your heater core has sprung a leak.

Either the hoses leading to or from this heater core, or the core itself has sprung a leak. It needs to be investigated.

‘the replacement heater coil is bigger than the original. You will have to trim the flow pipes & remove the transmission tunnel cover to fit it in place,
