Hey guys, Just wondering if this is normal. I have a 2008 G35 Journey and when 25 degrees outside in traffic moving at about 10 - 15 mph for 15 minutes, my temp gauge is maxed. If I'm sitting in a drive thru for a long time, I have the same issue. Is this normal?

 

Also, don't know if related. When warming up car in morning, I'll turn the heat on and let it idle for 3 - 5 minutes. Heat is not hot at all, but warm. Then when I start to move, literally out of the driveway the air is then hot. So it seems that the heat is only coming out hot when the car is moving.

 

^ the warm heat in initial start up is normal but the temp MAXin out is NOT normal at all even in sitting traffic and that too at only 25deg(C or F either way) get it checked out under warranty asap before u get any warpage

 

Temp gauge maxed out and not much heat coming out of the vents usually means you're really low on coolant.... hope nothing was damaged. Good Luck

 

Hey Tom, Thanks for the reply. The temp gauge would bounce back down a little after maxing. And there was HOT air coming out of the vents at that time. I checked the coolant and it was full.

Two separtate issues that I think are related. I was just stating that after the car is sitting at night and I go to warm up the car in the morning and crank the heat, only warm air comes out and then hot air comes out as the car is moving. The engine is already at the normal operating temp before I start moving.

 

my guess would be a broken thermostat.

 

My temp gauge never moves once fully warmed up.... no matter temp. or slow. or high speed running,,

 

^ thats how it should be, the OP has some problem for sure but its been a while since he reported back so he might have had it fixed.

 

Kool,,, can i ask u about your foot illumination?? Is it from the Infinit acc. catalog??? how hard to install??? i would like to augment the upper ambiance lighting in the car....

 

have you checked your fan? since this only happens to you at low speed, which engine mainly use fan to cool at that time.

 

hey triton just saw this, not sure if i ever answered this in a PM or not but if i didnt then i got the foot illum from japanparts i think but you can get it from any dealership really especially riverside. The install instructions come iwth it and its easy but takes a bit of time.

@dota, i THINK he figured it out which is why he never wrote back...

 

Hey guys - thanks for all the replies! I've been keeping an eye on it and it has not happened since. Maybe a fluke?

 

^ glad to hear it but it cant be a fluke, maybe the thermostat or radiator cap seal got stuck then or maybe cause of air in the system... either way it will be hard to know unless it happens next time(hope it doesnt!)
