My factory guage never reads above middle which is why I got the Scan guage. I am usually 190-195. Before I did my T-stat and radiator I had hit 230 once or twice which to me is way to high and verge of overheating. I have yet to fond a Toyota reference or technician that can tell me what the range rating was set at on the factory guage.
I hooked up my Scan Gauge II, and it shows from 190 to 198 for a temperature. Is this about right? Is there a normal range for high load situations? For example, if I get up to 215 am I headed for trouble, or is that okay?
Thanks in advance,
Richard
i have had my scan gauge hooked up for about a week now and my water hits 207 and stays there. it has been in the high 60's to almost 90 and no change, once it did hit 208 when i really got into it merging with traffic.
