Did the exhaust gas test tonight and the liquid did not change color - no exhaust gas in the radiator. Basically the engine starts and runs smoothly and slowly heats up - about 15 minutes to get up to 190F. I tried blowing addition air through the radiator with a shop vac. This slowed how fast it heated up but still hit 190F in 20 minutes. I am using a thermometer in the radiator to check the temp.
Would like suggestions on what to try next. Add 160F thermostats? Remove the radiator and try to find a radiator shop? Buy a new radiator? Replace the water pumps - they appear to be new?
