High output heater core?
Can I use a high output heater core in a non-high output heater box? If I remember there was a metal plate that the heater core sits on so would I have to remove that plate to make it work or what else would I have to do?

before you do anything pull both lines off your heater core and take a small piece of 5/8 copper pipe about 3" long and cut a old garden hose off hose clamp all together and turn water on full and see how much flow and crap come out the other side if your truck ever had any rad sealer in a can added that were it seems like it always gets stuck my heater didn't work at all and I did this and after about 5 seconds a big wad of brown stuff shot out of it and flew all over the rad support and its worked great ever since

Cipsmithers, how much pressure can a good radiator or heater core
take before busting? :) Please ask if you don't know off hand ok? :)
The water pressure on your garden hose is prob'ly over 40psi and
maybe as high as 80psi, so try to be easy with it.
Even with the facet turned on -real- slow the pressure -can- go to
full pressure if there is enough of a blockage. Do you see it? :)
-->And don't be running no dumb ol' 160*F thermostat or even a
sorry 180*F thermostat! :/
Run a 195*F thermostat like the system was designed to run. :)
Your engine, heater, gas mileage and engine-oil will thank you. ;)

Alconk,
I did read a post where someone just opened up the heater box and modified it to fit the high output core, but it seemed like to much work to me. I just went to the local pick and pull and found a high output heater box that I cleaned up and put a new core in, even got the decal for under the heater controls, and the box only cost $10.
Some things to check first though:
Once engine heats up touch both in and out hoses to heater core --both should be extremely hot.
Check control cable setup --doesn't matter if core gets hot if heat/cold control door will not let airflow to core.
Cab and fresh air vent seals --could just be too much fresh air coming in and diluting hot air from heater.
Hope some of this helps,
Jeff
