[DML] Re: Couple Questions- Coolant System & Idle

["Harold McElraft" <hmcelraft@xxxxxxx>]

For the bleeding there are several aftermarket kits. Why do you 
think you need to bleed? If the coolant is recirculating into the 
coolant bottle then look at Service Bulletin ST-09-10/82. It is a 
good idea to have the front of the car lower that the rear (like a 
curb height) to get every bit of air out.

As for the idle when cold, there are few D's that will idle 
completely stable at a cold start. Usually the colder it is the more 
likely the "hunt" for the idle speed. Basically the idle speed motor 
just can't react fast enough. Since the engine is "tuned" at 
operating temperature - as the engine gets cold sensors turn on some 
turn off the fuel pressure regulator bi-metal arm contracts, etc. In 
short, lots of things change. Continuity of components is lost. That 
is not to say that something may be out of adjustment or faulty if 
things do not stabilize after a minute or so (usually when the bi-
metal arm in the fuel pressure regulator warms up) - but, some hunt 
is perfectly normal. You may be able to get the hunt to slow by 
changing engine speed with a tap of the gas peddle.
