What pressure radiator cap should I use?
Use one with the psi rating that the rest of your cooling system was designed for. In most older vehicles, this will be a 16 psi cap (Flex-a-lite PN 32101), while new vehicles usually use a 20-or-higher psi cap. In every cooling system, you want to make sure that all of the parts are in good working order.
Are all radiator caps the same?
Radiator caps can come in all shapes and sizes unique to your car’s radiator. A malfunctioning radiator cap may cause the engine to overheat at lower temperatures or prevent the coolant from returning to the engine.
Are radiator caps standard size?
They are mostly standard sizes, but some of the older ones were taller than later ones. If you have the stock radiator, then you want the stock pressure cap. Higher pressure will tear the radiator apart.
What do the numbers on a radiator cap mean?
The numbers on the cap relate to the pressure at which the cap will allow the coolant to flow out of the radiator and into the overflow bottle. Most radiator pressure caps keep the system pressure at 16 PSI so the engine coolant can get considerably hotter without the fear that it will boil off.
What is the difference between 9 and 1.1 radiator cap?
Most probably the engine operate at a higher temperature therefor it needs the cap to be in 1.1 bar so the boiling point of your coolant would increase. 0.9 would decrease your coolant boiling point, and you lose out more coolant once the relieve valve in the cap release vapor to your reserve tank.
What happens if radiator cap pressure is too high?
High – Pressure Radiator Cap Unchecked high pressure could cause damage to the radiator, heater core, hoses or water pump seal. The pressure cap also prevents radiator hoses and tanks from collapsing. As the engine cools it causes a vacuum in the cooling system.
Which is the best radiator cap?

What is the preferred mix for the radiator?
Under normal conditions, a 50/50 mix of water and coolant is preferred for most vehicles. If the day is extremely hot or cold, a higher proportion of coolant /antifreeze may be necessary.
Should I replace my radiator cap?
If your cap fails any part of the test, it should be replaced. If you see rust inside the cap, or have any other reason to doubt the condition of your radiator cap, replace it. It is such an inexpensive part, and so important to your engine’s health, that there’s no reason not to replace it with a new one.
Is radiator cap Same as coolant?
The radiator cap is the gatekeeper of the cooling system. The cooling system uses pressurized coolant (also known as antifreeze ) to take accumulated heat away from the engine. Having a functional radiator cap is critical to this process, as it maintains the proper amount of pressure.
Can I drive without radiator cap?
You can drive without a radiator cap forever, so long as you add coolant before taking the car out. If you drive without the coolant cap for any length of time when the engine gets up to temp it will boil over out of the reservoir.
What is a 0.9 radiator cap?
What does 0.9 radiator cap mean? 1) Radiator cap it a control valve that raises the boiling temperature point of the car cooling liquid keeping the coolant in liquid form under higher operating temperature. 4) 0.9 Bar (13 lbs) Cap: Valve open at 100 degC.
Should radiator valves be fully open?
Begin by turning off your heating system and allowing it to cool completely. 2. Once the system has cooled, it is important to bleed the radiators in order to remove any trapped air which can result in uneven heat distribution in the radiator. You should also fully open the TRVs (thermostatic radiator valves ).
What number should your radiator be on?
As a rule of thumb most guidelines recommend heating your home to 70F (21C) and bedroom temperatures should be kept a little cooler to around 64F (18C). For most people this temperature will be comfortable, but if it feels a little hot (or alternatively cold) then the temperature can be adjusted from this baseline.
What does 1.1 bar mean?
A standard 1.1 bar cap adds 48 degrees to the boiling point of either fluid. So the coolant in your car will not actually boil until ~260 degrees, or ~271 degrees if it has antifreeze mixed in.
