DENSO Radiator – Manual Transmission • DRM44015

Suitable for Mazda MX-5 Mk1 / NA 1.6 and 1.8 petrol models with manual transmission.

DENSO DRM44015 is a direct-replacement engine cooling radiator for manual-transmission Mazda MX-5 Mk1 / NA models. DENSO lists this radiator for both the 1.6 and 1.8 petrol engines, with Mazda OE references including B61P-15-200 and BPE8-15-200.

The radiator is 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

DRM44015 is specified for manual-transmission MX-5 Mk1 / NA applications. Automatic-transmission cars can use a different radiator configuration, so this radiator should not be assumed suitable for an automatic vehicle.

Typical Reasons for Replacement

A radiator may require replacement because of coolant leakage, deterioration of the plastic tanks, corrosion, impact damage, damaged cooling fins or deterioration of the radiator core. 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.

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

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

Other Items to Consider

• Correct specification engine coolant
• Upper and lower radiator hoses
• Radiator hose clips
• Radiator pressure cap
• Thermostat and gasket
• Engine water pump where condition or service history warrants inspection

Useful Tools / Consumables

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

Difficulty Guide

DIY Difficulty: Moderate. Radiator replacement requires draining and subsequently refilling the engine cooling system, disconnecting the coolant hoses and removing the radiator assembly. Correctly bleeding the cooling system after installation is important.

Installation Notes

Only work on the cooling system when the engine is completely cold. Drain the coolant safely before disconnecting the radiator and transfer any reusable mounting rubbers, brackets or ancillary components required for installation.

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