I have a 1995 Ford Bronco 5.0 with 143000 miles. Recently I added a temperature gauge so there are two sending units, one for the gauge and the other for the dash unit, I live in New England so the other day when the outside temp was 30 degrees the truck would not warm up to more than 170. I changed the thermostat, radiator cap and did a pressure test on the cooling system. I've checked the out let hose temp with an infrared temp gun and it reads 160. Why won't it get up to temp with a 195 thermostat.
