Hi everyone,
My upper radiator hose gets firm when the engine reaches operating temperature. It is firm but not hard. It is still squeezable to some extent (about 4 to 5 centimeters).
I am worried about this. Does my cooling system have higher than normal pressure?
Also worth mentioning:
1 - My car doesn't lose any coolant
2 - The temperate gauge is always within normal range
3 - No overheating issues
4 - No air in the system
5 - Engine runs fine and pulls nicely
6 - Thermostat runs fine
7 - No oil in coolant or coolant in oil
8 - No bubbles in coolant at the radiator filler neck whether the engine is cold or hot
9 - Radiator cap was replaced 2 years ago
The engine is XU7JP4 LFY.
So, why my upper radiator hose is not soft to the touch? Is my headgasket blown? Should I tear the engine apart?
