1618.142 Heater Core for OPEL Astra G and Zafira

1618.142 OPEL Astra G Heater Core – Cabin Heating Replacement

The 1618.142 heater core is an interior-heating heat exchanger referenced for OPEL Astra G and selected Zafira configurations. Cross numbers 9117283 and 72660 help catalogue matching, while the removed heater matrix remains the final installation reference.

Located inside the HVAC housing, this compact radiator receives hot engine coolant and transfers its heat to air moved by the cabin blower. A clean core and correctly sealed pipe connections are essential for dependable demisting and passenger-compartment heating.

When an OPEL Heater Matrix May Need Attention

A sweet coolant smell inside the cabin, mist that returns to the windscreen, damp carpeting or weak heat despite normal engine temperature can indicate leakage or internal restriction. These symptoms should be diagnosed before replacement because hose, thermostat, blower-door and coolant-circulation faults can produce similar complaints.

Fitment Verification for OE 1618.142

Compare 1618.142 and every number on the original component label.

Confirm vehicle model, production year, engine and left- or right-hand-drive HVAC layout.

Measure core height, width and thickness before removing the dashboard assembly.

Check the number, diameter, spacing and bend direction of both coolant pipes.

Inspect foam seals, retaining clips and the heater-box connection method.

Installation and Cooling-System Service

Heater-core replacement often requires access to the HVAC case, so identification should be completed before disassembly. Flush contaminated coolant from the circuit, replace damaged seals and bleed trapped air after installation. The cooling system should then be pressure-checked and the cabin heater tested through a complete warm-up cycle.

Quality and Export Supply

Pre-shipment review can cover fin condition, pipe alignment, core dimensions, sealing surfaces and protective packaging. AutoParts supports sample and wholesale enquiries for repair networks, HVAC-parts distributors and automotive cooling specialists.

For a quotation, provide OE 1618.142, required quantity, destination and packaging request. When fitment is uncertain, include the original label and clear photographs of the heater core and its pipe connections.

Frequently Asked Questions

Does OE 1618.142 fit every OPEL Astra or Zafira?

No. HVAC housings and pipe arrangements can vary by generation, engine, market and steering position. Verify the original unit before ordering.

What is the relationship between 1618.142, 9117283 and 72660?

They are commonly used comparison references for this heater-matrix family. A matching number should still be supported by dimensions and pipe-layout checks.

Why can a leaking heater core cause window fogging?

Coolant vapour and moisture can enter the ventilation air stream, producing a film or mist on the inside of the windscreen.

Can inspection photographs be supplied for a wholesale order?

Photo requirements can be discussed before order confirmation and included in the inspection agreement.

Is customized packaging available?

Neutral cartons and customer-specific labels may be available according to quantity, artwork and packing specifications.
