Ford 1300 Problem

[deano29]

Having problems with my older Ford 1300 with overheating. It runs fine on its own but once I try operating my 'Weed Badger' or rototiller it doesn't seem to have enough juice and wants to quit on me. Any ideas of what to look for or check. Already looked over the injectors and changed the filter. Thanks for the help

Check temps on radiator top and bottom tank with infra-red thermometer or equivalent. Normal temp is about 200F on top not sure how much temp drop but bottom tank should be cooler. Check fan belt for tension(1/2 inch deflection). When engine NOT running grab fan and see if it can be rotated easily. Check radiator for obstructions in the air fins and good flow through the radiator
