[urq] Swapping out the heater core? Thoughts?

[Keith Lloyd]

JP
Be careful (I'm sure you will) dismantling the AC. When I bought my car in 
2001 as a pile of crap, I was told the AC didn't work and was empty and set 
about stripping out the engine bay. I started disconnecting one of the 
bigger AC hoses when it suddenly came free and nearly took my head off 
realeasing all the refrigerant in to the environment. Not one of my proudest 
moments but at least I escaped injury.
Regards
Keith
