OEM and interchange reference: 121850-49810 | 121850-49800 | 121850-49811<\/strong><\/p>\n Use the number from your parts book to confirm interchangeability. If your number is not listed, send it to us \u2014 we cross-check against the parts manual and confirm in writing before you pay, because a wrong part costs far more in freight and downtime than the part itself.<\/p>\n 4TNV94, 4TNV98<\/p>\n Fitment can change on a serial-number break within the same model. Send us the model and serial number from the machine nameplate and we verify it against the parts manual before dispatch.<\/p>\n Heat rejection is a function of core surface area and airflow \u2014 both are easy to get wrong on a 4tnv94 4tnv98 thermostat. We build to the original core specification for Yanmar machines and pressure-test every unit. A core that is 10% undersized holds temperature on a cool day and cooks the engine in summer.<\/p>\n We ship single units worldwide and consolidate full containers for distributors. Every 4tnv94 4tnv98 thermostat is individually boxed and labelled with its part number, and pre-shipment photos and dimensional checks are provided as standard.
