Damn today as i will getting home from work...the damn Temp in my car went so high..I got the alert on the dash that the engine was hot..I pulled over and just turned off my car, then turned it right back on and the temp was normal..I was scared it was over heating, but it wasnt...that was strange, any idea what could have cause the sensor to go off!!

It's NOT the sensor. It is a small problem with the gauge cluster. There is a sticky here on that subject. My car does that too sometimes, then when the car gets moving the temp goes down. Same thing with the fuel gauge not going all the way to full on a fill up. Small shit. Right now I have a black spot on the odometer. Kinda like when a watch cracks and the liquid leaks out. Debating on taking the car in for warranty service or buying a new cluster and installing it myself.

this has happened to many people if you have access to a programmer just delete it ,if not try the battery cable,mine used to do that all the time after first tune(mail order) then i got my own HP tuners turned it off.the neg battery terminal and a 10mm wrench is your freind,the computer will relearn how you drive and with luck all will be fine.

I have thought about doing the same thing. Maybe a red or gray 05-06(slanted font) cluster swap?

**qwkgto** · 02-02-2009, 04:38 PM

I have three red ones,they dont make em anymore,so i gotz me some extras..

I would start by just clearing the codes.

Here ya go buddy......save you a step or two

Speedometer Erratic Movement, Fuel Gauge Does Not Go to Full After Filling, Engine Coolant Temperature Gauge Reads Hot and Coolant Temperature Light Illuminates (Reprogram IPC) #05-08-49-003 - (Jan 20, 2005)

2004 Pontiac GTO

Built Prior to VIN Breakpoint 4L296011

Condition
Some customers may comment on one or more of the following conditions:

• Speedometer jumps erratically. Gauge may go up to 200 MPH or not return to zero.

• Fuel gauge does not move off empty when tank is full.

• Engine coolant temperature gauge reads hot and coolant temperature light illuminates.

These conditions may be intermittent.

Correction
Technicians are to reprogram the IPC with an updated software calibration. This new service calibration was released with TIS satellite data update version 1.0 available January 10, 2005. As always, make sure your Tech 2® is updated with the latest software version.

Important: Vehicles built after the VIN breakpoint must have the IPC replaced to correct these conditions

Well just a thought, but I had a problem like this. My temp gauge was going crazy, so I brought it to the dealer. Turns out my water pump had a crack in it. Might not be the same as your problem, but I felt it would be good to mention just in case. After they replaced the water pump, its been fine.

theres no need to buy a new one it can be updated...opps should have said that,what I meant by clearing code..lol

LOL. I don't know what caused the LCD to leak though.

thats what i had thought at first...but then when it said it was overheating, i turned the car off then on right away and then it was back to normal...so yea i dont think it would have cooled down that fast if there iwas a leak or something..but yea good thing it wasnt anything big..WARRANTY EXPIRED!! and out of cash for anything right now..

Gonna bring this back up, since Im having another issue and cant seem to find an answer through the Search. Was sitting in the drive thru line at Taco Bell last night, and I noticed my temp gauge started to climb. Usually its a notch below halfway, but I watched it climb up to halfway. At this point, I turned on my heater to full blast, and heard the radiator fan come on. (Not sure which happened first, I think the fan came on THEN I put the heater on) The temp stayed at halfway up until I got back on the road, then went down to its normal position. Outside temps were low to mid 40's, about 98% humidity ('twas foggy) This same situation happened almost a month ago while sitting in my car waiting for it to warm up, but it went to the warning zone before I noticed and shut the car down.

My question is this.... How do I bleed air out of the system on an 06? Do I just use one of those Lisle funnels and do it normally, or is there some special procedure required for these? I've read that doing it the traditional way can cause huge air pockets to enter the system, which I dont want.

I trust you guys on LS1.com more than the dealers and mechanics around here by leaps and bounds. Thanks for reading.

Let the car cool and then let it run with the radiator cap off for a few mins to let any air bubbles escape. Let the car run til the needle climbs to normal operating temp and put the cap back on and drive it around for, I would say, 10-20 mins to see if the issues return.
