What temp is radiator hose rated for?
Temperature range: -65°F to 350°F. Service: Low pressure coolant and heat connections in hostile engine environments.
Why is the top hose hot and the bottom hose cold?
Any idea why the top hose would be very hot while the bottom one ( and also the bottom of the radiator is cold while the top of it is hot). Its a new radiator by the way.

You may finally be forced to purchase a new radiator after performing this leak repairs. A cold lower radiator hose will cause an overheating problem. The cause of this varies with the main culprits being a leaked hose radiator pipe, a faulty thermostat or hindered coolant circulation.
Why is the bottom of my water pump cold?
The top hose is hot/pressurised but the bottom hose is stone cold. Thermostat has bern changed but the problem persists. I now have the water pump off and it looks ok? Any help welcome.

Is the bottom hose of an Audi hot or cold?
The car in question I a Audi 1.9 tdi. When you drive the car the temp rises and rises. The top hose is hot/pressurised but the bottom hose is stone cold. Thermostat has bern changed but the problem persists.
