Parts for your 2008 Toyota Hilux surf-Heater tap

2008 Toyota Hilux Surf heater tap: what’s actually fitted?

The factory Repair Manual for the 2003–2009 Hilux Surf/4Runner platform specifies constant coolant flow through the heater core, with cabin temperature managed by the air mix (blend) damper and its servo motor, not by a water shut-off valve. The Toyota Electronic Parts Catalogue for GRN215/KUN215 variants lists a “Valve Assy, Water, Heater” only on vehicles optioned with a rear heater
