I need to replace the hearter core in my 97 F150. I was hoping that someone
could tell me the easiest way of getting to it. I have no heat and the
fluid is brown. I flushed it out,ran clear after about 20 mins.Now it is a
little brown and no heat.

There is no easy way, you have to remove the whole dash/facia and then
remove the whole HVac Unit (aircon/heater thingy) and then pull out
the damaged bit and replace it.

No difficult, but a time consuming job with a high probablility of
breaking plastic bits during removal and replacement. I would not
attempt it without a WS manual.

Once you have replaced it, Just fill the cooling system from the
hightest point (on my landy, that is the thermostat housing) and keep
topping it up every half hour or so. Also works better if you can park
it facing uphill as this helps bleed the system.

Eventually when you think it is pretty full, leave the top up point
open and fire her up, run the heater on full as this helps to bleed
the system, then just squash the cooling pipes to try and dislodge any
airlocks and top up if neccessary.

Then replace plugs and go for a short drive and when the system has
cooled sufficiently, check the expansion tank and top up if required.
Check it every morning for the next week, and by then you should have
no air in the system.

PS it goes without saying that you use antifreeze so as to prevent a
recurrence of the same problem.

I'll reiterate, no easy way to get to it.. BUT -- there is a flow
restricter you should make sure you install. It may prevent you from
having to do it again.

set to full hot, otherwise you can get a nasty inclusion of air in the
cooling system, and it can do some real damage.
