Coolant System

[Exitium]

I have an 07 Corolla with 32,428 miles on it its 44 months old I live in an area of the country where the winters are very cold snowy and the summers are very hot and humid. I was wondering in your opinion should I get the cooling system flushed this year its not a scheduled maintenance requirement not until 100,000 miles but I thought it might help the radiator last longer. My last car was an 01 Jeep Wrangler and after 5 years the radiator rusted through the dealer told me if I had gotten a regular flush that would not have happened what do you think about that with Toyota?
Thanks.

If you haven't noticed any detioration of the cooling systems performance, then I wouldn't worry too much about leaving it in for another year or two. I had mine flushed at almost 100K.

It certainly wouldn't hurt, but it isn't necessary, but I agree with PhatRoyale, if you do not notice any significant deteration, let it go. The coolant that is in there is designed to last 100k.
