Coolant replacement

[jerry davis]

Anyone know the actual volume of coolant needed for the 2005 ISL 400 when you are replacing all the coolant? The manual says around 10 gallons. Was the original fluid ethylene or propylene glycol and how can you tell the difference?

Can you mix propylene an ethylene glycol?

When we replaced our radiator last week, the shop said they put in about 12 gallons, and that's what was on their bill. May be correct or not, but it's at least 10 gallons. After I ran the engine several short trips and got it good and warm, I added almost another gallon to get it back to full; suspect it had air in the lines, especially in the heater hoses.

Ours came with ethylene glycol (the greenish-yellow stuff). I think proplylene glycol is pink -- and supposed to be longer life. I use Prestone 50/50 pre-mix ethylene glycol/water to top off the tank. Supposedly you can use it to top off either type because it is supposed to mix. My radiator shop replaced the coolant when they changed the radiator with ethylene glycol and recommended the Prestone 50/50 premix to add to it.

Last change out I went with Fleetguard's ES Compleat™ EG. This is a high performance fully formulated Extended Life Ethylene Glycol
Antifreeze/Coolant.

In our 2002 I use exactly 11.75gal.

Excellent, thanks for the info.
