Changes: Engine Coolant HeaterValve

Revision as of 07:40, 12 May 2021

It appears the intended DesignLifeTime for this vehicle, assembled in 2000, was engineered for around 18yrs;
starting in 2019, during nearly each Coolant system maintenance routine (ThermoStatValve, Hoses, FlushFill...)
yet another original plastic part (ThermoStatHousing, HoseTeeFitting, RadiatorSideTank...) cracked & leaked. In
2020July, after installing new hoses into & out of the HeaterValve, it began leaking. Like the ThermoStatHousing
& Radiator, the Plastic Valve was replaced with an AllMetal Valve, pic below, common on 1970s+1980s vehicles.
