Perkins 4.236M Radiator Cap

[Underdog]

Hi,
I am hoping someone can give me an idea where to locate an OEM or a suitable alternative for a radiator cap for a 4.236M lowline engine. I believe a Fordson Major tractor radiator cap will work, but am unsure of the model tractor or P/N for that.
Any Ideas?

I have seen caps for this engine with settings of 4, 7, and 11 lbs. Makes a considerable difference in the boiling point of the coolant most suitable for your engine use.

Hi,
Radiator caps for the 4.236M are available from parts4engines.com
Give them your engine number if possible
I have a 1978 lowline version and the manual shows a 7 for my radiator cap
Check yours by engine number and cros ref to the manuals if possible

These guys (parts4engines.com) have a lot of parts for the engine
Also try ASAP supplies in UK

Failing that, go looking for your nearest Massey Ferguson dealer/garage/mechanic. These guys may have it

According to the manual, the proper pressure cap is rated 7 psi.

Yup, got all that. Thanks for the input. The Fordson major is only rated at 4psi. The engine was running with one fitted when I bought the boat, but it fell apart and I refitted the original, but it is looking a bit tired now. Have sourced one in the Uk, so should be ok.
