Has anyone used a grid heater like on the Cummins on a Toyota diesel?

Ya my 13B-T has one. Glo plugs suck. My opinion .12H-Ts and 13B-Ts have them( element heaters)

dear prado,
What is a grid heater and how does it work? Do you have a picture of it? I have a 3B engine, can i install one?
cheers

I agree. Glow plugs suck. Did you use the Cummins intake block spacer and do you manually operate? Thanks
A grid heater is an element like an electric kettle has inside or a stove. Current passes through the HEAVY GUAGE wire and turns it red hot, so it heats the air. So when you start your motor on the intake stoke the vacum sucks the HOT air and assists the combustion. Im my opinion way more efficient than glo- plugs.
Yes you can install one . I would get a complete intake setup from a13B-T and go from there. There are different voltages for 3Bs 12 or 24 depending what country you are from, ie Aussies are 12v.
There is a post on here that has a picture I cant remember right now but you can do a search.
AARON.

No the 13B-T and 12H-ts have the grid or element heater stock.
I can't think of any IDI diesels that use intake grid heaters. I'm not sure that a grid heater would do much on and IDI engine, I mean the air is being heated as it is drawn into the engine, but I'm not sure that it would be all that effective considering all the cold steel of the PC chamber. Just speculation as I am not an engineer that has extensive experience in cylinder head/combustion chamber design. In any of my old cummins 6BT powered work trucks they would start decent without pre-heat in -10/-15c, just would smoke a little more and cough once or twice. If you do it let us all know how it goes.

I find it odd that Toyota used glowplugs on the 1HDT. Other direct injected engines seem to have screens. I really don't know which work better but I do think Direct injected engines start better even when you don't use any glow system. My 3Bs would never start at 0C without glowplugs but the 13BT does it regularly (I have manual control on my BJ74).
One trick for glowplug rigs is not to fuel them too much when cranking. The fuel spray cools the glowplug.
Glowscreen = crank with foot on floor
Glowplugs = crank with slight pedal

The 1HD-FT in the 80 had one fitted for the UK market. It works on the 'Superglow' system where the 'glow' time varies depending on the coolant temp. Can stay on anything up to 2 mins after startup. Mine packed up due to a burnt out relay but made no difference to cold starting but then we don't get the real cold temps that some other markets get.
There is a picture of a 13BT glow screen in this post:

thank you prado t, well explaination. i never heard of a grid heater before.. that' s very interesting.
i will look up and see if it works.
Cheers

Don't hook it up directly to your existing glow plug controller circuit. Intake heaters typically consume a lot more current than glow plugs.
I must be missing something: I always understood on direct injected diesels there was no need to ever touch the skinny on start-up. I know that the TOYOTA manual says slight pedal for the B series.
BUT then havnt been in anything colder than -14 with the 74, I didnt even wait for the grid it fired on second rev.
Yes you will need a controller from a BJ 74 if you use the grid (element) from a 13B-T

Both my BJ74 and my Cummins respond better to hammer down when it counts (colder than -20C) After -25C they want a visit from the ether bunny or to be plugged in.
I installed a neat little heater in the intake of a small yanmar marine diesel 5 or 6 years ago, it was connected to a small res. of diesel, and the diesel would drip on the element when it was on, and put white smoke into the intake. was made by perkins, installed into a threaded bung, 1" npt or something like.
and that's about all I remember about it unfortunately.
it was pretty cheap, 30 bucks or so, made a huge difference to the start of that little diesel. it was pretty much worn out so it needed all the help it could get.

even on the coldest days -30C my 3B will start with 8 seconds of holding the glow plugs... followed by 2 or 3, 5 second bursts of glow when running to smooth idle...
I never touch the peddle when doing this... and it's never not started, until the day I left my lights on DOH!!!

that's what I'm thinking! I know they burn out once and a while and there is some related circuitry, but they work! They're easily tested, replaced and I don't think there's a better way to start an IDI diesel
