heater core bypassing or replacement

[351inside]

how do you go about bypassing im really not looking to take out the whole dash, im getting small leak inside the car and i believe its the heater core, the drops are in the driver side though... anybody can help with this thanks

Or should i just replace it?

well bypassing it sure is alot easier!! summer's coming up so at least you wont need it as much

all you would need is a 5/8" to 3/4" adapter

what do you mean by that? im sorry i have never done this and i would preferrably just like to bypass it... Thanks

Of course replace it.

Another winter will be here at the blink of an eye.

i just meant that if given the choice between replacing a heater core or bypassing it - that it is a much easier job to bypass it. but then the problem is that you then would not have heat in the driver's cabin.

All you need to do is get a plastic coupler that is 5/8" to 3/4". You can find them any local parts store.

I did it on my old cobra when I took out the heater box to drop weight

Guys if I remember right I just used the tube going into the heater core..I thought I rotated the hose and just ran it to the pass side of the motor.

Not even a real question...fix it!! Bypass should only be in long enough to get it home and make time to fix it right.

Ughh, this is one problem i hope i NEVER have. Sounds like such a massive PITA to fix.

Since you asked how to bypass it...

There are two hoses on the firewall above the passenger side cylinder head. The one on the left (if looking at it from the front of the car) leads to a fitting that is on a coolant passage on the passenger side cylinder head, the other leads to the water pump.


You need to unhook those two hoses from the firewall and just connect them together.

Ironically.... my car just started spitting coolant all over my windshield and the blower smells like coolant.... FML

I would try to find a metal adapter. Plastic only if its very temporary.

adapter for what?
