Heater core

[terifi]

yep just as the title says...i got a problem with the heater core...it leaks ...and im in need of replacement...bad ...i already know that by itself a new core shouldnt be too expensive...but the labor will kill me, which is why im gonna have to do it myself....

what i need is good advice...and i kno alot of u out there have it.

first off what size fitting do i need so that i can pull out the two hoses from the heater core and put them together...to avoid the engine overheating

and second....im sure its gonna be difficult to do...but anyone kno where the heater core is...behind the dash...and whats the easiest way to get to it and swap it

thanks!

ahhh, ok, thanks, now for a few questions,

i havent actually looked behind the dash yet, but do i truely need to remove the ducts...or am i just detaching them from the heater unit..

and how much easier will the job be if i take the front seats out...or will that just make it more difficult?

i knew somebody had an answer

You'll most likely need to remove the ducts. When you remove the center duct off the top of the heater core, then you will have nowhere to move it if the side ducts are still connected. It will need to be out of the way so you will have room to wiggle out the heater core. I'd take the front seats out. It's not hard and won't take long and it will give you way more working room.
