my coach is running a little bit hotter than normal. I have to admit I haven't cleaned the radiator yet and this weekend will happen but I was also thinking that this could be because of the coolant being too old? I've never had any issues with the exitisting coolant but I don't know if I have to replenish SCA's or if my coach even has an SCA filter for coolant. I have to take a close look this weekend for this but if anybody knows this from the top of their head it will be highly appreciated if you can tell me if I should look for such a filter or not.

Also, I have no idea what coolant my coach has so I was going to do a complete flush and refill and I was in between SCA coolant and OAT coolant for an 8V92 should I have any preference? I have several bottles of SCA already so I was inclined to buy more of those and do the refill but I can also buy the Final Charge one and replace it with that one if it is better.

Thanks for any help on this.
