hi guys


since i bought the car and its the same as is now.. i dont really know if i am having any probs in the coolant, but when i compared with my freinds Z's, i noticed that the other friends Z's have the heating needle just above the min.

also sometime when i push the car the heat endicator goes abit higher ( just like the blue line and then goes back to normal)

the yellow line endicates how my other two friends z's shows:





and btw all our z's Are stock, and the avarage temp outside is 40C, but same issue was on winter time.

 

mine is always at the same point...
haven't changed coolant in 10k miles.. should probably do it sometime soon..
yellow line seems too low.. I think it sits more in the middle.. more like the blue line constantly...

 

Out of the three lines you have in your picture, the top line seems the most normal, after the engine has warmed up. The bottom yellow line seems way to low for a warmed up engine...

 

yep, tops normal

 

I've never seen the needle fluctuate. Mine stays in the middle no matter what, what time of the year, or how hard I'm driving. Sorry, don't know what to tell ya.

 

Mine stays in the middle once heated, just like yours. Not sure why theres would be that low unless they were just warming up.
