AFTER YOU REACH OPERATING TEMPERATURE

AND I'M GUESSING YOU HAVE THE CORRECT TEMPERATURE THERMOSTAT INSTALLED (NOT COOLER THAN OEM)

STAND UP FRONT AND SEE IF ROARS, THEN CALMS DOWN, THEN IN A MINUTE OR SO, IT ROARS AGAIN (AND OVER AND OVER)

THIS MEANS IT'S WORKING RIGHT

RECKON YOU HAVE THE CORRECT CLUTCH?

WHERE'D YOU GET IT, DO YOU KNOW THE PART NUMBER?

I'VE SEEN "MUSICAL BOXES" PLAYED AT PARTS STORES MANY TIMES

THIS IS WHERE THE CUSTOMER HAS 5 BOXES OPEN, DESPERATELY LOOKING FOR A TWIN TO HIS OLD PART. ONCE IT'S FOUND, THE REST OF THE PARTS JUST GO BACK INTO ANY OLE BOX, THEN SHOVED BACK AT THE PARTS GUY.
