Water change?

[Big Al]

Hi,
 
I just noticed from a welcome message that Mir made today,  that a regular water change is beneficial for our lovely rotaries. I know about topping up with distilled water but not much more.
So I\'d really appreciate any guidance regarding water change frequency and where to find the drain plug??
 
Cheers, Al.

Hi Mate

Indeed water change is beneficial. However, you don\'t change water as often as an oil. I read a thread by Aron Cake (American Engine Builder) and also read loads of info on Aussie Rotary site. If I am not mistaken, every 1 to 2 years water change is recommended. I don\'t have a clearly info to hand as I am chilling at the moment in my bed using my Ipad:):King, but certainly I can dig an info out for you. If, again, I am not mistaken, the conclusion of the water changing discussion I read were pointing towards the bad functioning of the properties in an old Radiator water, and how it affects the engines. So, in nutshell, it\'s the properties in the water which gives up with the passage of time and does not kill the heat efficiently.

I hope the info would help.

Cheers
Mir

The other water drainage plug is on the side of the engine near the spark plug area. I don\'t have a 13b anymore but I am sure that the water drainage plug is on the plugs side of the engine-either in the intermediate iron plate or rear iron plate. You can\'t miss it if you look there carefully.

Answer from RotaryEvolution:

if the system hasn\'t been kept well in the past i would recommend once a year for a few years to get much of the junk out of the system. if it has been well maintained then i would recommend every other year to drain and refill it with 50/50 coolant/distilled water.

Re: Question

Answer from Hayward Rotary:

It depends on the coolant as you can get 5 year or 2 year or 3 year.
We allways use the 5 year antifreeze as its top quality and also perfect for the mix of iron and ally in the engine.It shouldnt need changing for the 5 years really.

"There is a maintenance schedule in the FSM for the year of your vehicle. Every year seems excessive to me unless you store the car over the winter. Two years should be fine. 30/70 mix of ethylene glycol and water unless you see very cold temps in which case it should be 50/50."
