A/C not cooling fast enough
A/C not cooling fast enough
my a/c will eventually get cool but not really until I hit the highway. The increase-speed fix may be a coincidence but I swear the a/c doesn't get cool until i get on the road over 60mph.
I've also noticed (for some time now) that there is a knocking that sounds like a...bear with me... a jack hammer off in the distance.:o
Any suggestions on what to look at as I'm not to familar with the HVAC system.
p.s - I did replace the heater core 6 months ago and hated it. I also get a gurgle sound on hard acceleration in the HC.

For the A/C, my first suggestion would be to put high and low side gauges on to see where things currently stand. Might be something as simple as the system overcharged, or as bad as a compressor failing.
If you don't know what you're doing with the A/C - let someone else work on it. There are high pressures and temperature extremes involved where a wrong move could result in further equipment damage, or worse yet - personal injury, both of which offset the savings of doing-it-yourself.
As to the heater core gurgling, is the coolant level right and all air out of the system?

As far as the HC goes, I have the proper coolant level but assumed it had air in the system. How do I purge it out?
The air should eventually bleed itself out through the overflow/reservoir system on typical systems.
I know that some vehicles have a separate purge port if the radiator is not the highest point in the system. On an old Honda I had, this port was on the engine's upper radiator hose outlet. Not sure if Ford is needing to do this on its newer trucks???
Another thought with the gurgling - are there any flow restrictions, such as a kinked hose or the like? Anything goofy going on, like the outlet heater hose is larger than the inlet?
