Why does my compressor line get hot when the temperature is outside?
There are three sources of heat that affect that tube… (four if you use the compressor when the temperature outside is really, really hot!). The process of compressing air in the head generates heat in the compressed air itself.
What to do if your heater is blowing cold air?
Coolant level: If your coolant level is low, your heater core may not be getting enough warmed coolant through it to produce adequate heat. Solution: Top up the coolant and see if it helps. If the level is low due to a leak, track down the source and get it repaired.
Why is my hot water heater blowing cold air?
Heater core exterior: The heat-radiating fins on the outside of your heater core could also be clogged with debris that makes its way in from the outside air intake at the base of the windshield. This can affect the heater’s output.
What should the pressure be on an air conditioner?
At 85 degress f and engine rpm at 1500 high side should be 200-250ish low side 20-30 ish. at these pressures the low side line at the evaporator should be cold and sweating. If the refrigerant charge can be adjusted to achieve this (venting is illegal) and still no cold air, the heater/blend door could be stuck or leaking.
What happens if one heater hose is hot and the other is cold?
I read that if one hose is hot and the other is cold, then the heater core can be clogged. What could be the issue if both hoses are cold? The three possibilities are stuck open thermostat, stuck closed heater hose valve (if there is one) or plugged core. heater hoses stone cold….radiator hoses HOT….
What causes a heater to blow cold air?
The following are some issues that may be causing the heater to blow cold air: Low coolant levels. A plugged/clogged heater core. A faulty thermostat (thermostat that is stuck) Broken blower and/or blower motor. Heater core bypass hoses that have leaks.
How are the hoses to the water heater connected?
It does appear that both heater hoses are connected to the thermostat housing. However one hose has to connect to the suction side of the water pump and the other side to the pressure side of the water pump. Otherwise no flow. This is a curious and unusual design.
What to do if your heater core is cold?
With the engine cold and you’ve got reasonable access to safely disconnect your heater core hoses one at a time, disconnect one or the other and have a friend start the engine. I’d personally try to find the heater core return hose and disconnect it at the engine.
