On my 4.6 liter Ford engine the heater core inlet hose looks like it's connected to a pipe on the rear of the intake manifold. There is no possibility of cutting that host the way it's tightly looped near the fire wall. So I'm thinking maybe I will find out what the inside diameter is then go to the auto parts store and get buy several feet of hose, cut in two, install the "T" fitting, then loop it around and connect one end to the H/C hose, the other end to the connection on intake manifold.

I have a 1999 Concord LXI just bought it.. It is overheating. I replaced the thermostat and replaced a blown fan fuse. it ran fine for 1 day and then started to overheat again, the fuse was blown AGAIN.. I am flushing the system Saturday, thinking it may be clogged with lots of crap. Would a clogged radiator blow a fuse? any ideas? anyone?

This is not an issue. I've seen technician flushed the heater core back and for, meaning disconnect both hoses and flushed the core from both directions. Anyway, to prevent blockage anywhere it was customary to 'reverse flush' the whole cooling system in every 4-5 years in order to take care the radiator, the engine block and the heater core in one relatively easy step

The bigger problem is the blocking up of the heater core.

My sable wagon has had issues with no defrost for years.

when you try to force water through it , it is plugged.I found that you have to flush

both directions both in a pressure and a vacuum mode. It is the only way to get

the crap out of the core. If it's plugged all the pressure in the world will not unplug it.

In the UK if you have been certified, it means you are insane. I think what he meant to say was, if you are not sure ask a qualified mechanic.
