MV8 5000mpi- where to add antifreeze?

[npress]

Getting ready to winterize myself this year. The Ilmor manual has nice pics of location of knock sensors and drain plugs.
There are no diagrams or pictures of how to add antifreeze through open cooled system.

Does anyone have pics or diagram of the exhaust feeder hoses and and thermostat hose ends?
The instructions are 1. Close water pick-up seacock
2. Fill engine block and heads from thermostat housing (feeder hoses)
3. Fill exhaust manifolds by removing thermostat hose ends
4. Fill sea strainer
5. Reinstall hoses

Thanks for any info to help make sure I have the correct hoses.

Pull the plugs shown in the owner's manual. Fill a 5 gallon bucket with pink rv antifreeze. Then pull the hose off the thru hull, pop that into the bucket. Run it till Bucket is empty. Dump a gallon or more into each ballast tank.

I just paid my dealer to do this to insure my warranty is good to go. I have been doing it on my boats and jet skis for 13 years. Each unit is a little different, but no biggie.

I will most likely do my own next year I feel like it cost me way too much over 800.

With this method don’t forget to run the engine to operating temp so the thermostat is open, then put raw water intake hose in bucket with RV antifreeze.

Good call, I usually run the boat 10 minutes, then change oil then 5-10 more then winterize.

running the engine is not required if the block is drained before adding the antifreeze. The cold antifreeze will close the Tstat pretty quick anyways.
