1.6 Radiator cap

Recommended Posts

Hello everyone,

My DR-Z 400 E is used only on off-road use, Enduro rides.

I think when th DR-Z is pushed to much, the coolant fluid b oils over.

I've noticed that the oem radiator cap only handles 1.1 of pressure.

I have found one, from Outlaw parts, that handles 1.6 of pressure.

Thinking on getting this 1.6 radiator cap, do you guys think it's wise do do it?

Will this 1.6 cap do any damage?

I don't know if it makes any difference, but the radiator hoses are no longer oem, are from Samco. Since i have them, the cooling has improved, but i think the 1.6 radiator cap will evem improve more.

Any ideas on this subject?

1.6 atm cap will work fine. KTM's use 1.8 and I saw an add for 2.0

Higher pressure cap does mot improve cooling but it does prevent coolant loss to a higher temperature. 50/50 coolant and 1 atm cap boils 265 deg F. Each psi of pressure raises the boil point about 3 deg. So 1.1 to 1.6 cap is 1/2 atm or about 7 psi. Should hold off boiling to around 285.
