Re: AIH Delete

She started on a block-heaterless morning with a -40F windchill last winter.... Then gelled up and died. Lol... So with good working glow plugs and glow plug relay you should be just fine. Just make sure if its cold enough to use an additive... Which applies regardless.

Re: AIH Delete

These are the requirements for AIH activation on PSDs: (From Bob Riley's DieselSite web page)

FAQ: What is the real purpose of the intake heater, and when does Ford say it will operate normally?

"To reduce white smoke during long idle periods at low ambient temperatures, the PCM will activate the intake air heater. Specific conditions must be present before the heater is activated: "

ambient temperature must be below 0 deg C (32 deg F)
engine oil temperature must be below 55 deg C (131 deg F)
vehicle power must be between 11.8 and 15 volts
parking brake must be applied on manual transmission vehicles
the transmission must be on park or neutral on automatic transmission vehicles
glow plugs must be off

It is a very specific set of circumstances. You wont miss it. It will throw a soft code, but wont hurt anything.
