    Radiator flush

    New to this site, great forum! I have an 01 SS Camaro and need a coolant change with radiator flush.Are you guys doing this yourself or getting a shop to do it ? I had heard that the LT1 cars have a reverse flow coolant system. Do the LS1 cars have this same system? Once again, great site and keep on posting !

    I was told by the local Chevy dealer that radiator flushing was definetly a must after 36,000 miles, especially if your vehicle is starting to run a little hotter than usual, which is sometimes due to engine programmers and bolt ons. Case and point, my LS1 was running at a temp just below 210 consistently, but after my bolt ons, it ran at 210 and above. Anyhow, I will be going in for a radiator flush in the near future to see if it helps. I'll keep you posted.

    The LS1 is cooled block first...so no it's not reverse cooled like the LT1.

    It's wayyy cheaper to do as much on your car as possible....and it feels good to know it's your sweat and blood on your engine and not someone else's. A flush is easy anyway...just make sure you get all the air out of the system after the flush. Do a search and there should be some posts on how to do a flush also.

    A flush is always a good idea and doesn't hurt anything.

    Using any programmer/tuning software correctly won't raise enigine temps....if anything they'll drop from lowering the on/off temps for the low/high speed fans. Cheap bolt-ons like uncoated/unwrapped headers could raise the temp though. The stock temp gauge on 99-02 f-bods are only accurate to about 200*...after that it only shows a overheat condition. So if yours is showing a overheat condition i'd do a coolant pressure check when you do the flush....you can rent the pressure checker for free at any autozone.
