I have 2 hoses in question.. there both coming from the fire wall.. One isnt actualy a hose, its a metal pipe of sorts that it looks like a hose should clamp up to.. its about the middle of the car at the top of the fire wall.. and the other one is over to the drivers side a bit.. its actualy a hose that isnt blocked off its just cut... I have been looking through my haynes and i cannot find a picture that shows it so i can figure out what there for...

my car is over heating so im having a feeling its part of the heater coar that for whatever reason the guy i bought it from may have cut them trying to find the problem.

StinkyFatPig

oh i forgot to ask.. is there any good pics around that give a good shot that i could pont it out to you guys?

They'll be the cut off ends of the A/C refrigerant lines. Picture 14.10 on page 110 of the Haynes manual shows one of them.
They won't have anything to do with your cooling problems. If they were coolant hoses all the coolant would run out...

what is the diameter of the "pipe" thats about in the midde? is it a brassy color? possibe heater hose connection.

if that is infact what was cut then like NZConvertible said all the coolant would just run out, unless the previous owner ran a coolant hose to bypass the heater core. if thats the case ya might wanna check the heater core inputs and outputs at the engine just to make sure.
BTW the heater hose connection by the spark plugs has a tenency to fail as oil and stuff leaks on it deteriorating it.
does your car smoke? when you try to add coolant does it bubble out with the engine on?

good luck

the pipe coming out is about 3 inches long and is about a 1" or so.. its a brass color... I hear ya abouthte fluid running out.. but there is that other tube which i was thinking may be the return.. and if the kid just blocked off the lines coming from the motor..
I ran out of sunlight last weekend so i couldnt track down the send and return line from the block to see if that could be the cause..

Is the car running?

Sounds like the heater core is blocked off.

StinkyFatPig

yeah I was thinking the same thing.. and because of my over heating problems that might be a good place to start.. does anyone know for sure if those are the heater hoses?

Aswell.. does anyone have a good picture that i can use to point this out? I ask cause there is a few other hoses that are cut.. and I have to figure out if the guy blocked the air pump hoses...

and there is one that im worried that there is a vacum leak..

TonyTurboII

My engine bay is pretty empty, ill snap a pic of the firewall when I get home so you can point the connections out.

StinkyFatPig

that would kick ***....

the guy that had this car before just made such a mess of this motor.. did a bunch of his own wiring that is just so sloppy.. its bad.. he sheared off bolts on the air pump then didnt take it off.. I guess he lost one of the bolts for the termistat housing and just screwed it a standard size bolt cause it was close to the 12 mm...

just brutal.. like come one.. hardware stores charge like 25 cents for the bolt.. Now i have to rethread it etc..

TonyTurboII

Here ya go. If this shot isnt showing the right area, let me know I took a few others.

TonyTurboII

Oh yeah, and im going to scrub that engine bay back to its black beauty as soon as the block comes out, so no dirty engine bay cracks!

StinkyFatPig

I am assuming that is the one with the little pipe..

I am having a bit of a hard time following it.. coudl you do one that is alittle farther back so i can match up parts of the motor with where it is alittle easier.

TonyTurboII

Hows this?

BTW, the one you pointed to earlier is a heater hose, going from the heater core to the water pump area.

StinkyFatPig

ok now i know why the picture didnt look right.. you have no motor..

anyway.. I belive that was the one and it looks the the other one is the other line that is cut.. would that be the other heater line?

I think i might have to just rip the whole cooling system out and re do it completly... I noticed this Y valve in some lines and i have a feeling thats what he did with the heater line.... I still havent figured out what or why its there..

thanks alot for the help man.. Greatly appreciated

StinkyFatPig

oops forgot the pic

TonyTurboII

No Problem.

Actually, the hose leads to a metal tube, and joins up to the lower radiator hose, at the bottom of the radiator.

The coolant feed comes from below the oil filter, curving up around the back, drivers side of the engine.

This will not be the source of your cooling problems. You can completely block off the heater core system without more than a few fractions of a degree in coolant temperature change when the heater fan is not running.


I would be curious to find out how, and why they blocked it off. Probably a pinhole leak in the heater core, causing coolant to spill into the interior, and creating huge amounts of steam and fogging the windows. The part itslef is decently cheap, bu the labour to replace it is extensive, requiring removal of the dash.

scathcart

Could you do me a favour? Look for a fitting of the same size coming out of the lower radiator attachment on the passenger side bottom of the rad, and tell me if there is anything attached.

Also look below the oil filter for a similar nipple, and tell me if anything is attached.

StinkyFatPig

there is a hose coming from the bottom rad hose.. I figured that had something to do with the heater coar.. I was planning on looking into that but again just havent had the time as of yet to look at it.. I will take a look under the filter tomorrow, dark right now so i cant take a look..

As for why he blocked it off.. I figured a leak or possibly because of the other heating problem he may have thought that there was a blockage and just decided to block it off other than replace it..

I understand what you mean about how it shouldnt effect it overheating.. but I am pretty much at a loss of ideas.. rad has been changed, water pump is pumping.. thermestat works(and has been removed forthe time being.. I have run water through the system many of times and it seems to flow through fine.. so no blockages.. I just cant figure it out.

scathcart

Where in BC are you located? I could probably figure this out.

How do you know it is overheating? Are you running the stock fan? Do you have the shroud and belly pan in place? Have you checked the fan clutch?
You need a thermostat for proper cooling, BTW. You can mod the thermostat to be open all the time, but you need it in there as a restriction to flow.

StinkyFatPig

I live in nanaimo on the island.. so a bit of a trip..

well as for why its over heating.. I bought it off a guy that thought the water seal was shot.. and thats why it was over heating.. but as far as i can tell there fine cause its not burning any rad fluid..

I run the car for about 30 mins or so then i get my overflow starts to boil.. the temp gage isnt too high, it is higher than normal but not to bad.. but the water is boiling in there. I have taken the fan shroud off just to make it alittle easier to work on.. considering the size of it, I bet it would run alittle cooler with it on but i couldnt see it makeing that huge of a diffrence.. and it was still overheating when buddy had it withj the shroud on.

V8what?!

With the stock fan on there, I would recomend still having the shroud on. Try putting it back on, and try putting your thermostat back in too. Oh yeah, and buy a flashlight.
