I have no idea why or how but i THINK i have coolent coming into my cabin from the foot vent in the car and its all over the carpet and it only comes out when i corner?????

My car did over heat a lil the other day but now its all back 2 normal but i just wanna know why this shit is leaking into my car?!?!?!?!?

Plz help!

Umm MadGT4. of course its coolant, how do you think your cabin heater works, engine coolant is pumped through the firewall and into a metal heater core. It corrodes like any other part of the coolant system.

Id seriously stop driving the car whilst its leaking, loss of coolant will cause your car to overheat and if you think running an engine without oil is catastrophic, wait till you run it without water! Best way to bin a motor.

Id doubt its just a hose leak, or else it would be leaking more constantly.

Heater cores are not easy to replace, they involve removing alot of the dashboard. If i were you id get the screwdrivers out and remove the core yourself then take it to a radiator shop for repair. Or else you'll be paying a mechanic at 50-80 dollars an hour to do a job that could take a whole day to do.

Bugger!

Thanx for the tip looks like i might be doing that then

And its not inconsistant its like consistantly leaking so yeah and mainly on the passanger side for some unknow reason, theres only a very small amount coming into the drivers foot well...

Um now does anyone know how easy/hard it is to remove basically all the dash like Red17 said?

Although the liquid is probably coolant, it could be the aircon's refridgerant. When I had a leak on my AC system, I took it to my nissan dealer who regassed it and added some kind of green dye - the idea being it would be easier to detemine where the leak was coming from. The dye looked exactly like engine coolent...

if the leak only occurs sometimes, check to see if it only happens during/after using the AC...

i had this, started off small, the one nice winter morning the thing sh!t itself and i had steam billowing out the windows! bypassed the core and had to buy a new core for almost $400! just need to put it in now!

guys if ur heater is the problem u can still drive it as long as u turn the heater off . if u have climate control put the temp on the lowest seting 18 deg .

one way to check if its the heater when the car is at normal temp and when the ambient temp is say bellow 24 c put the heater on at the highest seting thats when the coolant should come in the cabin .

I guess its more pronounced, when the climate control is using a bit of heating to get a nice temp. Set at about 24c (18c gets too cold, even on 35deg days!) i guess that is when its been happening and it would be swapping between aircon/heating to maintain that.

Today - after removing my floormat, and seeing how much has been coming out - the loss from the radiator *does* match the leak, and its bigger than I inititally thought. Even just idling at standstill was enough to take a noticeable amount from the radiator.

Anyhow, i'm on the case... i can't drive around much with this happening for too long, as there is the risk of cooking the engine if it isn't topped up enough. Anybody who is having this problem *always* check the water level in the radiator and top up as necesary. For those that aren't aware: NEVER do this when the engine is already hot, as cold water into warm engine = cracked head

ok, well this arvo i've been pulling it all apart. Took some photos too..

First photo is the coolant that you can see on the carpet.. 2nd is the actual water as it drips down. While it looks like one exact spot, water is actually leaking from a number of places to under the carpet.

Further to wrxhoon, its not actually *that* hard to get to I didn't think once you have worked it out.. You can remove the whole glovebox assembly, letting you get easy access to behind where all the heater stuff is. No need to remove the whole dash.

Getting too hot so i've had to take a bit of a break, will keep updated on future progress.

ok, here is the glovebox after i'd taken it out..

To remove it, there are about 6x screws (circled red in the attachment). 2x of these are actually the catch to the glovebox, but you'll have to remove these also. Trickiest one is the one bottom right, which you'll have to do with the glovebox open, and using a long philips head to get in there.

After that you'll have to kind of pop the clips out (circled green) which attach to the upper part of the dashboard. I snapped one because its hard to do it without doing that :D but superglue will fix it.

Once you've done all that, you should be able to lift it all out as one piece, allowing you to get to all the heater stuff...

This should be what you can get to after you've got all the glovebox out. I assume this is the "heater core", although i'm still not quite sure what that means, i guess its like an element.

I guess i'll find out once i get it apart and/or out. Looks like you can take the bottom part out. Thats my next attempt :D

Yeah that looks like the airconditioning unit,,in behind that is the heater core,, it looks like a minature radiator with plastic surround with 2 plastic hose connections coming from it,,,,, i called Natrad in melborne and they got me one supplied for $250 brand new shipped down from canberra.

    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
    • When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
    • So I found this: https://www.efihardware.com/temperature-sensor-voltage-calculator I didn't know what the pullup resistor is. So I thought if I used my table of known values I could estimate it by putting a value into the pullup resistor, and this should line up with the voltages I had measured. Eventually I got this table out of it by using 210ohms as the pullup resistor. 180C 0.232V - Predicted 175C 0.254V - Predicted 170C 0.278V - Predicted 165C 0.305V - Predicted 160C 0.336V - Predicted 155C 0.369V - Predicted 150C 0.407V - Predicted 145C 0.448V - Predicted 140C 0.494V - Predicted 135C 0.545V - Predicted 130C 0.603V - Predicted 125C 0.668V - Predicted 120C 0.740V - Predicted 115C 0.817V - Predicted 110C 0.914V - Predicted 105C 1.023V - Predicted 100C 1.15V 90C 1.42V - Predicted 85C 1.59V 80C 1.74V 75C 1.94V 70C 2.10V 65C 2.33V 60C 2.56V 58C 2.68V 57C 2.70V 56C 2.74V 55C 2.78V 54C 2.80V 50C 2.98V 49C 3.06V 47C 3.18V 45C 3.23V 43C 3.36V 40C 3.51V 37C 3.67V 35C 3.75V 30C 4.00V As before, the formula in HPTuners is here: https://www.hptuners.com/documentation/files/VCM-Scanner/Content/vcm_scanner/defining_a_transform.htm?Highlight=defining a transform Specifically: In my case I used 50C and 150C, given the sensor is supposedly for that. Input 1 = 2.98V Output 1 = 50C Input 2 = 0.407V Output 2 = 150C (0.407-2.98) / (150-50) -2.573/100 = -0.02573 2.98/-0.02573 + 47.045 = 50 So the corresponding formula should be: (Input / -0.02573) + 47.045 = Output.   If someone can confirm my math it'd be great. Supposedly you can pick any two pairs of the data to make this formula.
