and the other side

I did add rubber gromets in them through frame holes

Stopping power!

Re: My Dusty 71 GMCe Electruck
 

That's a mighty tight bend in that hose. Is the spindle at the end of turn travel?

Re: My Dusty 71 GMCe Electruck
 

I hear you Steeveedee and was thinking of swapping for the C20 hosers but word on the street is they might be the same length

Re: My Dusty 71 GMCe Electruck
 

so I had to scroll up in my own thread way up to post #72 to see what radiator I had and as it turns out it is a generic aftermarket Spectra Premium part #CU369 one that fits the truck but is not specifically for this truck, so it doesn't quite fit on the bottom, it is too thick if you will, being 2 core and all

so I done did some research and learned that a Squarebody aka 1973 and up single core will fit perfectly and the reason I tell you this is that it can be had for half the price of an exact specific 67-72 one

Murray Radiator part # 433161 $200 bones and you can get one like it for $120 on Rock Auto I just didn't have the patience to wait on it to arrive so I went to Oh' Really s

Re: My Dusty 71 GMCe Electruck
 

Good info TY

Re: My Dusty 71 GMCe Electruck
 

so now we have reached the plumbing, heater hose size, coupler, adapter, reducer hell portion of the build, you see we in America like to design our radiators with the largest inlets and outlets known to men and women, and the electrical components (inverters, dc-dc converters, chargers, water pumpulators, and transmissionisters) all like to use small ones, more on this later

essentially what we face is that we can no longer plumb with radiator hoses ( yes 1-3/4" or 1-1/2 or my personal favorite 1-5/16" that's a nice and even 33 millimeter for you non Standardizer type) but instead must plumb with heater core hoses ( 3/4" and or 5/8" )

Re: My Dusty 71 GMCe Electruck
 

Tezla electric water pump (yes with a "z") uses a 3/4" standard American heater hose

Re: My Dusty 71 GMCe Electruck
 

it needs to attach to the radiator outlet which is lets just say way bigger ( 1-9/16ths for those of you keeping track at home)

Re: My Dusty 71 GMCe Electruck
 

now the fun continues as the 3/4" hose from the Tezla water pump has to now mate with the 5/8" Lexus inverter inlet, joy

the inverter is arguably the most important metal box in the entire jigsaw puzzle as it convert DC direct current stored in the BMW batteries into AC alternating current which the Lexus motors consume inside of that unicorn of a transmission

Re: My Dusty 71 GMCe Electruck
 

so back to fighting with that Honda CRV electric brake iBooster, the darn thing pulsates when the pedal is fully down, I just don't get it, I know it was designed to work with only disc brakes so maybe there aint enough flow

but I tried capping off the rear brake line at the master cylinder and pressing the pedal to only engage the front disc brakes, and the pedal still wiggles when fully down to the floor

I even tried by capping off both outlet ports on the master cylinder, still no dice, is it air?

Re: My Dusty 71 GMCe Electruck
 

Did I miss how you plan on heat defrost etc and cooling transmission just interested on how your planning that if it’s in a post pardon me please

Re: My Dusty 71 GMCe Electruck
 

excellent questions

no heat / defrost in Phase I of the implementation, I live in California (pronounced: Spring, Summer, Fall, repeat) however if I do decide to add heat it will be via an electric heater such as the one from the Chevy Volt

as far as cooling the transmission I am going for the belt and suspenders solution, first like any traditional automatic transmission it is plumbed to the radiator's transmission inner cooler that is integrated into the regular dime a dozen Chevy type radiator, then in addition to cooling the transmission fluid this transmission has water cooling built in, so those hoses also run to the regular car radiator (same one) but to the regular water inlets and outlets

all this gets recirculated via a Tesla Model S electric water pump

hope that hels

and this is what a $150 bones worth of hose reducers, couplers, and thing majigs look like

Re: My Dusty 71 GMCe Electruck
 

some trial fitment going on here, I do plan on cutting the 90° elbow shorter to bring the hose closer to the Inverter allowing me to use a hose clamp off of it to secure it so it's not all up in space like this (by the way that's a Tesla Model S water pompulator)

the Inverter is a metal box that changes DC Direct Current stored in the BMW batteries to AC Alternating Current consumed by the Lexus motors inside the transmission

Re: My Dusty 71 GMCe Electruck
 

same on this radiator inlet hose, this is coming from the passenger side of the transmission and I hate that it has to run across the engine bay under the battery pack, wish my inlets and outlets on the radiator were on opposite sides (how could Genereal Motors not envision this back in 1967?)


this 90° downward elbow will also be shortened and brong over closer to nearly hug the radiator, this again is just some expensive brain storming

this hose will eventually not come out of the battery pack but run in front of it closer to the radiator

Re: My Dusty 71 GMCe Electruck
 

yup, so I tried to cheap out on one adapter and it bit me, here I was trying to connect a 5/8 water pump hose to a 7/8-1 1/2" radiator reducer and no dice, so what you have to do is go 5/8 - 1" reducer to a 1"-1 1/2" reducer to the radiator, oh well this gives me a chance to order a 45° reducer instead of the straight one so there's that

Re: My Dusty 71 GMCe Electruck
 

I see a future in the plumbing industry for you

Re: My Dusty 71 GMCe Electruck
 

ha, ha yup, that reminds me the proper radiator lower metal support brackets and rubbulators showed up

Re: My Dusty 71 GMCe Electruck
 

bump for you! any updates?

Re: My Dusty 71 GMCe Electruck
 

super kind of you

thinking about ditching the Gen 1 iBooster in favor of the Gen 2 ?

Re: My Dusty 71 GMCe Electruck
 

cool work. have you considered a electric power steering pump to run hydraulic hydroboost style brakes? if that is an option just would have to look at power demand that way?

keep it up bud awesome work!!!!

Re: My Dusty 71 GMCe Electruck
 

Thanks Sean the EV Community is graduating from electric power steering pumps on the account of them being noisier than the entire electric vehicle and adopting actual electric steering assists from the Prius, please take a gander at my video series on the topic here:

Re: My Dusty 71 GMCe Electruck
 

Have you been enjoying a nice bowl of slackerjacks? its a new year and we need a new update.

With all seriousness I hope all is well with you and your family!!

Re: My Dusty 71 GMCe Electruck
 

hope you are well Happy New Year

Re: My Dusty 71 GMCe Electruck
 

bump for an update....

Re: My Dusty 71 GMCe Electruck
 

Went through Sacramento a week ago, should have checked out your project:)

Re: My Dusty 71 GMCe Electruck
 

yeah The Greg has a major case of lazyjaitus

Re: My Dusty 71 GMCe Electruck
 

good to see you post something!

Re: My Dusty 71 GMCe Electruck
 

Id like to find a budget minded "kit" to do something like this. I dont need a truck to be a world beater performance wise. And I dont need to get 400 miles on a charge. But I do think 200 would be nice because some of the places I go to see family etc would be close to 200 miles round trip. Would be nice not to worry about charging stops.

I know GM is working on having a kit but that would hardly be budget minded. Im not smart enough to do all the engineering you are doing. But I can mount stuff up, make brackets, run wire, that kind of thing.

I hope you get it on the road soon as your lazyjaitus clears up. Fun watching your build and twisted sense of humor.

Re: My Dusty 71 GMCe Electruck
 

thank you so much, just dropping some replies to say I appreciate you all for following along

Re: My Dusty 71 GMCe Electruck
 

well shiet, people are actually following this debacle? who knew!

Re: My Dusty 71 GMCe Electruck
 

yeah you should have, I have allowed strays into my house from the forum before, my wife asked one night "what if he is a serial killer" and I asked the guy that and he said, man I wish but I'm just too busy and that takes a real commitment, we all had a great laff

Re: My Dusty 71 GMCe Electruck
 

Captain's Log Truck Date 3,872

been a long harsh winter here in Northern California, temperatures plummeted well below 70° F and I aint one for wrenchin in my winter shorts

The plan is to pick it up again next month aka March Madness Part II

in the meantime The Greg has gone on winter hiatus in the past so he would like to distract you with his prior project here: A '54 named Busty - LS Swap !!!

if that build is what brought your loyal butt here in the first place you can geek out on the following DIY Electric Car forum: 1971 GMCe Lexus GS450H BMW 530e Tesla Model S powered Electruck and see if you can spot the guy who loves to give me craapp for no reason

those of you who rather sit back and watch some videos and catch up that way, there is the Good Enuff Garage You Tube channel guaranteed to cure your insomnia

if I wasn't in my lazy season I might could post some actual related play lists but these hot wings aint gonna eat themselves

so honestly thank you so much for following along we will be back, bad jokes and even worse craftsmanship I promise

Re: My Dusty 71 GMCe Electruck
 

a lot of us get worried when all of a sudden there is NOTHIN....so the next time you can't find your NorCal winter shorts just give us a heads up and we will all breath a sigh of relief .....See you @ march elecmadness:devil:

Re: My Dusty 71 GMCe Electruck
 

thanks, nice to know someone is out there willing to do a wellness check, and some of you will get this (two for safety)

Re: My Dusty 71 GMCe Electruck
 

Lol .love it that’s like a high wire act with no net

Re: My Dusty 71 GMCe Electruck
 

why I haven't been wrenchin'

looks like California forgot to pay our heatin' bill

Re: My Dusty 71 GMCe Electruck
 

i think '420' is the reason.

Re: My Dusty 71 GMCe Electruck
