Application and Buying Notes

Before ordering, confirm the vehicle is a Toyota Yaris NCP130 or 131R with a 1.3L or 1.5L engine from 2011 onwards, as that is the application listed for this Denso TXX3700 TX valve. Even within the same model range, air conditioning components can differ by system layout, so the part number and fitting sizes should be checked against the removed valve.

The 1.5 tonne rating is another detail worth noting when matching the valve to an existing setup. That rating, along with the block pad TX style, helps identify the correct hardware for the system, but it does not replace a proper part number check. The safest approach is to compare the removed valve, the vehicle details, and the listed TXX3700 identification before fitting.

This part is sold each and carries a one year warranty. For a climate control component such as a TX valve, it is sensible to inspect the surrounding system condition at the same time, including the connections and associated parts, so the replacement is not compromised by an unrelated issue in the air conditioning circuit.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number TXX3700 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

For part number TXX3700, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a air conditioning tx valve in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include MITSUBISHI TRITON, MITSUBISHI TRITON 2015, TOYOTA YARIS, TOYOTA YARIS 2010, TOYOTA YARIS 2011, TOYOTA YARIS 2012. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm fitment by matching part number TXX3700, the Toyota Yaris NCP130 / 131R 1.3 & 1.5L 2011 onwards application, and the stated fitting sizes before purchase.
