Warranty
Heads are warranted for a period of 12 months or 20 000 kms which ever comes first. The warranty covers defects in material or manufacturing. No warranty if overheated electrolytes. Do not under any circumstances earth the radiator core as this creates electrolysis.

Recommended Extras
There are 3 common parts that cause the yd25 to lose coolant and overheat.

Radiator top tank: We have seen the header tank hose barb on the side of the radiator cap mount fail as low as 110k kms. These failures result in total coolant loss within a few minutes. To check the radiator top tank, remove the cap (when cold) and look and feel for brown blemishes in the cap mount. If in doubt, talk with a radiator specialist about replacing the top tank.

Upgraded heater hose kit: Heater hose plastic fittings and oil cooler hoses. We do an upgraded heater hose kit that includes new oil cooler hoses Click the here to go to the upgraded heater hose page

EGR delete pipe kit: Egr pipes are prone to cracking internally in the heat exchanger causing loss of coolant Click here to go to the EGR delete pipe page
