4agze water inlet pipe.

[Quirky]

Driving on Saturday night *crack* steam and water pissing out.
Turns out the water pipe has cracked.
Ive gone through TOYODIY:

Engine is a ae92 map sensored 4agze and that inlet pipe looks different to the one I have?
Maybe I am looking at it wrong but is this the right water pipe?
Any hints on the best way to replace it?

normal 16v water pipe found on all 4ages in FWD

its strange for it to crack? didnt blow the seal against the waterpump?

oh and PS to get this off on my aw11 yesterday i had to remove the intake TB and supercharger....

good luck

4agze ones are different to 4age ones.

[sergei]

I believe I have an AE101 GZE pipe laying around. I will have to double check if it is there.

[mr30%jr]

not on AW11 EXACTLY the same part number. even on a FWD corolla?

[themaleman]

like bazda said, thers a difference, if you use a 4age 1 ull need the matching block thingy it bolts onto on the cambelt side of the engine (part 16331)

[mr30%jr]

16331 has nothing to do with that pipe... it attaches to the back of the waterpump

[Quirky]

My 4agze is turbo now with the smallport intake manifold. Can these stay as they are?

[Quirky]

ahh ok, the diagrams used on toyodiy are the same for all the 4ag. However they do list different part numbers. Thats all I needed.

[themaleman]

my bad wrong pipe

[Quirky]

Alright got the pipe out. Surprisingly easy, took about 10 mins.

There was a braket that was welded onto the pipe that broke. No screws on the original mount, weird.
Is this a 4agze water pipe? It looks different to the diagram in original post because it only has one bolt mounted to the water outlet thing.

Im not going to buy a new one, im gonna get a shop to weld over it.
Any problems with this idea?
New one is $140 from Japan...

[Quirky]

ohh woops my mistake, the pipe i highlighted in the original post is a different water pipe. its suppose to be the pipe above it....

[mr30%jr]

ahem...................................


yes. well THAT pipe is diferent thats the heater bypass hose.

[Quirky]

heater bypass aye?
Should be sweet to weld over it then?

[mr30%jr]

NO lol no its not ok to weld it up....

what that does is feeds water around the head and block bypassing the the thermostat so the car can get warm, pump water around and get the heater warm too.

without that water would sit stationary in the head and block, boiling and rooting things , the thermostat would never open.

wats with the brack thats been welded ot it....

the hoes just hasnt cracked someones made it weak by welding to it then its ripped a chunk out.

[Quirky]

Apparently the original bolt screws to the supercharger? But because of the supercharger removed it doesn't bolt to anything...I think thats how the workshop explained it to me.

[themaleman]

ahahahah so i was right! you can see the difference i was talking about in your pic, your 1 has the bolt bolting the pipe to the casting on the left side, where the pipe in the diagram has it on the right.

[Quirky]

Yea my mistake.
The workshop who built my car offered to fix it at no charge, so i dont have to worry about it.

[sark.inc]

looks like a fair bit of corrosion on that pipe, you are running coolant right, not just plain water?

[Crucible]

NO lol no its not ok to weld it up.

why not?, its only mild steel tube. Ive brazed a few coolant pipes in the past.

as long as its not corroded too badly, welding is definately an option.
