1HDFT air intake heater

[landcruiser 53]

1hdft air intake heater in the intake manifold/If the heater were to be removed wouldnt you have to give it more fuel because it also acts as a restriction. has any body removed it and done any modifications??Your help would be appreciated

[lokka]

Ive also woundered WTF it did and what would happen if it was deleeted any ideas would be good

I've had mine removed since installing a 1HD-FT into my 70 series a couple of years ago with no ill effect.

Any increase in air flow won't affect performance as a diesel will only requires enough air to burn the added fuel, any excess passes through to the exhaust.

Cheers

I pulled it out of the FTE in my 80 series and it doesn't seem to have affected the computer at all or the running. Cold morning starts also don't seem to be a problem.

Yep ok fester but have you gained anything from removing it better or quicker spool up is yours auto or man ???

What little restriction the intake heater provides (if any) will be more than compensated/outweighed by things such as pump and injector wear. I doubt you'll see any performance gains, apart from less current draw at startup.

the air intake heater only works in real cold weather. heats up the incoming air on start up and I was told you can remove it without any problems arising. The only thing I had noticed was that I was using a little more fuel that is why I thought that you would have to adjust the fuel

The safari intercooler kit does away with it....it also directs any oil coming through right down no3 and 4 intakes, so removing it has a few benefits....less wear and tear on alt and battery and belts, less chance of oil deposits turning to carbon and holding valves open in 3,4 (happened to mine when things went pear shaped) better flow around the manifold to 1,2 and 5,6. Down side is the puff of smoke when started up.

That is the best bit of info ive heard so far as old mans has just developed a slight miss and carbon deposits in the valve area are the likely cause so out with the heater and in with an oil catch can and a revised PCV set up me thinks and a dose of FTC decarbonizer

Whats the best way to remove it from the system?
Just pull it out, or
Knock the element out of the housing and put the housing back.

I havn't realy looked into it but obviously you need to disconnect the wire or remove a relay or something electrical so it doesnt short out.

Do you then get a warning light on the dash?

[dow50r]

The element can be removed from the housing and then the housing replaced...the hole in the side where electrical element comes through can be tapped and used as a boost offtake or plugged with 1/8 bsp plug.
I did away with it altogether and made up a manifold to 3 inch hose adapter for an intercooler setup.

Did inter cooling it make much difference as that mite be on the cards for the next upgrade for old mans a top mount or one of them water to air barell types ..

As for the power to it on the pass side inner guard theres a solinoid type relay that sends power to the heater would be simple to un do the wire from it and maby use the solinoid for somthing else it has a white/clear plastic cover over it and is fairly chunky makes a good solid thump when turned on as i found it while sorting an elec gremlin in old mans truck

I didn't expect any magical performance gain but did it based on any restriction was a bad restriction and in our climate I didn't need the heater. It may have made a difference but my "seat of the pants dyno" couldn't feel anything. Being an FTE mine is chipped up anyway, however I have no discernable smoke at start up or under load.

I pulled the element out but left the wiring connected as it is insulated through the mounting and without the completed circuit it does nothing and this was quicker and easier than bothering to find something to plug the hole.

In the FTE the heater is actaully just off the turbo outlet pipe rather than on the inlet manifold like the FT. What I see in mine is the void that is left in the chamber could actually be bad for airflow in that is allows a pocket for it to expand and slow down. Minor I know but in an ideal world when I get time I'd prefer to remove the housing altogether and replace it with a section of pipe or hose. Probably not the same issue on the FT given the closeness to the actual inlet manifold. The FTE runs a longer inlet tract to the FT also as it runs around the back of the head as the hump is in the middle.
