If its coming from your engine, you may need a valve adjustment..
Is it a lifter ticking?
Most likely it is the exhaust manifold leaking, which is very common on this model with the V6 engine. It is usually most noticable when the engine is cold, and gets better as it warms up.
Often a knock when cold is caused by piston slap, which is pistons rocking in the cylinders until they expand in size when the engine warms up.
That depends on what is ticking, and why. Generally, a minor engine tick that suddenly goes away was caused by a clog in the oil pathways inside the engine that cleared up suddenly. If the engine generally ticks until the engine is warmed up, this suggests a clog in the engine's internal oil pathways that stays there, but as the oil warms and thins it's able to squeeze through enough to stop the engine from ticking.
Does it quit shaking when it warms up? What engine and year of Aerostar?
The preheater warms up the engine so it will start easier and in freezing weather will help to avoid freezing of the coolant.
Check for vacuum leaks.
if its a tick not a knock, its probably lifter noise. its not too terrible, once the weather warms up, i would recommend getting some thicker oil, if it fixes it, then im probably right.
A cold engine will often experience trembles due to the inefficiency of engines when not at operating temperatures. This quickly goes away as the engine warms up.
i have a 2000 dodge work van 318 engine when i start in the morning it stalls several times until it warms up then ok
Valves tapping?
