the air.  Because of this make sure you check the performance and operation of the electric cooling fans after the new radiator has been installed.

If in doubt, check the vehicle manufacturer’s guidelines.  All practices and procedures will be available in the technical information that each VM creates for each vehicle they make.  Block Exemption Rules state that this information must be available to installers.

100% OE quality: matches original equipment specification

Pioneering design and technology: delivers ultra-efficient performance – a

DENSO Radiator with a 0.2 sq.m front surface, for example, features more than 6 sq.m of cooling surface on its fins.

Co-developed with air conditioning experts: ability to cope with extreme environmental conditions

Braze welding: ‘closer’ contact between tube and fin for more efficient heat transmission

Mechanical deformation: the tube is ‘pressed’ against the fin, offering slightly less contact but lower production cost

Advanced metals: high level of conductivity and low weight enable even thin surfaces to be machined

Rigorous testing: guarantees long-lasting, efficient performance

Solenoid valves fitted with sensors: only activate the fan when necessary to avoid unnecessary fuel consumption

Accurate fluid dynamics calculations: guarantee increased efficiency while reducing noise
