Steam Coming From Window Demister/very Funny Smell

[SKYL1N]

recently i have noticed that the front windscreen has been fogging up at the bottom in the center, even in the middle of the day, but its almost a steam like fog that moves around, gets bigger n smaller n moves around a little bit but generally in the centre of the windscreen.

this also started with almost a burning smell everytime i turn on the air conditioner/heater

now today the temperature gauge was reading high and i found out there was no coolent in the radiator so i filled that up and it doesnt appear to be leaking.

the steam is still evident and the smell is still evident

it almost smells like a burning oil smell.

anyone know what could be happening or have had this problem before, im really hoping someone can guide me in the right direction here.

p.s did a search found nothing

i got a bad feeling your heater radiator has a leak in it...

maybe just a small leak to cause steam but no drips..

only thing i can think to test this is drive around for a little while with the radiator cap loose so the system doesnt build up pressure and see if it still does it. dont drive like this for 2 long and you will probably need to bleed the cooling system again after.

dont know if this helps but give it a shot.

yeah sounds like you have a leak somwhere in the heater box and that is causing the smell, the fog and the overheating and loss of coolant.

first thing i would be doing is disconnecting the hoses that go into the cabin from the engine bay so that you don't loose any more water and damage the engine. then find the tutorial on how to remove the heater box and have a look for signs of a leak

If i do keep losing water and just keep topping it up before it gets low i should be able to drive for a week or so yea?

i wouldnt baby it, as babying doesnt really change too much

i had a small leak in mine years ago, couple days later sitiing in peak hour morning traffic it burst and filled the cabin with steam lol was probably pretty funny to watch, but not cool for holding coolant.

really need to look at bypassing it quickly

[SKYL1N]

hmm got quoted rougly 700 to replace it, so looks like ill be bypassing it. is this hard to do?

quite easy to do, grab a set of pliers, and some steel pipe or the likes.

Disconnect the 2 pipes going into the passenger side of the firewall and then push the steel pipe into one of them and use the hose clamps that were originally used to clamp it, then connect the other pipe to the other end effectively bypassing the heater core,

I had this problem a little while ago, unfortunatly i was left with a nice wet patch in the passenger footwell!

Since bypassing the core i have no problems, and ill eventually get around to replacing it at some point, but i dont think i need the heater for the summer

[SKYL1N]

ok so found this

excellent tut on how to replace the core yourself

so i shall bypass is asap and then once ive got a free day will DIY it

heres the link for anyone who wants it, a very good read

Same thing with my r33. Any long term problems leaving it permanently bypassed? I live in Cairns and it never gets cold!
