Project MPXS MAX!

Took the car back out for a short drive this morning and all seemed fine for the first 30 miles or so. I pulled into a gas station to gas it up and I noticed that the heat was back up to 190 as I pulled out of the gas station it started jumping up to 200 215 and on up the scale until I finally got it back in the garage it got up to 232. I don't even know how to begin to trouble shoot it when it is doing all the weird stuff its doing. The firm ride light came on and stayed on so that was the only thing I noticed that was off but im at a loss?
 
Have you cracked the bleeder nut to see if any air comes out? We use to loosen the radiator cap the first click and drive it and let the air that way.

Are the hoses hard as rocks? That usually means air.

Probably nothing stated here you dont already know/tried. :cool:

Will it heat up that much if air is in the system?

Was the cooling fan working when it started getting hot ? BTW, what kind of fan do you have on the car ?

Didn't have time to pop the hood and check it was heating up so fast, I had to get it home. The fans wouldn't work yesterday so I just assumed they had stopped working again. When I got home I purged the system and replaced the Ircm. I am going to bring it up temp see that the fans work, purge it and let it cool back down again.

You only purge cold. You will have a mess if things are hot.
 
Just started it up let it get up to 184 verified the fan kicks on like it should after replacing the ircm brought it down to 178 quick but the upper radiator hose was still hard as a rock. Guess I need to keep purging it like that for a while. Just wish it wasn't 95 deg outside for all of this.

What fan are you using ? Any trick wiring or override switches ? Have you done anything with the MAF wiring, related to the meth injection controller ?

Plug in a scan tool. It will cycle the fans. Quick and easy way to see if the fans/IRCM is functional.

The upper hose always gets rock hard at operating temperature. Perfectly normal and has nothing to do with air.

Took it for another 10 mile drive never got above 186 and the fans are stock and I know now that they are functional. Seems as though air in the system and a bad ircm was my problem but the only way I am going to know is by driving it lol.
