Product description

The thermostat for Yanmar engines, such as the 4TNV94, 4TNV98, D94LE, D94E, D98E, 4TNV84 and 4TNV88 , is a key element of the cooling system. It is responsible for maintaining the optimum operating temperature of the engine, which affects its efficiency and durability. At a temperature of 76 ° C , the thermostat opens, allowing the flow of coolant, which prevents the drive unit from overheating. Made of durable materials, it guarantees long service life and trouble-free operation in difficult conditions.

Questions & Answers

Why is regular filter replacement (oil, air, fuel) crucial for a mini tractor?

User

Regular filter replacement is the easiest way to extend the life of an engine from brands like Kubota or Yanmar. The oil filter removes metallic contaminants generated during operation, the air filter protects the cylinders from field dust, and the fuel filter prevents water and dirt from damaging the precision injection system. We recommend replacing filters every 50-100 operating hours or at least once per season to ensure optimal engine performance.

How to properly select and sharpen mower blades for a Japanese tractor?

When selecting mower blades, consider the mower deck model and the blade length and center bore diameter. Maintaining blade balance is crucial when sharpening – an unbalanced blade causes vibrations that damage the hub bearings. Remember that sharp blades mean healthier grass, a cleaner cut, and less strain on the engine of your Iseki or Mitsubishi tractor.

How to identify the correct V-belt size and how to care for it?

User
Ekspert Traktor.com.pl – Doradca techniczny • 17.02.2026
It's best to read the markings on the side of the old V-belt. If they are illegible, measure the belt width and its outer length (La). On Shibaura and Hinomoto tractors, it's important to regularly check the belt tension – too loose a belt will cause slippage and faster wear, while too tight a belt can cause alternator or water pump bearing failure.
