likely normal Posted by Kevin K [Email] ![]() ![]() In Reply to: SPG running hot, Ben, Mon, 16 Jul 2001 10:07:26 Members do not see ads below this line. - Help Keep This Site Online - Signup |
normal is 2/3 (3/4 max) up on gage, fans come on, idling, ac off. normal running, ac off, 50% on gage with std 87C t-stat, 40% with optional 82C one.
C900 saab is unusual in that a linear gage is used, that changes directly with temp. most other oem gages will rise to a normal position and then doesn't move. That single position covers the 20F+ range of temps between t-stat open and fans on .... ie they don't indicate the normal cooling cycle as the C900 saab does. Many on this BB doen't understand this.
many suggest a lower temp fan switch, which does nothing for a healthy system except wear out the fans. it is a good temporary fix for a badly clogged radiator that causes temps to get near red before fans come on at idle, with oem fan-switch.
