A radiator coolant flush is not a hard thing to do... Go to the store and buy the following:1. one gallon of antifreeze2. one can of radiator flush3. new thermostat with gasket4. new radiator cap1. Drain the radiator.2. put in the radiator flush.3. fill the radiator with plain water4. Run the engine per the directions on the radiator flush5. Drain the radiator6. Refill the radiator with plain water (add slowly if you didn't let the engine cool from previous run)7. Run the engine until at operating temperature8. Drain the radiator9. Replace the thermostat (make sure the bleed hole is at the top).10. Open the coolant bleeder bolt near the thermostat housing.11. Mix new coolant 50/50 (1/2 coolant with 1/2 demineralized water, not plain water!)12. slowly add new coolant to radiator until coolant comes out of bleeder bolt.13. Install new radiator cap.14. Check coolant level of coolant expansion tank and fill to spec.That's it! Now the question... why is the current coolant gooey? Your friend could have blown a head gasket and now the combustion gases are entering the coolant system! That's baaaad! You can check to a degree by removing the radiator cap and running the engine... expect to overflow a bit as the engine comes to operating temperature but look for bubbles in the water. There should be NONE! A foamy look or bubbles comes from combustion gases entering from a cracked head or blown head gasket. A shop can also check with a pressure tester or a device that checks the water for combustion byproducts.Good luck!
