I need to know how to replace the timing so that the belt lines up right
Hleigh21: seeing that there was only one engine which used a timing belt in the ford ranger that I could find, I must assume it is the 2.3 liter four cylinder engine.
The cam gear has a mark which when you are facing the engine, which should be lined up with the pointer on the motor which is at about the 5:00 o'clock position. The crankshaft should be at TDC (top dead center). There is a mark on the crank pulley and you have to use the timing cover as the other reference to line up TDC. The timing belt tension is set by a spring tensioner which you let apply the tension naturally to the belt and then tighten the tensioner bolt to a maximum of 20 foot pounds.
A good rule of thumb on checking the belt tension is: at the longest span of the belt, using your thumb and forefinger, it should not twist more than 45 degrees. If if it twists more, the spring on the tensioner may be a little weak. You can make the belt a little tighter pushing on the tensioner until you have the results I have described. Avoid over tightening. This is not an interference fit motor so it will not bend valve if you make a mistake (based on the references I have). Note it is a good idea if you have over 100,000 miles, to replace the cam seal, aux drive seal and front crank seal while you are doing the timing belt. They usually start leaking around that time, not to mention the age at this point in time.
I hope I have provided adequate information. Good luck.
