Yeah, take out the whole box and do it on your bench. While your at it changing the core, buy a new gasket kit and change out all that old decayed foam.BB1966 said:You could change it in the dash but its not that hard to get the whole box out. The four nuts in the engine bay around the blower motor and some cables and the water hoses and its out. Much better on the bench than on your side in the floor of the car!
thehueypilot said:Maybe it is just the heater hoses that are leaking because they are old and dry rotted?
krash kendall said:Unfortunately, you have to pull the whole box out anyway if that is the case. For the cost of a new heater core, you might as well change it regardless. And just a heads up: The leak you have is the current weak spot in your pressurized system and once repaired will expose the next weakest. So, be prepared for a potential rad leak if your rad is questionable.
My dad used to work at a Nissan dealership and they absolutely refused to change the heater cores in the Nissan ZX's. The car was built around the heater core. It only paid 3 hours, but it took about 3 days to do. Dad talked with a guy who had done several of them and eventually got it down to 12 hours.Don't feel bad. I had to do the rad and and heater core in my truck two weeks ago. Would have cost close to two grand at the dealer. If you haven't seen the pics, here they are:
Steering column and dash had to come out
