2010 w ZR409 have any water in motor or just coolant?

Hey guys, Im in south texas and got pretty cold last night and was wondering if I should be worried about any water freezing and causing damage to engine. Normally doesn't get anywhere near this cold so I normally dont winterize or at least drain any water since I figured w the coolant it would be fine. Thanks in advance

It should be a partial closed cool engine (heater has coolant in it)...so yes, you need to drain the water out of rest of system. General rule of thumb I have heard (tho I wont risk this), is 24 degrees for 24hrs.

If you can't drain...put an ignition protected heater in engine bay. It had been usually cold here too and I have same engine in my 2014, so assume it's the same as mine. For sure you have water in it tho, none are filled with only coolant.

throw a spacer heater in there at its lowest setting. Ignition protect heater is great, but they are expensive. a household heater will work fine for a few days. i would purge the fresh water out of the exhaust, heat exchanger and the others if able. may wanna pick up a gallon of cheap RV coolant at an autoparts store when you do it.

i'm up in austin, but given the freezes we've already had, i figure that we won't be surfing until march.

I would suggest maybe sharing the temp range you anticipate.

I winterized mine and STILL have a small heater in it since its been getting to 8 degrees here at night for almost a week. I know that is nothing in some states, but unusually cold for NC and I am too paranoid to chance it even tho I know mine would be ok since I drained all water and then put RV AF in system. I know I am wasting electricity.

Its been in the mid to high 30s for the last week but last night it got in the low 20s. Gonna go by and check on it this weekend. How would I know if anything happened? What and where should I be looking? Thanks

Very hard to see issues with naked eye, but most common I would think, would be a crack in block, or exhaust riser, or possible at plastic strainer if you have one. Dont think you are likely to see anything obvious, just have to go forward carefully next time you run it and watch temps and engine compartment very carefully (maybe others have suggestions about that too). Hopefully you got lucky, tho low 20's can definately do it. If it was inside building, its usually a bit warmer in there...and perhaps a bit warmer in the engine compartment. Hopefully you will have no issues but I would take precautions moving forward and drain or put in heater during cold spells. Will only take you 10-15mins to drain the water cause the issues happen when it freezes, expands and has nowhere to go, so it breaks something. If water has room to expand when it freezes cause you drained most of it, you wont have an issue with breaking, but water can cause corrosion sitting there too which is why anti-freeze is recommended by some.

Well we will see. Thanks again for the help.
