Heater core is leaking now and i just dont have the time to replace it as im meant to be going away. Can i just use a bit of hose on the heater tap to bypass it?
Cheers
sure
but with taps being $30 or so...
so it wont cause any damage by doing so?
No damage just bypass it.
You can check my thread about this. If your core has been leaking and you want a bypass hose that cancels out the heater tap and the heater core, make sure you bleed the system as there's bound to be airpockets from all the leaky coolant. I havent came around to deleting the heater core from the car, as I have seen its takes a whole day to remove it with the proper tools (and experience)
