ok so i started the 7 today and all my coolant leaked out just as fast as i poured it in... the car has been sitting for about 6 months and before it sat it ran good ive never had a coolant problem. has this happened to anyone, or can someone post me up a pic of all the coolant lines for i can check them and if maybe a line got undone or something? ohh and it a vert 90

thanks april

 

where is it leaking out at?that will help alot........

 

coulda been a rodent or something chewing?

and knowing where leak is comming from is a good idea.

 

Not a very helpful post Where is it pouring out from? If it's going out that fast, it has to be leaving a mark/spray somwhere. What I'd look for: Any sign of smoke, cause tha'ts coolant hitting something.

specific areas:
-The coolant line that runs from the engine block to the firewall, underneath the throttlebody, behind the oil fill neck.
- The other side of this is the line that runs over on the passanger side frame rail, from the firewall to the lower radiator hose
-The two big radiator hoses, of course!
-Inside the car! You may have a broken heater hose on the inside, but you'd notice/smell/feel that much coolant in there.
-check your radiator for leaks, you'll see it spring out
-around the waterpump (second tot he top pulley, right underneath the alternator).
-Thermostat/Coolant Add area.
-Exhaust! If you're losing that much coolant through your engine, you have some big problems... This much would be a thick white smoke out the exhuast.

Good luck

 

from what i could see it looks like its comeing from somewhere in the back of the block, leaking all the way down.

 

-The coolant line that runs from the engine block to the firewall, underneath the throttlebody, behind the oil fill neck.... this sounds the closest.. to where it might be leaking because its leaking like a waterful around that area

 

Yeah, that one broke on me, too.. It looked like my tranny was leaking coolant Right at the end of the block..

 

exectly! is that pretty hard to change?

 

no

its one of the easiest...

 

so its coming from the actual block itself??? the only hoses i can think of that are near the block are the heater hoses, then ther are those going to the BAC but it doesn't sound like that to me. Perhaps its the hose coming from under the TB?

 

my guess is for the BAC hose.. The other one is kinda obvious


Edit: in my description above, I mixed up part of the BAC hose, and part of the heater hose! DOH! I meant hte BAC hose, going from the middle of the engine block up to the back of the throttle body, for those playing along at home!

 

shouldn't take more than 5 minutes to change...

here is visual aid

I would say for tools

a good set of channel locks (this is to remove the hose incase it sticks), but I would recommend using hand power to remove it.

and a 10mm wrench or a socket wrench and 10mm socket with a 6-10 inch extension.

 

all the red arros in picture point to possible leaks... Right... someone correct me if I am wrong

otherwise check all these spots.

 

ok this is where i think its coming from then.... because this is where im seeing all the coolant....

 

wow.... why is it always the super hard one?

That one is a pain... only because it is buried a little under the upper and lower intake...

you will need to be able to see back there and have a pair of L bend needle nose pliers (to remove and install the hose clamp)... something with a grip medium size... and maybe the channel locks to remove the old hose and also put on the new one.

 

nice informative thread.
that sucks. it looks hard, but do what u gotta do.

 

yeah im going to do it tomorrow, and im hoping thats what it is.. i'll let ya'll know how it goes... thanks for all the awsome info and pics they are all VERY VERY helpful.!

 

with some patience, you can get to that coolant hose on the rear iron without pulling the manifolds provided that you have a screw clamp on that hose.

can i also get a pic with the tb mod and the rats nest removel?

 

On my writeup? I don't have access to a stock NA right now. The hoses are the same regardless unless the cold start was removed from the throttle body. In general when people do something dumb like that they also pull the BAC valve (also dumb) and either loop the coolant hose from the rear iron to the water pump or just plug both nipples.

 

heres a pic of where its coming from... the passager side. btw i know that im pointing at that fuel line, its leaking under that line down there.





bad thing is that when im feeling down there i cant feel any lines!...also, i know that its bad to start the car without coolant running to the block, is that the only way that i can possibly find that leak is by starting it, and letting the coolant basically run out of the car, or is there a different way? to where i dont have to start the engine?

You can pressurize the cooling system which should force the coolant out at the leaking point. Check with an auto parts store for the tool to do that.

 

I don't know if this will help but it gives you a better idea of what is in the area your pointing to.

 

The leftmost red arrow is the heater hose. Common leak point.

The rightmost arrow is the coolant feed for the throttle body/BAC. Since you don't have those hoses, your BAC/TB nipple is capped. Very common for a leak to develop due to improper capping.
