ok basically i went for a ride last night, proper hammered my car(was doing about 160 mph) got back home left my car,m went upstairs and i heard like something snapped, looked out the window and i could see steam coming from under the bonet. couldn't see nothing so i have checked it today, basically two hoses got ripped open, they in 1000 pieces somewhere on the driveway. i have taken pics and i can only assume that the bottom one was for overflow tank, but what about this one:

IS IT FOR OVERFLOW TANK?


AND WHAT ABOUT THAT ONE?
I KNOW THE OTHER END GOES TO OVERFLOW BOTTLE BUT WHAT ABOUOT THIS END? WHERE HAS IT BEEN?


and just in case i found this but have no idea what it is:


now, i have replaced pulleys,belt, and the radiator but my new rad hasn't got a hole to put a hbose for overflow tank. why is that? can i connect this little hose just next to the radiator cap straight to my overflow tank instead?

i got this radiator:



please help, i'd like to finish it tommorow but just don't want to do nothing wrong

those tubes in the first 2 pics go to the AST and the 3rd picture are the lines that go to the A/C dryer.

That hose should go to your AST unless it has been removed.

I believe that end also should go into the AST.

The other picture is of AC lines I believe. Unless you removed your AST, those 1000s of pieces could have been your AST failing in a dramatic way. If so, you are fortunate it did it in your driveway with the engine off.


Let me remind you of what you wrote at the beginning of your post....

Unless that is a typo and you meant 160 kph, then the first thing you did wrong was to drive your car like that on public roads. It doesn't do you, your community, or your car any good if you are a menace on the roads.

Sounds like you were possibly still running a plastic ast that burst into pieces?? Those lines do go to your AST like the previous gentlemen said. Upgrade to a metal AST.

sickboy2345

thank you for all the replies

the milion pieces weren't my AST, it's all in 1 piece, it was some plastic bits(like a spiral around those two rubber hoses)- sorry i should have explained.

but please tell me what should i do now? if the hose from the filler neck goes to my ast- the body of it right? so what about the other one? it runs from the ast as well and ends where? where should i put it in to? i havent got nothing on the radiator...

btw: where do i get this rubber hoses from?(or a metel ast ?)

p.s
dhays
it was 160mph but there is only one place where i drive like that, it's a public road, straight like an arrow and there is noone there - its in the middle of nowhere...u can't go wrong there, well maybe if you car can't take it...

You can get an AST at virtually any of the RX7club.com vendor's websites (rx7store.et, gothamracing.com, etc) and you can re-use the hoses that are currently there... If you removed your AST why are you asking about those hoses? Just place them back where they were taken from... So on the ground are pieces of a wire loom? That's nothing to freak out about...

The hose on the driver side of the AST runs along the subframe over to the overflow tank.

sickboy2345

i haven't taken them hoses out, they just snapper, popped, i got only pieces of them(on picture, thats what left)

which one is the AST? i thought you are talking about overflow bottle, where is the AST? i need to get new hoses as well but i can't find them anywhere i got only little bitsfromm whats left..

The AST should be in between those two hoses you are trying to figure out where they go. The AST is another component of the coolant system that is obviously not installed in your car right now.

You should be able to pick up the new line at any autoparts store and get whatever length you need. Or u can search for steelbraided lines at any place that sells air and fluid fittings in your area. Let me see if I have a picture of my AST installed. You can see the AST canister between the intercooler pipes. Mine is not stock.

+1 One thing about getting older, is you start to realize that Murphy almost always wins in the end.

Here are some pics that might help you out.


This is taken from behind and to the left of the AST. The AST is the black plastic vessel to the left of the blue IC hose and has the pressure cap on it. It is attached to the IC with the bracket and (rusty) bolt. The hose that you asked about first, the one that comes from the top of the water pump, is the hose that you can see running under the IC hose and attached on the right side of the AST.

The second hose you asked about, I believe is the one you see on the top left of the AST. It runs down the left side of the AST (as seen from this angle) and then runs accross the bottom of the radiator to the overflow tank which is below the right hand headlight assembly. BTW, the flat black thing on the left in this picture is my battery cover.

Next photo

.
This is the back side of the AST take from below and to the right. you can see the back of the IC on the right. The hose along the top is the first hose you asked about and this shows where it is attached to the AST. Going down the left side is the ribbed plastic cover of the second hose that you asked about. It is probably that ribbed cover that that shattered all over. That again is the same hose that you can see attached to the top of the AST just below the cap in my first picture.

At the bottom left, you can see the third hose attached to the AST. I believe it runs down and is connected to the radiator near the bottom but I don't know since I've never pulled the radiator.

Hope this helps. Never thought I'd take a picture of the back of an AST.

thank you for all the picsw, i'll have a closer look tommorow..one thing that concerns me is that i have never seen anythig yoiu describing as ast i 5thought the both hoser were going to overflow bottle..now im so confused.. it might become brighter tommorow - im brain dead now...

if you have any more info about them please post it(it's 00:30 now and i im goin to bed but ill go through them tommorow)

cheers

Okay, enough of the bullshit posts reaming the guy for driving fast. Judas Priest people....if you aren't going to drive these things fast, get a ******' Prius or used Yugo and be content with YOUR choices, and don't condemn others.

Thanks Dave for providing him with some factory AST photos. I don't have any of those.

Doesn't sound like he had the stock AST though. If I was a competent mechanic, I wouldn't have a stock AST either. Instead, I've got a very nice AST made by kinetek sitting in my garage awaiting the next coolant flush.

To the OP, there are a number of threads and how-to's on eliminating the AST. You can search for "AST elimination" and find some I'm sure. Those may tell you how it is plumbed when there isn't an AST present in the system.

It almost appeared to me there is a bracket directly below the hose coming off the filler neck, but it may be for the stock intake airbox and not an AST... However, the bracket looks similar in shape to that of the one used for my metal AST

sickboy2345

ok i didn't have ast, just connected this two hoses together so i got one coming out the filler neck and going straight to the overflow tank,

just filled it with water for now to check if everything is ok and it looks like it is

just one thing, i left the engine running for a while and was hoping that these fans on a radiator will go off......

they didnt..

so how long do i need to wait for them to start? or how do i check if they work?

dhays

Are you saying the fans didn't run at all? If I remember correctly, the thermostat should start to open at around 180 F (~82C) and be fully open at around 200F (~95C). At that point you have minimal coolant bypass.

The fans should start to run when the ECU senses coolant temps of about 220F (~105C). At point they should be running at the low speed unless you have the AC or parking lights one, then they should run at medium speed.

The thermoswitch should close at around 225F (108C) and this should make the fans run at medium speed, or high speed if you have the AC or parking lights on.

I could be wrong so you may want to do some searching to confirm, but I think those numbers are close. You really need a temperature gauge to know what your system is doing. Sitting at idle, the fans should eventually come on as the temperatures rise. It can take a while however depending on outside temperatures.

I think you are referring to the bracket at the bottom of the photo of his first pic? It is a bracket for the stock airbox. I only know because I happened to remove it a few weeks ago. The PO of my car had left it there since it has an attached wire bar that supported the radiator hose. I removed the bracket and just used some tie wraps to support the radiator hose. I'm not sure the hose actually needs any support, but I figured it couldn't hurt.

I've got tie-wraps holding way too many parts together on my car.
