Just bought a 3330 V 2003 or 04 about 2900 hours driving it home the thermostat went upto 3/4 hot so I pulled over and parked it to cool down but won't start after an hours parking so drove it to my place next morning the coolant was little low I topped up before driving this time thermostat was 1/2 hot and stayed steady there, It was used by the previous owner to trim his vineyard and had a trimmer in the front so there was a lot of dust in the front I washed the radiator for clogging but not sure if that would work. Any ideas ? Would appreciate the feedback and also any other important info, Thanks
