Hi 3050RPM, I presume you are in the states from your estimate quoted in dollars$$$$, nice to hear from someone across the atlantic.
Hose ordered today so should be with me tomorrow afternoon, £10 so not too expensive at this point, will consider replacing other hoses after trying the car with new hose fitted. On inspection of the burst pipe I personally wouldn't say it is aged, no obvious signs of wear, doesn't look cracked or brittle.
Although I said the fan spins there may be resistance so not so sure it is freewheeling, I guess this would become evident when the car is started again, if it starts, and if the fan spins whilst car running then I assume the water pump is OK.
I shall remove the thermostat and test this too, over pan of boiling hot water.
How do I flush the cooling system, is it done and one complete system or are separate parts flushed seaprately? Hose pipe down the radiator or coolant top-up tank? Guidance here greatly appreciated!
Thanks again for your advice.
