If the thermostat as failed open so engine is running cool you can add an inline thermostat in the top hose, this should take no longer than 40 minutes and cost you at the most £7, if you go the way of a alloy inline thremostat this is going to cost your in the reagion of £60 and again about 40 minutes of your time Arctic.

The job is tricky so 2 1/2 hours doesn't sound too far fetched. The part seems to be £30 to £40 on ebay. The hard part is the hose clip on one of the pipes. OK if your pliers sty clipped on, a complete pig if they slip off.
