Heating AC and Engine Cooling
Heating, air conditioning (AC) and engine cooling require a radiator to transfer heat. Heating a cabin requires heat to be transferred from an engine block. Engine cooling blows the heat out of the engine. AC uses refrigerants to cool air.

How do you replace a expansion tank on a boiler system?
Turn off the makeup water and electrical service to the boiler. Isolate any and all valves in the system. Thread the old tank off, thread tape and/ or thread sealant on male ends of new tank and thread it in. Bleed air from system as needed using makeup water. Dependent on the piping arangement, if the tank screws in the bottom of an air scoop, an air eliminator atop the scoop may be removed and then replaced after all air is purged. Note: in using makeup water valve/ bypass, do not go over 30# of pressure. Most residential boilers will have a safety relief valve that is set at 30# that will blow off at this pressure and make a mess. The makeup water pressure reducing valves are generaly set to maintain 12# of pressure. Most pressure tanks are precharged at the same 12# of pressure on the air side. Verify these pressures and that all air has been purged from the boiler and pumps, before refiring the boiler. lc
Where does cool water go after it leaves a radiator?
The coolant leaves the radiator by way of the lower radiator hose then enters the water pump in most automotive engines.
Where is the coolant fan relay at on 2006 VW beetle?
On a 2006 VW Beetle, the coolant fan relay is typically located in the fuse box, which is found under the dashboard on the driver's side. You may need to remove the cover to access the relays. The specific position of the coolant fan relay can vary, so it's advisable to refer to the vehicle's manual for the exact location and layout of the fuses and relays.
Are both fans on infiniti i30 supposed to turn?
Yes, both fans on an Infiniti I30 are designed to operate as part of the vehicle's cooling system. Typically, one fan is for the engine cooling while the other may be for the air conditioning system. Both fans should turn on when needed to maintain optimal engine temperature and ensure efficient operation of the air conditioning. If one or both fans are not functioning, it could lead to overheating or reduced A/C performance.
Where is the cooling fan relay control circuit on 96 Chevy caprice?
In a 1996 Chevy Caprice, the cooling fan relay control circuit is typically located in the engine compartment fuse box. The relay itself is often marked and can be found by referring to the diagram on the fuse box cover. Additionally, the cooling fan relay circuit connects to the engine control module (ECM), which regulates the operation of the cooling fan based on engine temperature. For precise troubleshooting, consulting the vehicle’s service manual is recommended.
What causes engine oil and engine coolant to run over 200 degrees?
Could be,
Restricted air flow through outside of radiator,
Restricted coolant flow through inside of radiator,
Faulty fan clutch,
Missing or broken radiator fan shroud,
Faulty thermostat,
Low on coolant,
Where in a e90 330i cooling fan relay?
In a BMW E90 330i, the cooling fan relay is located in the engine compartment fuse box, which is situated on the driver's side near the front of the vehicle. To access it, you may need to remove the cover of the fuse box, where you'll find the relay labeled appropriately. Ensure the vehicle is off and take necessary precautions before handling any electrical components.
How close should the cooling fans be to the radiator for effectiveness?
If it has a properly fitted fan shroud, it doesn't matter how close the fan blades are to the radiator. If there is no fan shroud the fan blades will have to be within a couple of inches of the radiator.
What is cool about zonkeys is the fact that they can be found in close proximity with human settlements.
How do you know if your radiator is filled to capacity?
Most modern vehicles have a reservoir from which extra coolant can flow to the radiator and vice versa. Coolant in this reservoir usually indicates the radiator has sufficient fluid. Checking the radiator by opening the cap is a secondary means but the level may vary by temperature.
A common fan delay relay works by a small thermal coil contained within it. Upon application of the low-voltage control signal, usually 24 v, the coil begins to heat up and after a pre-determined amount of time, will cause the primary contacts to close. This allows the furnace to fire up and warm the heat exchanger prior to the circulation fan coming on. At the end of the heating cycle, the control voltage is removed and again, after a period of time, the thermal coil will cool down, opening the primary contacts and shutting off the circulation fan. This ensures an adequate flow of air over the heat exchanger after the burner is extinguished, purging the system of any remaining heated air. Even though it may contain a thermal circuit, it essentially is still a mechanical relay and thus subject contact stick, mechanical damage, etc. Many of them have been replaced with a solid-state relay and control/ delay circuitry.
