I have an AU mach III falcon ute and have noticed a vibration in the engine bay when accelerating at 60 km/ h and when the car was idling the thermostat went to full Hot. Just happened an hour ago.

HelloSo engine vibration is usually a misfire or a broken engine mount.If you get someone to rev it when stationary does the engine move excessively?
I have just started the engine and reved it for thirty seconds and there is no movement from the engine, i think this is an issue with the cooling system
Does it run smoothly when you keep the revs steady?
yes the engine is running smoothly
Do both top and bottom radiator hoses feel warm?
yes they are both hot to touch and the car hasnt been driven since 45mins ago, i bought the car 2 weeks ago from a lvd, the engine bay is spotless and all fluid levels are at maximum
Well there is really only the thermostat which would prevent the cooling system function correctly, assuming the pump and fan etc are all working. However this really will not induce a vibration.If you can not feel the vibration when stationary its more likely to be the tailshaft or an engine or transmission mount or a wheel balance. If the engine is running smoothly this also indicates a driveshaft issue rather than the engine. A basic test to try is to mark the shaft and diff flange then undo and rotate the shaft then reattach the shaft, if the vibration gets worse you will need to get it rebalanced. Unless the engine is overheating I would not be concerned with the cooling system.
