Thermostat Assembly for Volvo 31293556

Product Overview

Thermostat Assembly for Volvo 31293556 is a direct-reference replacement for the coolant control circuit of Volvo vehicles. It is listed here against OEM 31293556, so the part can be matched to a vehicle without guesswork. The coolant control circuit gives this part a hard life: heat soak, vibration and pressure cycling. Typical end-of-life signs are elements that stick part open and seals that take a set after repeated heat cycles, which reach the workshop as a gauge that never settles in the normal band, higher fuel consumption and thermostat fault codes. The part belongs to a cooling-system catalogue of more than 4000 types, which is the practical reason buyers consolidate a mixed pallet with us rather than splitting it across suppliers.

Key Benefits

• Consolidate the platform in one order — Hoses, flanges and thermostat housings for the same platform ship on one pallet, which shortens the paperwork and the freight bill.
• Tooling route for obsolete references — Where the reference is out of production, we develop the mould from the sample you supply rather than turning the enquiry away.
• Inspection before despatch — Parts are inspected before they leave, which for this family means checking the sealing faces and the connector geometry that decide whether it fits.
• Matched to how the part actually fails — Elements that stick part open and seals that take a set after repeated heat cycles are the reasons this reference is bought, so those are the features checked before packing.

Application Scenarios

Scheduled cooling-system overhaul

The vehicle is in for a coolant leak and the workshop replaces the whole branch at once rather than chasing the next failure in a month. Here the thermostat housing assembly is ordered against 31293556 and travels with the rest of the Volvo branch.

Warranty-expired fleet maintenance

A fleet past dealer coverage moves to independent supply and needs the same reference coverage at a working price. On this reference that means quoting 31293556 with the quantity and letting the packing follow.

Counter stock for a busy platform

Volvo volume in the region justifies holding the line on the shelf instead of ordering it in per job. On this reference that means quoting 31293556 with the quantity and letting the packing follow.

Who It Is For

• Fleet and bus operators — running Volvo vehicles past warranty and buying cooling-system parts by the box to keep downtime short. They judge 31293556 on one thing: whether it matches the part that came off.
• Radiator and cooling specialists — rebuilding cooling systems and sourcing the hoses, flanges and housings for a platform in one go. What they need from 31293556 is that it fits the Volvo on the ramp today.
• Exporters and consolidators — shipping mixed cooling-system pallets into Europe, the Middle East and South America. They judge 31293556 on one thing: whether it matches the part that came off.

Problems It Solves

Returns from wrong fitment

Every returned part costs the freight twice. Checking the opening temperature, the housing outline and whether the unit is map-controlled before despatch is cheaper than a credit note. That is why 31293556 carries its full cross-reference set on this page.

Long lead times on slow movers

A slow line ordered alone waits for a container. Consolidated with fast movers it travels on the same shipment. For Volvo buyers it is the difference between a stocked line and a credit note on 31293556.

Unclear compound

Confirm the compound against the reference before ordering, because visually identical parts are moulded in different materials. For Volvo buyers it is the difference between a stocked line and a credit note on 31293556.

Technical Features

The part serves the coolant control circuit and carries the wax element, housing, seals and — on mapped units — the heater and temperature sensor that govern warm-up. Material for this reference is confirmed per enquiry. The listed opening temperature is 90°C, which is the figure that has to match the vehicle.

Values marked TBC are not stated on the source catalogue. They are confirmed in writing on the quotation rather than estimated here.

Comparison With the Alternatives

Use Guide

1. Confirm the reference

   Match OEM 31293556 against the number on the part you removed. Do not match on outline alone.

2. Check the interfaces

   Compare the opening temperature, the housing outline and whether the unit is map-controlled before the vehicle is stripped further.

3. Inspect on arrival

   Look for transit damage on sealing faces and connectors. Confirm the compound against the reference before ordering, because visually identical parts are moulded in different materials.

4. Fit with the original clamp style

   Reuse the clamp type the Volvo platform was designed around, and fit any seal or O-ring supplied with 31293556 rather than carrying the old one over.

5. Pressure check before handover

   Refill, bleed the circuit and check for cracked plastic housings at working temperature before the vehicle leaves.
