2013 GTR 215 Overheating

[dannym]

Hi,
Twice I've got an overheating alarm, the engine and thermometer symbol, and goes into limp mode.
So I turn it off and turn it right back on and it goes away. I thought that was odd since if it was overheating it should still be hot. This only happens when I go over 50mph. If I'm in ECO mode it's ok.
I flushed the exhaust system after the first time.

How do I know if it's a false alarm or not? The dash doesn't show engine temperature.

Also I just rebuilt the supercharger but I don't see how that would have anything to do with a high temperature alarm. except if the coolant level is too low, I lost a lot when I pulled the t'stat out for access. The container is full and the level isn't dropping. How do I know if there is enough coolant?

Any help would be appreciated!

Thanks

The ic, may be plugged up or partially restricted. May have to flush it or replace it.

Check the pump

The manual says if the IC is clogged then the exhaust temperature will go down.

I'm kind of leaning away from it being the IC though I may just go ahead and do a pressure test on it.

The Troubleshooting Engine Overheating says:
1- Low Coolant Level.
2- Air in cooling system.
3- Thermostat defective.
4- Water Pump Failure.
5- Water Temp sensor defective.
6- Ride plate or hose damage.
7- Exhausted system clogged.
8- Internal passage blocked in cooling system.

So the question is which one would cause a high temperature going over 50mph but not under AND come in after the Supercharger rebuild??

I admit I probably removed more than I had to when I rebuilt the supercharger.
I disconnected he muffler and pushed it back. I removed the coolant temp sensor that's right above the supercharger. which caused coolant loss.
I flushed the IC again this time with the Pressure cap off. disconnected the hose from the tank and bled the air out and only got a few small bubbles.

I think I'm going to pull the muffler out.

Also is there a way for me to get fault codes from the computer?

Thanks!

If the ic is restricted then it won't flow enough water to cool the exaust, I'm saying I had that problem and changed the ic and the problem was gone. Same high speed overheat, just like you. Anyway we can only tell you what our experience is and you can do what you like.

Thanks, I appreciate your help but I don’t have $320 to spend on a new IC.
is there any way to test it?
it looks like there’s pretty good flow when I flush it.

What you could do is bypass it and see if you still have the problem. Hook the main hose going to the i/c directly to the exaust, manifold. I would not drive it real hard since the ic will not be cooling the air. But you should be able to test it enough to see if you still have the problem.

There are two separate cooling systems one for the engine block and one for the intercooler and exhaust system. If the engine is overheating then the list above applies. If the exhaust is overheating then I would check:

1 - Screen in pump.
2 - Blocked intercooler.
3 - Blocked water passages in exhaust manifold.
4 - Blocked water passages in J pipe where it empties into the water box.

I disconnected both hoses to the IC and put a garden hose on it.
the water flushed through the IC as fast as the hose could put it in.
the water cane out clear with no debris st all. I think I can say with 100% confidence that the IC is not plugged or restricted.
I had it back on the water today. Ran it to 50mph and got code PO217.
ran it for 1/2 hour and tried again. Thus time at full throttle, 65mph, and no alarm.

what is this alarm for? Some people say it’s engine some say it’s air intake?

Also, Can I use CLR on the ride plate?

[dannym]

Is the PO217 code for the engine, exhaust or both?
