My dad never changed transmission fluid 1st gen 160k miles

Everything in there is silicone.....

except for the wierd squiggly one from the heater supply hose to egr valve.....that one I left black oem...


If any of those bust going down the road even tho they're small.....you'd be walking....


The blue allows to easily see any cracks/flaws as they age...

Prices have sky rocketed on silicone stuff last couple years......sooo, not everyone's cup of tea.....

those 3 pretty blue heater hoses use to be in the $70 range.......now they're almost $150....HTP...

 

I was thinking about silicone hoses when its time to do the hose replacement. But originally thought of just going to black like original hoses. Your choice of blue makes it so much easier to identify and follow.

Its mentioned that silicone is more permeable than rubber and can allow small amounts or coolant to escape over time. Have you ever noticed this?

The only things I have use plain silicone tubing so far is to replace the vent tube on the transfer case motor which has been shown to dry out and crack and allow water inside and when I relocated the vent from the rear axle up to the tail light area.

And ouch yes. Just the upper and lower rad hose in silicone are $200 CDN. That would be 4X more than standard.

The question was asked on how often things like rad hoses should be replaced. I have seen numbers like 4-6 years up to 15. I only replaced one set on my 10 year old dodge caravan and only because the brass/copper rad was so corroded that it had to be replaced and did them at the same time. I have never had one burst or fail on me so far but don't take that as a recommendation. Has anyone in their experience had hoses fail on them?

With the original poster and his 2002 I think at 22 years I would do it if it was mine. Excluding coolant he could do all the hoses in standard rubber for under $100

 

The silicon vacuum hoses are permeable and shouldn’t be used for PCV or coolant lines. You need a silicone hose with an interior liner like the HPS hoses for any coolant or oil.
The problems happen when someone buys a big silicone kit for their vacuum lines, but then also replaces the PCV hose and IACV coolant lines with them.

I did it as well, replaced all my vacuum lines with this kit:

$40 Upgr8 Universal 4mm/6mm/8mm/12mm Inner Diameter High Performance Silicone Vacuum Hose Kit (Blue)

https://www.amazon.com/dp/B00BQ0SDCU
But I did the pcv hose without knowing, and within a couple of days it was seeping oil straight through the hose.

 

Thats probably why those HTP heater hoses are so expensive....
they're not just silicone....they have a liner....
makes me wonder what the oem rubber ones cost...probably not cheap either...

I would never buy the two main radiator hoses in silicone......they may not even last as long as oem or gates....

I just get the gates from Orielly's........the radiator's top hot one I would replace every 5 yrs.......kinda pricey $28ish...

All non lined silicone can only be used for vac lines....

Any fluid ones need to be braided and have a liner....

And the pcv or any vent line must be fuel resistant.......pure silicone will just swell and soften.....and dang sure cant use butyl......I used snow mobile 5/16" clear blue fuel line for this one........$8 for 10'....


Replacing fluid lines should be like LBJ's.....worth the effort...
especially the braided ones..

 

Really the best bang for your engine.....
....is fresh coolant.......7yr coolant is a joke.....

the additives dont last that long, and thats the important thing...

How long.......I ditch the asian......and use Peak 10x...
I change it every 3 to 4 yrs........best $12 you can spend...

Of course that was after multiple flushes......
the red stuff is coating everything in the engine......and does not give up the ghost easy...
even with hot water....takes over a dozen flushes....

the asian red coolant protects the aluminum by glazing it....
....cut open one of the old radiators.....its very evident.


here's 6mo old asian...
Toyota asian coolant fail..... (youtube.com)










Who ever came up with that stuff.....should be shot

whats next.....rusty scalpels

 

I’d wished i knew about the Amazon kit Time posted b4 I did mine
I went to several old school hardware stores

Hi,

I have been trying to figure out how much fluid the power steering needs. I need to replace the power steering fluid. I tried to find it in manual specs online. I could not find it. The power steering cap says dexron II

Does anyone know how much power steering fluid is needed for a drain and fill? Can i use any dexron II ATF fluid?


It is for a 2002 Toyota Tacoma prerunner SR5 2.7L


Thank you for your help!

 

Dexron II atf is Dexron II. Dont know if they even make the II version anymore. Was superseded by III and now IV

If you have 1 quart that should be more than sufficient. I use this in my power steering. BUt lots of choices out there

https://www.mobil.ca/en-ca/lubrican...cle-lubricants/products/mobil-1-synthetic-atf

Recommended for applications requiring GM DEXRON II

 

Hi, i found power starring ATF fluid at O'Reilly autoparts at $6.99 for 32oz, but it says GM cars and I found a Prestone power steering for Asian cars at $12.99 for 12 oz. They all seem the same, but just marketing to confuse DIY self repair people.

Are all dexron II and III the same for the purpose of the power steering? Do I need a specific kind of power steering fluid. I'd hate to damage the power steering.

Is synthetic better than non synthetic dexron? Does it last longer than the 50,000 miles of standard dexron III?


Thank you for your help,

 

I made a typo , its Dexron VI not IV (not sure why they skipped IV and V)

Don't over complicate this. You can use Dexron II,III,VI. They are backwards compatible. Just get one of those.
Its must say Dexron on the bottle.If you can't find II use III. If you cant find III use VI.

Dexron was originally designed as an ATF but has been used in PS and even manual transmissions.

https://www.valvolineglobal.com/en/dexron-vi-atf/

It’s also fully back-serviceable, so it can be used wherever Dexron-II and/or Dexron-III are recommended and is specifically recommended for Dexron-VI, Dexron-II, Dexron-III


https://www.mobil.com/en/lubricants...s/our-products/products/mobil-1-synthetic-atf

This product is recommended for use in applications requiring:

GMDEXRON

GMDEXRON II

GM DEXRON IID

GMDEXRON IIE

GM DEXRON IIiG

GM DEXRON IIIH


Some PS fluids are mineral oil based so dont just go by a bottle that says PS Fluid.

 

Hello, hopefully i don't sound redundant or annoying here. Unjust have not come across these situations before Now. I found a bottle of penzoil dexron II.

It is unopened and has sat in a shelf. The man UNFORTUNATELY died last may and I have taken over the car maintenance for his car now owned by his widow who is my in-law. I ignorantly assumed people did what I do and keep detailed records of maintenance. ‍


Thanks for any help you guys can provide.

 

That will do it. And when that runs out you now know you can substitute one of the later version of Dexron.
There are two ways to replace the fluid. Some just use a Turkey Baster to draw the old fluid out of the reservoir and add some fresh. Then run / shut off and repeat.
My method is more involved but does a complete fluid replacement.
I block of the return port on the PS reservoir (brassy looking band clamp lower left in pic is where it enters) I use the red silicone block off plugs show below. Have them in different sizes an colors and use them to plug vacuum ports and even cover up exposed bolt thread to prevent corrosion.
Then attach the cheap 12 volt pump to the return line and put pump output line in a container.
When i turn on the pump it draws the fluid from reservoir all the way thru the PS system , thru the pump and out. Maybe 10 minutes in total.
I just keep adding fresh PS fluid until what comes out on the pump end is fresh.

The can shaped object is a Magnefine PS filter I added

.

 

You can do it without the pump.......just jack up the front end...

pull the return line to shoot in a bucket....plug where that hose went into the reservoir...

Run the steering wheel back and forth with engine off.

That will pump it out slow enough so you can slowly add more to reservoir to keep it topped off.

piece of cake.......


Same deal.....takes 15 minutes.

Me not special......I just watched the different vids online...


Now mines all flushed......I just take that pump once or twice a year and empty and refill the reservoir......gives litte less than a 20% change each time..
so over 3 or 4 yrs it completely turns over.....fluid is always clear now...

 

The tranny flushes is where that pump is like sliced bread.......
makes that a lot easier......

one of the best $17 I ever spent.........I've used the dogshit out of that thing for all kinds of things, no kidding.


you either need that pump or two people to do a righteous tranny flush....
so you dont let it run dry....


And O' scotty says....save the old tranny fluid......just in case....if its way over due.....

 

Hi, I saw this method on YouTube with a simple hand pump. Similar method and idea. Simple hand pump. I was going to get cheaper one in description from Amazon. Not the one in video used.

The pump is built into the steering rack......it works great!!!

just got to get the tires off the ground....

 

Here you are.......its really getting hard to find the un-insane


How to FLUSH Power Steering Fluid (youtube.com)

@ the 2:00 min mark...


This is how I did mine.... 10min job after you rig the hoses/plug and catch can is set...


The other 99 people do it the hard way.....beats all shit....

maybe they're just scared......trucks are heavy.....scary...


maybe I'm just too easy



and sure if you already have the 12v pump then use it......however it does move pretty fast......you're either fighting to keep up with it or sucking air all the time....
and dont think it gets as much out either.....some left behind in pockets.

other way is much more laid back.....

I always keep a couple of those $6 HF hand pumps around....but they rarely get used......they instantly start to degrade after each use....

And every taco owner should have a hand $18 vac pump /gauge combo.....with that there you could draw anything off into a home made bottle...

 

I hit 300k in my similarly specd 01. The 3rz is the true hidden gem.

 

Purchase fsm from bishko automotive literature. It's the keys to being able to handle what you're about to deal with.

 

Lazy and don’t want to drag out the jack and jackstands? I fold up 2 lawn and leaf bags, put them behind the front tires and back up to put the front tires on them. I can spin the steering wheel with one finger.
