RE: Coolant, runs hot questions????
Cooling System, Draining, Filling and Bleeding
1. Note: Some coolant/water will be retained in the cylinder block (6010) if cylinder block drain plugs are not removed. When refilling cooling system after flushing, adjust coolant mix ratio to obtain a 50/50 mix. Be certain to account for approximately 4.8 liters (5.1 quarts) of water left in the cylinder block when drain plugs are not removed.
Bring engine to normal operating temperature and turn engine OFF.
2. Remove engine appearance cover.
3. WARNING: NEVER REMOVE PRESSURE RELIEF CAP UNDER ANY CONDITIONS WHILE ENGINE IS OPERATING. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN PERSONAL INJURY AND/OR DAMAGE TO THE COOLING SYSTEM OR ENGINE.
WARNING: TO AVOID BURNS FROM SCALDING COOLANT OR STEAM, USE EXTREME CARE WHEN REMOVING THE PRESSURE RELIEF CAP.
Drain cooling system as follows:
a. If cooling system is still hot, carefully wrap a thick cloth around the pressure relief cap and rotate slowly until pressure begins to release. Step back until the pressure is released.
b. Then rotate pressure relief cap until free. Remove the pressure relief cap.
c. Open radiator draincock (8115) and disconnect engine coolant return hose at coolant inlet connection on oil filter adapter (6881) to drain the coolant system.
4. Note: A 50/50 mixture of Premium Cooling System Fluid E2FZ-19549-AA or B (in Canada, Motorcraft CXC-8-B) or equivalent meeting Ford specification ESE-M97B44-A and water is required to prevent damage to the cooling system.
Fill cooling system as follows:
a. Check all hose clamps for proper tightness. Make sure radiator draincock is closed.
b. Place heater temperature selector in maximum heat position.
c. Remove cooling system fill plug from engine water bypass tube.
d. CAUTION: Do not fill cooling system through reservoir only. Coolant will not enter engine. Only radiator coolant recovery reservoir (8A080) and radiator (8005) will be filled and engine overheating will occur.
CAUTION: Use extreme care to keep coolant mixture off of the drive belt and pulleys. If needed, remove drive belt (8620) and rinse with clear water. Clean pulleys and install drive belt. Belt squeal and early belt fatigue will occur otherwise.
Add coolant into fill neck on water bypass tube until coolant reaches "FULL" mark on radiator coolant recovery reservoir.
e. Reinstall pressure relief cap to radiator coolant recovery reservoir.
f. Slowly continue to fill cooling system at water bypass tube fill neck, allowing air to escape, until full.
g. Start engine and run at idle. Add a 50/50 mixture of Ford Premium Cooling System Fluid E2FZ-19549-AA (in Canada CXC-8-B) or equivalent meeting Ford specification ESE-M97B44-A and water at water bypass tube fill neck until full.
h. Reinstall water bypass tube fill plug. Tighten fill plug to 15-18 N-m (11-13 lb-ft).
5. Bleed cooling system as follows:
a. Select maximum heater temperature and fan speed settings. Position control to discharge air at A/C registers in instrument panel.
b. WARNING: TO AVOID THE POSSIBILITY OF PERSONAL INJURY OR DAMAGE TO THE VEHICLE, DO NOT OPERATE ENGINE WITH HOOD OPEN UNTIL FAN BLADE HAS BEEN FIRST EXAMINED FOR POSSIBLE CRACKS AND SEPARATION.
Start engine and allow to idle. While engine is idling, feel for hot air at A/C registers.
c. CAUTION: If air discharge remains cool and engine temperature gauge does not move, engine coolant level is low in engine and must be filled. Stop engine, allow to cool and fill cooling system as outlined.
Start engine and allow to idle until normal operating temperature is reached. Hot air should discharge from A/C registers. The engine temperature gauge should maintain a stabilized reading in the middle of the "NORMAL" range and the lower radiator hose (8286) should feel hot to the touch.
d. Shut engine off and allow to cool.
e. Visually check engine for coolant leaks.
f. Note: When low coolant warning message flashes, approximately 0.946-1.416 liters (1-1.5 qts.) of a 50/50 mixture of Ford Premium Cooling System Fluid E2FZ-19549-AA (in Canada CXC-8-B) or equivalent meeting Ford specification ESE-M97B44-A and water can be added to the radiator coolant recovery reservoir.
Check coolant level in radiator coolant recovery reservoir and fill as necessary.
g. Install engine appearance cover. Tighten engine appearance cover retaining nuts to 5.2-7.2 N-m (46-64 lb-in) and retaining bolt to 9-12 N-m (80-106 lb-in).
