With a Valtra T 203 from the T3 series you are in the right place. Find more than 110 parts that fit, including trailer couplings, lighting and electrics.
When the temperature gauge on a Valtra T 203 starts climbing under load, the cooling system is the first place to look. This page lists more than 110 replacement parts for the T 203, from thermostats and the fan clutch to headlights and a cab door lock. They come from GRANIT, Scharmüller, DANA Spicer, Walterscheid, BOSCH and others.
Work through the system in order. A faulty thermostat often sticks half closed. Next, look at the fan clutch: if the cooling fan barely turns when the engine is hot, the clutch is no longer engaging properly. Check the tensioning pulley as well, because a slipping belt slows down both the fan and the water pump. A temperature sensor giving a false reading can also send you in the wrong direction, so verify with a separate measurement if in doubt.
For lighting there are headlights, an LED headlight and work lamps, and for the cab a door lock. Seals and gaskets include a gasket for the silencer at the turbocharger, seals for a pressure pipe and an O-ring for the oil filler cap. At the rear you can fit a ball type drawbar, and separate balls are available as well.
Your type plate confirms the machine is a T 203. Compare the reference number on the old part with the details shown for the item. On a thermostat that number is often stamped on the rim.
If you are thinking of switching to an LED headlight, check first that the connector and mounting match the existing lamp, so nothing needs to be modified. An LED unit draws less current and has no filament to break from vibration. On a ball type drawbar, a thin film of grease on the ball is enough to keep wear on ball and coupling down. Wipe off old grease mixed with grit regularly, because that mixture acts like grinding paste.
When you replace the thermostat, take a close look at the radiator hoses too, and renew any hose that has swollen or split at the clip.
These models from the same range each have their own page: Valtra T 213, Valtra T 163 and Valtra T 153. Handy if you run more than one Valtra. For the complete line up of the make, visit Valtra parts.
