That's a beautiful piece of work. Nice job!
That's a beautiful piece of work. Nice job!
been away from home a while. managed to get some time on the cooling bits. could not find any beam clamps locally so i made some up. shroud is ready to fit and made a simple m16 x 1.5 adaptor for the 1/8npt durite sensor i will be using for cyl head temp gauge (stock gauge is no good) un linear response. im going for a painless performance F5 dual fan controller, not heard so many bad things about them, seems like it'l work! . just got to wire it all in .
regualr steel beam clamps will work if you can find em
small adaptor making durite sender as long as possible
sensor location for fan control is at the moment bottom inlet to rad
That's an impressive looking fan unit (big motor and massive blade pitch). I see from a previous post they are 2 x 9" 755cfm 7.5A spal suckers. I will be interested to hear about performance. Where did you get them? Tim
kool it , paso robles CA. pn: VA02/AP70 -LL40 . i was hoping the shroud would make up for the compact fans, should use 100% of rad instead of 43%. when your guessing a design just squeeze what ya can! if it runs50% duty it'll be excellent, wait and see i guessOriginally Posted by timsrv
. couldnt find any on the shelf over here
Just discovered the diesel thread... nice work. I am a new owner of one of these. 89 master ace surf. I imported it from BC to Washington state. Working on getting a couple new break parts in and the cooling system before I can put some miles on it and see what else she needs.
good luck with it, plenty of road testing to be had with Toyota that's for sure :-)
finally, i got 240km munched today. Passed the big test last week, still weeping on a rear brake cylinder (drum) and needs tracking, but good to go.
its a hoot! like driving a motorized see saw.. bobs up and down under the 1700 kg weight, panoramic view, slow as f**k bieng the auto diesel, but its got character and its got gadgets and 4wd , whats not to love.
now to make the interior a little less purple , and get some running water inside, make it more camping equipped
like to report back so far the Painless F5 seems fairly sensible,
it ramps up the first fan for a few seconds, then ramps in the second, at 50% duty set at your lowest setting i.e 160f, then your highest setting (the other POT) for 100% duty will be set at your higher chosen temp by dialling in the pot perhaps 200f .. the controller creates a linear rise of fan speed per degree set point between low and high from 50-100% duty on the fans.
reading of coolant measuring the head temp using the durite, the sender is gauging just below the inlet manifold, reading is stable at 194 slow , 203 fast moving, but it seems fairly unconnected with the fans on and off cycle i am seeing (alot). really it would be ideal to get not only a sender with the kit, but also a LCD readout so you can actually see what your setting the F5 to. is there any easy way to measure the coolant temps while running without installing another gauge?

Wow Adamh,
not only are your mechanical skills impressive but your video/music editing was very enjoyable
thank you for sharing those ideas that I can only enjoy vicariously thru your skills!
On a side note if your ever able to get a hold of some rear taillight assemblies I could totally use a set.
Nice documentation and thank you for sharing!!
Awesome post and video!!! Thanks for posting.Tim
looking for a tail light myself, i have a cracked one, seems like they are quite rare . i have seen them with orange lenses up top but not clear ones which is what is on the other side of my van.Wow Adamh,

i would like to report back another successful 150 mile drive.
ambient temps was 51F / 11C
speed varied upto 60mph, it was also raining on and off
running temp is a constant 194-198 deg F (90-92deg c) peaking once i think at 201f (94c) after a long slow climb on a hill. (according to gauge)
i have seen it run 198-203 but on a much hotter day with ambient temperature 77f (25degc).
it was raining today so i got free charge cooling!.
boost is nominally 2-5 psi when just coasting about, when freewheeling its zero of course.
when foot is down i am showing only 6psi max.
The gauge i am using is fairly low cost so i expect a psi or two either way tolerance.
Given the fact it a low HP engine (85ps) and 3500lb weight constantly on boost i think it would be advantageous to intercool it, wether i get the time or not is another factor, it certainly has the room where the stock air filter fits to squeeze in a cooler and fan and a drop the air filter lower
i have not yet dialled in my F5 fan controller properly but it seems to work good, i set the ON temperature fairly low on the POT , so it comes on at a low temperature , i am unsure what the actual temperature is but the way i see it as soon as the thermostat opens at 180f the fans should come on so the 'low' on potentiometer should be lower than the thermostat.
i dont know at which road speed the fans make no difference, i think i'll wire in a dash led so i can have a look at the fan habits at higher speeds.
there is a speed signal cut off for the fans which picks up off the vehicles speed signal wire so if i can find the VSS wire i may use it later.
its a ball driving these vans
blacked out the bus today, 80% on rear its slightly lighter in 1st person. its a camper so when its full of stuff and we are inside the stuff is not so visible. slightly lighter in 1st person.

Hey hopefully you're still active on these forums. May I ask what that large box is in front of your center console? Is that the ice box? I ask this because I have been looking at making a custom subwoofer box with cup holders in the same position and now that I see this box, it's perfect! Now I just need to find one.
That is in fact an icebox. Actually, none US spec vans usually got a hot/cold box while the US vans just got the optional icebox.
