How to remove the AIH from a heater?
Start by removing the black ground wire, and then disconnect the red wire from the heater, following that wire to the relay/solenoid. Loosen the nut holding the red wire on and remove the red wire. Be sure to leave the blue wire connected to the relay; it needs to stay. You can then remove the AIH from the intake manifold.
How does the AIH work?
The AIH is modulated by the pcm via a relay that is located next to the glow plug relay. This intake heater protrudes directly into the air stream in the cold side of the intake manifold and blocks approximately 20 percent of the intake path.
Is AIH needed in a truck?
Meaning, the AIH is rarely used, and on most vehicles, especially those in warmer climates, it is not needed. It's a pretty common practice to remove the AIH completely from the truck, freeing up some of the space in the intake tract, allowing for better airflow.
Where is the air intake heater located?
The air intake heater is located in the line that runs from the intercooler to the top of the intake manifold on the right side of the engine (le ft side if you are standing in front of the truck looking into the engine compartment). It is in the intake portion of the manifold, you will see a terminal sticking out of the manifold with a wire connected to it. That is your AIH. If you trace the wire back it will take you to the relay.#N#The reason for the AIH is to assist in heating the air during initial start up; I believe it works at or below 70 degrees. My first post explains how it works, read the blue text—that info is straight out of the shop manual. I have read more than one post where people who live in warmer climates don’t even bother, or are not in any rush to fix this problem; they don’t need the AIH to work like you would in a clod weather climate.#N#When it is cold out watch your amp meter for the first minute or so after you start you truck. You will see a large draw on the system—that is the AIH heating up. After the truck is running and warm the relay shuts the AIH off, you will see your amp meter go back to normal.
How to tell if a heater is working?
Another easy way to tell if the heater is working is to remove the air intake tube (blue hose), look down inside--you will be able to see the bottom of the heater. It almost looks like a spark plug but with coils instead of an electrode.
What is the main component of an electric heater?
The primary component common to all electrical heaters is the electrical resistor. When you turn a heater on, the electrical current that is produced heats up the nichrome wire components — better known as the heating coils — in the unit. Electrical energy is turned into heat as the current passes through the resistor.
How does a convection heater work?
The air passes over the heating elements and then is pushed out into the room — this is similar to how hair dryers work. This is also known as convection heating because the warmth is transferred through the air. Convection heaters are a good way to warm a space quickly by getting hot air to circulate around the room.
How do portable heaters save money?
There are three main ways that portable heaters will save you money: 1 You will consume only as much energy as is needed to heat the spaces in your home that are being used. During the day, if most of the family is at school or work, just turn the space heaters off or down. Use a portable heater to warm the spots where people are working, cooking or watching TV and let the heat follow you around the house. 2 Portable heaters do not require any installation. Some units can be wall-mounted, but all can be easily moved and stored when the weather warms up. This saves you money on installation costs. 3 Portable heater maintenance is an easy DIY affair. Simply follow the guidelines set out in the user manual and keep the unit clean. There is no need for expensive service calls and regular professional maintenance tasks as there is with a heat pump or steam radiator system.
