Ford Explorer Engine >> INTAKE MANIFOLD COOLANT & VACUUM LEAKS
Intake Manifold Coolant & Vacuum Leaks On
Ford 5.0L, 5.0L HO and 5.8L Engines
Intake manifold coolant and vacuum leaks have been found to be quite common on Ford 5.0L, 5.0L HO (High Output) and 5.8L engines. For this engine, following the proper intake manifold torque values and torque sequence is very critical.
Installation of the aluminum intake manifold should proceed as follows:
Clean all gasket surfaces of debris and oil residue.
Apply a 1/8 bead of silicone sealer in the 4 corners where the cylinder heads
meet the cylinder block (Figure 1).
Install the intake manifold side and end gaskets and apply a 1/16 bead of
silicone sealer in the 4 joints formed by the gaskets.
Mount the manifold and torque the bolts in sequence to 15-20 lbs.ft (Figure 2).
Torque the bolts in sequence to 23-25 lbs.ft.
After the engine has reached operating temperature, retorque the intake
manifold bolts to 23-25 lbs.ft.
