DENSO Radiator – Manual Transmission • DRM44008

Suitable for Mazda MX-5 Mk3 / NC 1.8 and 2.0 petrol models with manual transmission.

DENSO DRM44008 is a direct-replacement engine cooling radiator for manual-transmission Mazda MX-5 Mk3 / NC models. DENSO's application catalogue lists this radiator for both the 1.8 and 2.0 petrol engines, with Mazda OE reference LFG7-15-200G.

The radiator forms the main heat exchanger within the engine cooling system. Hot coolant passes through the radiator core, where heat is transferred to the surrounding airflow before the coolant returns to the engine.

Important Transmission Note

DRM44008 is the radiator specified for manual-transmission MX-5 Mk3 / NC applications. DENSO lists a different radiator, DRM44009, for the corresponding automatic-transmission applications. Do not assume the two versions are interchangeable.

Typical Reasons for Replacement

A radiator may require replacement because of coolant leakage, corrosion, impact damage, damaged cooling fins, deterioration of the radiator structure or reduced cooling efficiency. Cooling-system faults should be correctly diagnosed before replacing components.

Fitment Advice

Before installation, compare the replacement radiator with the unit removed from the vehicle, paying particular attention to the hose connections, mounting points and overall configuration. This is especially important on imported, modified or previously repaired vehicles.

When replacing the radiator, inspect the condition of the upper and lower radiator hoses, hose clips, expansion tank, thermostat and surrounding cooling-system components. Any aged or damaged parts are worth replacing while the cooling system is drained.

Other Items to Consider

• Correct specification engine coolant
• Upper and lower radiator hoses
• Radiator hose clips
• Thermostat and thermostat housing
• Coolant expansion tank
• Radiator pressure cap

Useful Tools / Consumables

• Suitable socket and spanner set
• Hose-clip pliers
• Coolant drain container
• Correct specification replacement coolant
• Cleaning materials for any spilled coolant

Difficulty Guide

DIY Difficulty: Moderate to Advanced. Replacing the radiator requires draining and subsequently refilling the engine cooling system, disconnecting coolant hoses and removing the radiator from the vehicle. Correct bleeding of the cooling system after installation is essential.

Installation Notes

Only work on the cooling system when the engine is completely cold. Drain the coolant safely before disconnecting the radiator, transfer any reusable ancillary components required for installation and ensure all hose connections and mounting points are secure before refilling.

Refill using the correct coolant specification and follow the appropriate cooling-system bleeding procedure. Check carefully for leaks and confirm correct coolant level and operating temperature after installation.

For imported, modified or previously repaired cars, matching the part number or component style on the part being replaced is recommended.
