FAQ for Other Repair Info

Q: What should be noted when removing the Radiator Cap?
A:
You should be careful not to remove the Radiator Cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if the radiator cap or surge tank cap is removed while the engine and radiator are still hot.
Q: How to install the Cooling Fan Relay?
A:
You should install the Cooling Fan Relay and the underhood electrical center cover.
Q: How to install the Radiator (LH6, LS2) (5.3L and 6.0L)?
A:
You should install the following parts: the Radiator, the condenser, the bolts retaining the condenser to the radiator, the coolant recovery line, the air inlet grille, the cooling fan, the radiator hose, and the lower radiator support shield. In addition, you should connect the transmission cooler lines to the radiator and fill the cooling system.
