What connects to the radiator hose?
The upper radiator hose is connected to the thermostat housing and to the radiator. From the bottom of the radiator, is the lower radiator hose that is directed to the water pump. Both the upper and lower radiator hoses are the largest hoses in the cooling system connected to the engine.
Which radiator hose wears first?
The upper radiator hose fails more often than any other hose, followed by the water pump bypass hose (if your vehicle is so equipped), and the outlet heater hose from the engine to the heater core. Experts recommend, however, that all hoses be replaced at least every four years or when one fails.
Which way does coolant flow through a radiator?
The coolant flows through the thin tubes that make up the core of the radiator and is cooled by the air flow through the radiator. From there, it flows out of the radiator, through the lower radiator hose and back to the water pump.
Do I need a spring in my lower radiator hose?
We’re going to get arguments on this one, especially from hose manufacturers, but all molded lower radiator hoses should have an anti-collapse spring. The hose collapses causing coolant starvation and overheating on the open road at high rpm. You get back in to town and temperatures return to normal.
Where do the hoses connect to the radiator?
On the other hand my new case is so small, that mounted right side up, the pump sits slightly above where the hoses connect to the rad, meaning that air could get into the pump anyway (although it would be more difficult).
Why is my lower radiator hose Cold instead of hot?
If you have a problem with your coolant temperature and realize that the lower radiator hose is cold instead of hot, you could be experiencing problems with the coolant system that needs to get fixed. You will need to look at the various parts that influence the radiator temperature to properly diagnose a lower radiator hose cold problem.
Do you put fans on top or bottom of radiator?
I never had the particular AIO, but regardless of positioning, you can help it out a bit yourself. While running, gently take hold and pinch the tubing just twice, really fast, minimum pressure, and let go. Repeat on the return line. I have my 280 radiator with 2 fans on the bottom of the case and use a AIO CPU Kraken.
Where is the cooling fan located on a Miata?
The base Miata has one fan, mounted on the left (looking forward) side of the radiator, called the Radiator Cooling Fan. The Radiator Cooling Fan motor should use 5.3 – 6.5 Amps.
