I use a hot plate with a pan of turbine oil to heat the sender unit. (turbine oil won't burn and it won't boil at 230 degrees but water will get you in the ball park). Some jumper leads and an old Ford/KS gauge that I know still works along with a 6-volt power source will do the job. I use an infrared thermometer to check the temps. A person can do it right next to the car if they have long enough jumper leads.
