You'll probably have to remove the old leaking heater core from under the dash.A chiltons or haynes shop manual would be very helpful in telling you the actual step by step proceedure for removing the old core and installing the new one.I've replaced several heater "cores' and it involves a good bit of body contortion to get you head under the dash to see what your dealing with,but I,m confident that you can get the job done.Don't skip any steps here cause that way leads to frustration.Be sure to have a small bucket or tuperware container handy to catch any excess antifreeze before it soaks you carpet.

try bleeding the heater matrix out to remove the air,with the heater switched to hot,disconnect the out flow pipe from the engine end with the motor just warm, (so you dont scold yourself), till water flows well then reconnect pipe and top up system, if theres no flow then you need to flush the matrix out by disconnecting both water pipes and connecting a hose to the in flow of the matrix and flushing out till water runs out the out flow end,then reconnect hoses and bleed out, top up rad or heder tank and check anti-freeze.
1) Drain engine coolant. 2) Remove all cowling under the centre of the dash for access to the matrix.3) Remove two water pipes from matrix.4) Disconnect heater matrix valve cable.5) Remove matrix being careful not to spill water over the ECU. Reverse instructions for refit. 6) With heater turned to maximum heat, top up cooling system with 50/50 anti freeze/water ratio. Run vehicle and check that the radiator is free of all air and that the radiator fan cuts in when hot. Run the car and recheck coolant level over the next few days of running in case of leaks. Check under dash in case of leaks.
either the heater matrix has gone and your gettin fluid from that or its comming in from a hole in the bulk head with the age of the car i dont think its a rusty hole see if the top of the foot well carpet is wet around where the clutch pedal is or you foot goes if its wet that far up it the matrix
You need to check your heater core, these commonly leak which will let anti-freeze into the cabin and can cause you engine to overheat and cause damage to the motor. Check the carpet in the footwells for moisture.
hi this is your heater matrix inside the car has blown or the hoses have split, unfortunately there is no quick fix for this as it is under the dash and takes allot of time to take it out and replace...hope this helps
Does it have to do with the AC. I had a similar problem with my vitara and they said a washer was prob loose in the ac system which would cause the water to leak to the footwell. Mine was only the passenger side.
you will need to take part of the bottom of the dash away but you wont have to take it out completely.
not done this for a while but as I recall you can slide it out the side near the passenger footwell.
like I say it was a while ago when I done it so not fresh in my head.
look where the fan is see what access you have around it.
