get a new fan switch and thermostat....also consider a second fan switch

Check in this order

1) Correct Oil then,
2) Change Oil Presure Switch, if still no good,
3) Check oil pump pressure, if still no joy, then the engine is more than likely fubared!

If it isn't the switch, or the wrong/old oil then personally if it is running ok and only doing this at idle when hot I would just keep using it, otherwise it's a engine strip needed.
What is the idle speed, as if too low this will aggravate the light.

what oil are you using?

could be a number of things

when its at idle; is the engine noisy? does it sound healthy?

check what everyone else has mentioned, plus check the oil pick up pipe; i've seen these get blocked before and cause oil pressure problems

luke_rsfesta

engine sounds very healthy and doesnt idle too low,gona do an oil change tomorrow cus i think thats the quickest and easiest 1st

luke_rsfesta

noticed tody that its not boosting past 5psi,and is capable of up to 20,not sure how to adjust it??

luke_rsfesta

its 10w 40 oil at the mo by the way

luke_rsfesta

its sorted changed the oil for 10w 50 and put new oil pressure switch on and its all good now thnx guys

I will say, too late now tho, use the cossie switch as it will come on at a higher pressure meaning you will be less likley to cause damage to the engine if something were to happen!
