Hi guys,

On my Malibu I always drained the block then ran Pink RV Antifreeze through it and left it in there for the winter.

The LTR is Differetn from the LT-1 correct? From what I've read here in the forums, the LT-1 has aluminum heads which don't like the pink antifreeze, but it seems like the LTR will be fine with the Pink Antifreeze in it......

thoughts?:confused:

thanks,

bump..... I'm guessing most of you have the good fortune of not having to winterize?...... My jealousy -> :rant:

Is Pink anyfreeze ok to use in the LTR?

Anyone?:worthy:

Why don't you just drain the engine? I used to pump anti-freeze but draining is much easier and faster.

I guess I'm scared to DEATH of having water somewhere in the engine causing a crack :eek3:.....

On mu BU, I actually drain the block, impeller hoses, and the tranny hoses, the I start it back up and fog it while I'm sucking antifreeze in.....

Do what you are doing above ^^^^^^ As for antifreeze I don't know but am pretty sure pink is ok in the LTR. Ask JimN for clarificaiton.
