1HZ Troopy rear heater delete

[woytovich]

I know there's a thread on here with some info but it's not very detailed...

Looking for some guidance to remove the rear heater and related piping on my 1995 HZJ75 Troopy. I'd like to do it as cleanly as possible and I'm hoping for some info from someone that has done this on a 1HZ.
I'm not worried about removing the heater itself - I'm looking for help on the engine side... Can I/should I just loop the in and out with a hose to bypass before the hard lines (the red arrowed lines)? Is it "better" to cap off the in and out at the engine (?) and if so, where exactly.

Pictures please.

I actually wanted to obtain all these parts and install the rear heater! rare and unavailable parts nowadays

it should be as easy as obtaining the non-rear heater hoses. go through the catalogue and find the parts with both versions and order the normal ones for just the front heater

I can sell/send you what I pull out! Can you send pictures of what yours looks like without the rear heater pipes?. OR: send me your VIN-verified model number so I can look on PartSouq
My VIN is JT1VHZJ7509000380 which is a

  I'm not SURE what to get from this... I see the w/RR at the bottom vs without at the top.

THANK YOU SIR!

Will it be "obvious" what to remove and replace with these?

THAK YOU SIR!

Yes.

 

[DamoPeru]

in fact, if your front heater is installed, you only need the two yellow ones, though you'd want to get all three so they have the same life span going forward. the third pink one you should have installed already going from the control valve into the firewall

I'd be interested in that, but I'm in Peru, so the parts would have to be refurbished to practically brand new condition and packed as if they were new to get past (trick) customs... it's illegal for me to import secondhand parts and I've been stung before with people sending me stuff that looked worn or was dirty

Thanks for for the info... I will look at this again tonight. And I'll look at the "newness" condition of the heater. (the hard lines to the rear heater are trash as you might expect)

thinking about it, it would probably actually be pretty easy to take the main heater/blower unit to a radiator shop and have them completely refurbish it with a lick of paint. Technically that wouldn't be illegal for me as its no longer just a 'used part'. I've never actually seen it in the flesh, but I'm assuming the heater and blower are one unit, complete with controls. I'd say PM me with the details, but you may as well post any photos here so everyone can see.

I would love the hard lines for neatness, even just the parts to get me out of the engine bay. they could be re-galvanized, but if you don't have someone local to do that it would be getting into PITA territory

the yellow replaces the pink :

again, yellow replaces pink:

Get rid of everything on the last picture. None of it is needed.

Everything else is going to be self-explanatory.

What are both your thoughts on using generic heater hose rather than the OEM Toyota parts?

 

[woytovich]

For the record, this is what I have now.

You may have a water pound in bung under the intake manifold that points back snd feeds the rear heater.

you may need a freeze plug to block it off.

You also need intake gaskets. Maybe a good time to pull bung and replace w freeze plug.

 

[woytovich]

"intake gaskets"? As in air intake? Do I should I be pulling the air intake to do this? Is there not a "simple" way to just bypass the rear heater lines that run to the back... connect the in and out that currently go to the 2 metal rear heater pipes?

save yourself the headache of making straight hose bend around hot engine parts, bearing in mind you'll loose all your coolant on the fly if any of them fail. the hose on the LH side is particularly difficult with a couple of 90 degree hard turns. the RH side is less difficult, it just makes a nice arc.

he needs it, its the same outlet that feeds the front heater. regardless of whether you have front or front/rear, there is still only one outlet and one inlet, both shared for the front/rear setup.

Stop being cheap, Mark. Buy the correct parts and do this correctly.
