Find radiator and coolant reservoir caps at Natrad
Need a replacement coolant cap? Ask a radiator technician for the right radiator cap for your car.
The radiator cap is an important part that maintains the correct cooling system pressure. An old radiator cap may not hold the same pressure as a brand new one. So when your vehicle’s thermostat is replaced, it’s a good time to get a new radiator cap installed too.
If coolant pressure is too low, the coolant may boil at unacceptable temperatures. If the pressure is too high, the system can be damaged, and the vehicle may overheat. Replacing the radiator cap every few years will prevent malfunction.

Natrad supply radiator caps from 4 psi to 30 psi. So check the manufacturer’s specifications for your vehicle or ask a specialist for the correct coolant cap.
You should check your coolant when you check your oil level. If you have to top up the coolant often, or you suspect a problem, take your car into Natrad. Your local Natrad can carry out a free vehicle cooling system inspection to identify the cause of the problem.
Yes, replacing the radiator cap is as easy as unscrewing the old cap and screwing on a new one. Never attempt to unscrew a coolant cap while the car is hot, as there is a risk of being burnt by the hot coolant. Make sure the replacement cap has the same specifications as the original.
We have radiator caps with brass pin and lever or a nylon pin and lever. These safety lever caps are suitable for performance and mining applications to prevent scalding and burns when the cap is removed.
Our Heavy Duty Cooling stores stock mine safe caps and adaptors required on most Australian mine sites to prevent scalding injuries.
