Error Code 89 John Deere 7930

Model : 7930

How to fix ?

Remove the filter and attempt to tap the debris loose or give it a good clean with a vacuum. You can also use a mixture of mild dish detergent and warm water to dislodge and rid the air filter of any debris. If the dust in the filter is extensive, you should replace it.Do not ever try to open your radiator cap when the engine is hot. The coolant gets pressurized, in addition to being very hot, and can send your cap flying while scalding you with hot steam. We’ve seen radiator caps go flying through windows, into people and high into the air
