CAN YOU VERIFY THE FAN(S) ARE WORKING?

RUNNING 50/5070/30COOLANT/WATER RATIO. IN A CLEAN (FLUSHED) SYSTEM?

I MEAN, THE RATIO MIXED OUTSIDE OF THE CAR AND POURED IN. NOT JUST POUR IN COOLANT AND THEN ADD WATER WITH NO IDEA WHAT THE RATIO FINALLY COMES OUT TO BE

I CHANGE MY THERMOSTATS ONCE A YEAR NEED IT OR NOT (MY PERSONAL PREFERENCE)----BOTH OF MY JEEPS HAVE NOW HAD 22 'STATS, SINCE I GOT 'EM IN 1991

IT MAY BE NORMAL TO HAVE A SLIGHT RISE IN TEMPIS IT WAY UP THERE?

THE TEMPERATURE SENDING UNIT MAY ALSO NOT BE READING EXACT. COULD BE DEFECTIVE

I USE AN INFRARED THERMOMETER TO CHECK THE TEMP OF MY WATER OUTLET(THIS TEMP SHOULD BE CLOSE TO THE THERMOSTAT'S TEMP RATING)---TOP RADIATOR HOSE---TOP OF THE RADIATOR---MIDDLE OF THE RADIATOR----BOTTOM OUTLET OF THE RADIATORTO SEE WHAT THE TEMPERATURE IS "AS IT LEAVES THE MOTOR"---"ALONG THE WAY", AND "WHEN IT RETURNS"

I COMPARED MY GUN W/ MY FRIENDS EXPENSIVE ONETHEY SEEM TO READ CLOSEMINE CAME FROM "AUTOZONE" AND WAS A LITTLE MORE THAN $30. IT AIN'T GOTTA PASS THE NATIONAL BUREAU OF STANDARDS STANDARDS FOR THIS TESTING !

MIGHT BE TIME TO TREAT IT TO A NEW RADIATOR CAP
