I have a WD45. Been chasing a weird problem since I bought this tractor this summer. The radiator loses antifreeze out the overflow tube but only does it after putting a load on it like after plowing or disking. Won't do it while brushhogging or othe light work. Has a new 8 PSI cap and new temp gauge from Steiner Tractor. The neck in the radiator looks fine where the cap seats. According to the gauge it doesn't even run at normal temp until it's loaded and even then it's still in the green area and never overheats. Have flushed the cooling system and replaced with 3 1/2 gallons of fresh 60% mix. It had head work done on it before I bought it and runs fine. I havn't checked the thermostat, could a missing thermostat cause this? Anyone know of a radiator pressure testor that will work on this tractor?
Thanks.
Thanks.
