My friends 560 sec is running a little warmer then we
would like it to.We replaced the t-stat the spring was
broken inside ,refilled the radiator with a-freeze
roadtested it but still no good.It stays around 90-100c.
The radiator was replaced 2 yrs. ago.The viscus fan appear's
to be working properly.The aux. fan is also working ok.
If anyone outthere has seen this please give me a shout".
