Volvo L105 / L120G Wheel Loader Parts - Radiator, Brake Seal and Bucket Tooth Wear List for Poland and Eastern Europe
Why Polish and Eastern European fleets replace cooling parts first
Poland and the neighbouring markets run loaders through wet winters with heavy road salt and dry, dusty summers. The L105 and L120G cooling package sits directly in that cycle: salt spray attacks the core fins from outside while dust packs the matrix from the fan side. Airflow drops, the machine runs hotter, and the extra thermal cycling hardens every hose and seal in the circuit.
The resulting failure chain is: core externally blocked, temperature creep under load, hoses harden and crack at the clamps, coolant loss, then head and liner damage if the operator keeps running. Most fleets notice the problem only when the low coolant lamp comes on, which is already late.
| Area | Symptom on site | First free check | Usual action |
|---|---|---|---|
| Radiator | Coolant loss, temperature creep, wet core | Pressure test and fin inspection | Replace radiator |
| Intake / charge hose | Boost loss, black smoke, whistle | Squeeze test and clamp check | Replace hose |
| Brake piston seal | Brake drag, hot hub, pedal creep | Hub temperature after a run | Replace seal |
| Bucket teeth | Poor penetration, rounded tips | Wear length against new tooth | Replace teeth |
| Throttle actuator | No response, limp mode, erratic idle | Connector and linkage inspection | Replace actuator |
Radiator 16027916 - pressure test before you order
16027916 radiator is the L105 cooling core. Two failures dominate: external blockage from dust and salt, and tube seam leaks after years of thermal cycling. Before replacing, pressure test the core and check the cap and thermostat, because a stuck thermostat produces the same temperature complaint for a fraction of the cost.
When the core does need replacement, clean the whole cooling stack and check the fan shroud at the same time. A new radiator behind a blocked oil cooler still runs hot, and Polish fleets lose more hours to that mistake than to any other cooling fault.
Hose 17006300 - the boost leak nobody finds
17006300 hose connects the turbocharger outlet to the air filter housing on the L105. It lives in the hottest, most vibration loaded corner of the engine bay, and it fails from the inside: the reinforcing cords separate, the wall softens, and the hose collapses under boost.
Symptoms are easy to misread as an injection fault: black smoke under load, lost power, a whistle that changes with throttle. Squeeze the hose cold; if it feels soft or you can feel a bulge, replace it. Check the clamps and the filter housing mount as well, because a loose housing cuts the hose.
Brake seal 17218537 - winter salt kills it
17218537 brake piston seal is used in the Volvo loader brake caliper assembly. In Poland the killer is road salt: the piston bore corrodes, the seal lip hardens, and the brake starts to drag instead of release. The driver reports poor acceleration and higher fuel use, not a brake problem.
Check by feeling hub temperature after a normal working cycle. One hot hub among four means a dragging brake. Fix it with a seal kit and a bore clean before the disc and bearing are damaged; a dragging brake can destroy a wheel bearing within a few hundred hours.
Bucket teeth 11417126 and actuator 15141094
11417126 bucket teeth are the L120G tooth option used on abrasive aggregate and demolition work. Tooth wear is not linear: once the tip rounds off, penetration load rises and the whole bucket and linkage take the extra stress. Measure wear length at every service and replace as a set, not one at a time.
15141094 actuator (with 17502366) is the throttle actuator on the L110 to L150 loader family. Moisture ingress into the connector is the usual failure in a wet climate, producing no throttle response, limp mode or an erratic idle. Reseat and dry the connector first, then replace the actuator if the fault returns.
Lead time, documents and packing to Poland
Stock items leave the warehouse the same day. Air freight to Warsaw, Krakow, Gdansk and Katowice normally takes 5 to 8 working days. Radiators and heavy assemblies travel by sea or road groupage into Gdansk and Hamburg, with schedules confirmed per order. Shipments use fumigation free pallets or wooden cases with machined surfaces protected, and each order ships with a packing list, warehouse photos and a loading video together with the commercial invoice and packing list required for EU clearance.
To quote, we need three things: the machine serial plate photo, the old part nameplate photo and the installation position. With all three we confirm fitment and reserve stock the same day.
Frequently asked questions
Will an L105 radiator fit an L120G?
Not as a rule. Core thickness, inlet position and mounting differ between the L105 and L120G cooling packages and can also change within a serial range. Send the serial plate photo and the old radiator nameplate so the correct core is confirmed.
Engine overheating - radiator or thermostat?
Pressure test the core and check the thermostat before ordering a radiator. A stuck thermostat and an externally blocked core both show as temperature creep. Cleaning the whole cooling stack often restores performance with no parts at all.
Do bucket teeth have to be replaced as a set?
On abrasive aggregate work, yes. Mixed wear changes the digging angle and loads the bucket and linkage unevenly. Replace as a set and check the adapters at the same time, because a worn adapter wears out a new tooth quickly.
How long does delivery to Poland take?
Stock items leave the same day and reach Warsaw, Krakow, Gdansk and Katowice in about 5 to 8 working days by air. Radiators and heavy assemblies move by sea or road groupage into Gdansk and Hamburg, with packing list and loading photos before departure.
