- Less than 3 months but I don´t trust this radiator cap, I had to modify it in order to be able to use it, I need a new one.
- I replaced it because the previous one wasn´t holding any pressure, this one does hold pressure but I think it has problems with the upper seal and this causes the coolant to not return from the overflow tank into the radiator when the engine is cold.
Coolant not returning from overflow/reservoir tank into the radiator when the engine is cold likely is caused by mal-functioning check valve within the cap .......
in this scenario your engine cooling system is operating under perfectly normal conditions as long as full coolant level at cold is satisfied before every start, granted with absence of thermostat.
OP, as long as there is full coolant level before every start, you may get away with immediate replacements of cap (and thermostat)in your context until such time when you're ready.
