Two reasons to bring hot coolant to the heater core. 1; for the heater, 2; to mix in a bit of heat to give you AC temperature control. The problem here is we are getting heat from the heater core, even though we are telling the system to not give us any! The water pump does not care where or or...
With all due respect, all the equations,and formulas, and hypothesis, mean nothing in the real world. We know the automotive AC is capable of blowing mid 30 degree temperatures, and the hack proves that our Rams are at least capable of blowing 40 degrees all day long. Its really very simple...
Thank you, and to plenty of people (not knowing their vent temperatures), that would feel just fine. Feeling cool, or cold is not only subjective, its also relative.
AC is cold, no water leaks, average 16.5 -17. mpg 50/50 city/highway. More than happy with my Ram! I've had 3 brand new trucks in 6 years, If I were not happy with this one, I would not have it.
I get where your coming from, but it's just a rubber heater hose, not an AC line or anything. Now if I were to come in with a heater core problem, (leaking or clogged or whatever) and they see a shut off valve, I would have a problem.
Cheers,
The engine fan can really get going on these Rams and It seems the more you push the AC, the faster it goes, (by design). Could you be hearing that? If not, it could be a noisy blower motor, going bad.
Yes auto on, ramps up your blower fan to a secret 8th fan speed setting, and speeds up your engine fan as well. I can get 40 degrees blowing with auto at 90+ outside, and 42-44 degrees blowing non auto, (with AC hack).
You do understand the clamp is designed as a temporary solution to stop coolant leakage when the system is being worked on? Using them long term could crush and degrade your hose. The valves are designed to be permanent. Every one makes their own risk assessment, and you are making yours...
