Customer Concern: Tests/Procedures: Potential Causes: Tech Tips: Loss of engine coolant, and smokes out the tailpipe. No external coolant leaks. 1. If the engine does not appear to be burning the coolant, suspect a leaking Exhaust Gas Recirculation (EGR) cooler. 2. Remove the EGR valve from the intake. Pressurize the cooling system and lift the rear end of the vehicle. Look for any coolant to puddle in the intake where the EGR mounts. If any coolant is seen, replace the EGR cooler. 3. If no leaks are seen with the EGR removed, drain the coolant level down and pressurize the cooling system. Then with a stethoscope and long hose, listen for air in the exhaust or in the intake where the EGR mounts. If present, again replace the EGR cooler. Exhaust Gas Recirculation (EGR) Cooler NOTE: refer to Ford Technical Service Bulletin (TSB) 09-8-3 for tips on addressing cooling system problems. It is generally recommended to also replace the oil cooler heat exchanger if an EGR cooler failure has occurred.

SERVICE INFORMATION A revised service procedure for the engine front cover/timing chain has been adopted for the GA16DE. It is no longer recommended to remove the cylinder head when removing the timing chain/front cover(s). Utilize the following steps when servicing the front cover, timing chain, guides or tensioner(s) PARTS INFORMATION Caution ^ After removing the timing chain, do not turn the crankshaft and camshaft separately or the valves will strike the piston heads. ^ When installing chain tensioners or other sliding parts, lubricate contacting surfaces with new engine oil. ^ Apply new engine oil to bolt threads and seat surfaces when installing the camshaft sprockets and the crankshaft pulley. ^ Do not spill engine coolant on the drive belts. ^ Please refer to the Service Manual for the correct tightening torque. Removal 1. Set # 1 piston at TDC on its compression stroke. 2. Remove the spark plug wires. 3. 4. Remove the rocker cover (see Figure 1). Remove the coolant reservoir tank with bracket and reposition it for clearance. 5. Support the engine with a suitable jack. 6. Remove cylinder head front mounting bracket. 7. Remove engine front mounting, then the engine front mounting bracket. 8. Remove cylinder head front cover. 9. Remove the upper chain tensioner (see Figure 2). 10. Wipe off the links of the upper timing chain next to the timing marks on the sprockets. Put paint marks on the timing chain, matching them with the timing marks on the cam sprockets and idler sprocket (see Figure 3) 11. Remove the four (4) front cover to cylinder head bolts. 12. Remove side and lower engine compartment splash covers. 13. Remove the accessory drive belts. 14. Remove the crankshaft pulley. 15. Drain coolant by removing the cylinder block drain plug and opening the radiator drain cock (Refer to MA section of the Service Manual). 16. Drain engine oil. 17. Remove intake manifold support of engine front side. 18. Remove power steering pump, pump bracket and tension rod. Position pump aside for clearance.
