Is it ever normal for the needle to pass N?
Hello everyone!
I haven't been posting much because my X type got rear ended by an uninsured driver and there was a little back and forth with my insurance company, but finally the car is getting fixed and will be ready this week. (I am surprised it wasn't totaled considering the rear bumper was destroyed and the trunk was compromised, along with some other panels)
But to the issue at hand:
Before the accident it had been getting up to 105 degrees in Houston, and I noticed that a couple of times after driving in the hot weather, turning of the car (like say to go into the grocery store for a few minutes) and then turning it back on, the needle would go beyond N with the red light on when I re started the car but then immediately go back to N or below.
Is this normal? I don't think I have ever seen this with this car. Coolant reservoir was replaced a week before the accident due to a tiny leak, so there was no water leak issue.
Thanks

Hey Mark. Sorry to hear that your kitty got goosed, but glad it's back on the road.
When you replaced the coolant reservoir, did you purge all the air from the coolant system?

Spike, I have since found that you don't need to "burp the kitty". Simply filling up the system, letting it get up to temp and cool back down a few times will get all the air out of the system. Getting the engine up in RPMs will help push any air out that much quicker once the engine is warm.

Thanks so much for both of your replies.
So the veredict is that under no driving condition the needle is to pass N, correct?
Please keep in mind I mentioned that I had been driving in 100+ weather, I shut the car down to run a errand, then restarted, and upon restart the needle went very slightly above N only briefly like 20 seconds, and then came back down.
I think the fans are probably the direction I need to go in.

IMO...I don't think anything is abnormal...after a run and shutdown..the engine is still hotter than f.ck Breckinridge and heat soaks the coolant ..so a start-up soon afterwards will reflect a very hot engine still and the pump circulating the coolant brings it back into normal range temps again....Fans could be an issue, I believe they should run a little while after you shut off the engine for that reason.
