what temp thermastat shuold i have in a chevy 1500 2-wheel drive 4.3litre
OE or Original Equipment used a 195 degree thermostat.
And be sure to test your thermostat before installing it by putting it in a pot of water with a thermometer to see how hot the water is before the T-start opens up. Its not uncommon for them to open up at the wrong temp.
