How to: Replace EVERY Coolant Hose on FZJ80 80-Series Toyota Land Cruiser, feat. Pesky Heater Hose

Today I’ll show how to replace all the coolant hoses on the 1fz-fe engine of the 80 series Land Cruiser including the dreaded pesky heater hose (PHH.)
I'll also show how to bypass the rear heater, whose metal lines often rust and can't be replaced without removing the entire transmission.

Probably the best 80 series video I've seen on youtube!! Thanks!!

[@coltenphoto]

Truly, truly, thank you for this. The part numbers are greatly appreciated.

[@6thGearGarage]

Glad it was helpful!

[@yotersmitt]

This vid was just what I needed. Thanks much for putting it together. Very helpful.

[@6thGearGarage]

Glad to see it helped someone else!!

[@carter18622]

Couldn’t have posted at a better time! I’ve got all this sitting in my wits end cart right now.

[@6thGearGarage]

That’s where I got mine from as well 👍

[@Ghostrider-71]

Great video. Great explanation especially for nomenclature of the various hoses and attachement points. I will need to do this for my 1-HDT at some point.

[@charliecoco2115]

You have a TV / Movie 'voiceover' voice. Easy on the ear.

[@6thGearGarage]

Well thanks! Good to know I may have a backup career if this youtube thing doesn’t work out 😁

[@NKPGarage]

Love the detailed video. Very nice work brother!!

[@eurokayf]

Good job. Very detailed. Love that front brush guard setup.

[@6thGearGarage]

Thank you. The brush guard is a rare OEM option on the JDM 80 Series. My 80 has a lot of rare options, here's a video I made showing them all kzbin.info/www/bejne/l6ObeqKmaKlqqdE

Great video! 😊

[@kurtchristopher7392]

Great videos! Thanks for taking the time to make them.

[@6thGearGarage]

Thanks for watching, glad to see they are helping people.

[@NigelNaughton]

The best thing about changing all the hoses is that soon after your head gasket will blow and all that work will have been done in vain 😜. There are specific types of hose clamp pliers that work great with those clamps. You squeeze them and they lock so the clamp is open and then you can move it around very easily. Cool vid.

[@6thGearGarage]

Hahaha that would be my worst nightmare! I'll check out those hose clamp pliers, thanks!

[@KiyaWarrior]

Great video. I did all of this last year myself before I saw your guide, however you did just help me with something else @ 25:23.... The mechanic that I took it to a few years ago did so bad and left so many things loose / un-plugged and you helped me find another part. Ugh, thank you but what a nightmare that was. I have done all of the maintenance myself ever since. Keep up the great vids man.

[@6thGearGarage]

Great to hear!

[@Henray316]

Thanks for the video. I would throw some fresh belts on while you had it open up front

[@6thGearGarage]

They were supposedly replaced before I Bought it, but you’re right it would have been the ideal time. I considered replacing the radiator as well while the fan and shroud were out but they’re not exactly cheap for a nice one.

[@chairmanmao3885]

Awww yesss🎉

[@retro_88yota]

I have learned the hard way not to crush the heater hose tubes. I tried to flush a heater core in a 87 toyota pickup and crushed that line. I opted to replace the heater core and learned that those tubes dont come with the heater core and they are obsolete.

[@6thGearGarage]

I had a heater core for a pickup with a bent tube that I was able to heat up and bend back to round with some sockets, similar to the way I repaired a bent radiator neck: kzbin.info/www/bejne/nJLVgYuKpZataLc

[@retro_88yota]

@@6thGearGarage I have fixed them too but it sucks lol

[@richdevito78]

What did u do with the electric switch for rear heater?

[@6thGearGarage]

I left it as-is, in case I ever get around to replacing those rear lines.

[@drewfleming7065]

WOW...Your right....what was Toyota thinking????? I'll stick with my 22R. Toyota got it right with it....

[@6thGearGarage]

It doesn't get much simpler than a 22r! Great motors to wrench on!

[@drewfleming7065]

@@6thGearGarage Dang thing only weights 385lbs....4 people can pull one out with a 4x4 and some rope....Your vid would be GREAT help for someone with a 80 series....

6th Gear Garage if you need any help with the hose let me know i live in australia

[@6thGearGarage]

Thanks mate!

[@GrandmasMallCrawler]

just reverse in a drive thru

[@6thGearGarage]

I did once at an ATM :)

[@sommyerroa]

Those hose in the back are worse when the steering wheel is at the left side 😒

[@6thGearGarage]

I probably wouldn't have even been able to film the video if the steering was on the left hand side. There's just not much room to see or do anything.

[@FIVEVEEZEE]

Pesky heater hose and throttle body hose isn’t even bad on a RHD 😂. If you had a LHD you would not be able to film half of this. The PHH is somewhat visible, and the throttle body hose has to be removed and installed by feel. Hardest part of the PHH is the bolt of the back of the head.

[@6thGearGarage]

That bolt was the worst - I left it out.

[@tbassiii]

Really? I thought it was easy, I’m having a hard time figuring out how to remove the damn hose! Lol

[@FIVEVEEZEE]

@@tbassiii remove the spring clamp from the block side. Needle noses will work best in my experience. After that I made some cuts in the hose. It pulled off easily after that. You remove the pipe assembly with the hose still attached to it through the wheel well.

[@tbassiii]

@@FIVEVEEZEE ah that’s what I was wondering. You can see it through the wheel well with the wheel off? I was about to pull the starter haha

[@FIVEVEEZEE]

@@tbassiii Yes. I don’t think removing the starter will make a difference. It’s not completely obvious. Pretty buried in there
