Hi All
Been a while ive had my FD for a long time now just changed the clutch master cylinder was going to give her a plip up the road topping up the coolent it would not fill so topped it up with water to see what was going on. No water under car started it up no issues checked temp on FC commander all good.

The main point is low coolant alarm came on topped up some more looked in the passenger foot well and saw it was full and jetting warm water onto floor any ideas ?
Seat is removed now and floor dried and cleaned
before I stock a tear down want to see if any one had the same issue and has some advise

Thanks
Mike

 

Heater matrix core leaking

 

Check if the coolant hoses are connected securely. The pipes that poke through the firewall may also be damaged. To replace the heater core you have to remove the dash. Good luck with that! New heater cores are about Y20,000 on Yahoo Japan (acess through Buyee).

In the meantime you can block of the heater pipes in the engine bay.
