L99 engine bock coolant drain plugs location
I'm getting ready to do a coolant change on my 2014 ss and plan on draining the block from the drain plugs. Does anyone know where they are located on the L99 engine?

I did get most of it and here's how I did it if anyone is interested.
1. drained radiator 2. refilled radiator short of top hose level. 3. pulled heater hoses off nipples on block. ( my thermostat is on lower radiator hose with heater hoses on block side of thermostat).this drained much of the block. 4. used very low air pressure to expel coolant from heater core. 5. refilled core through inlet hose until it ran out return hose. 6. pulled upper radiator hose and filled block through it until it ran out of heater nipple.( I could hear the block bubbling as I poured it in) 7. attached all hoses and topped off radiator. 8. fast idled with heater on high until bubbles stopped. capped it off and let it cool. 9. rechecked radiator level and bam, done. 9 qts. out, 9 qts. in. This may not be the best way, but it beats flushing with water and draining several times. |
