Daihatsu Charade G102 91 Need to change thermostat though appears hose from top of radiator runs to housing and bolts are hidden under distributor assemble. Any step by step help would be appreciated

If you have to pull the distributor, take off the cap and mark on the dist. housing the position of the rotor, exactly where it is pointing to. Also mark the dist. housing relative to the engine block, or the adjusting bolt or nut, so when returned to its place in the block, the distributor is in the same exact position. Do not rotate the crankshaft with the distributor out, or you will have to re-time it.

To re-time the engine, you have to put the #1 cylinder at Top Dead Center of the compression stroke, then drop in the distributor with the rotor pointing to the #1 cylinder plug wire tower. Now it is in time at zero degrees. Get it running and warmed up, then use a timing light to set it at the BTDC specification.

To find the compression stroke of #1, pull the #1 spark plug and turn the engine clockwise with a socket on the crank pulley bolt. Hold your finger over the plug hole. When you feel pressure build up, you are on the compression stroke (there is an exhaust stroke and a compression stroke-when the piston is rising on the compression stroke, you will feel the pressure. There is no pressure build-up on the exhaust stroke.) As soon as you feel the pressure, look at the crank pulley and continue turning the engine clockwise until the notch or mark on the pulley is lined up with the zero degrees mark on the pointer scale. The #1 piston is now at top dead center. Now drop in the dist. with the rotor pointing to #1 spark plug tower. However if the engine was not disturbed while the dist. was out, you don't have to retime it if you marked both the rotor position, and the dist. housing relative to the block where it sits.
