Valve Springs: Removal
WARNING: This page is about a different car, the 2007 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in the crankshaft pulley procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if you loosen the pulley bolt. Before any repair requiring loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in place by the special tools, otherwise severe engine damage can occur.
- Remove the valve tappets. For additional information, refer to Valve Tappets in this article.
- Using the special tools, apply compressed air to the cylinder.
- Using the special tools, compress the valve springs and remove the valve spring retainer keys using some grease and a small screwdriver.
- Remove the valve spring retainers and the valve springs.
WARNING:
Always wear eye protection when servicing a vehicle. Failure to follow this instruction may result in serious personal injury.
CAUTION:
Use compressed air at 7 to 10 bars (100-150 psi). Do not disconnect the compressed air from the cylinder until the valve spring, valve spring retainer and valve spring retainer keys are installed, or the valve can fall into the cylinder.
NOTE:
Place all parts in order to one side.
