| | | Have An Idiot Light Lit | Joined: Feb 2012 Posts: 271 enthusiast | OP enthusiast Joined: Feb 2012 Posts: 271 | I have no idea if it's been lit since the good folks at Ford put the friggin' lights at knee height on the left side but my exhaust light is lit. I imagine this is contributing to the overheating perhaps? I'm clueless where to start with this and am in some podunk town at a RV park currently so not much I can do about it tonight but a general idea of where to start would be helpful | | | Re: Have An Idiot Light Lit | Joined: Dec 2000 Posts: 4,043 pooh-bah | pooh-bah Joined: Dec 2000 Posts: 4,043 | EGR light?
Those are setup to turn on after XX,XXX miles. It's to get you into the dealer for service.
Mine went on in my Dodge at the 75,000 mile mark. Funny thing was, I no longer had an EGR since I swapped intakes and carbs a year earlier.

Would needing that replaced also cause me to overheat? Is this an easy fix that I can do here in an RV park? | | | Re: Have An Idiot Light Lit | Joined: Aug 2008 Posts: 18,213 Likes: 2 Supreme Master | Supreme Master Joined: Aug 2008 Posts: 18,213 Likes: 2 | If it's a yellow ck eng light then that has nothing to do with making it run hot.It's probably a sensor or just needs to be reset.

I'd just plug the vacuum line and leave it alone.
And no, I am not aware of any way a defective EGR valve would cause overheating, it's just emissions junk. (Exhaust Gas Recirculation, it takes a portion of the exhaust gases and re introduces them into the intake. Makes your truck run lousy and get crappy mileage)

This will tell you why the computer turned the check engine light on. Instructions on how to run a self-test and pull codes are found HERE The terminals you want to use are found on the passenger side of the engine compartment around the battery. Explanations of the codes are found HERE

I can do mine with a paper clip. you can also pick up a code reader at any local parts place, but I am guessing someone in your travels will have one. and I would go with what wookie said, disconnect the vacuum line from the EGR valve and plug it. and it won't have anything to do with temp, your overheating needs to be looked into and solved before it gets much warmer out or you could get stuck or do damage 90 Astro - "The Grey Ghost" - Haulin Ass, Not kids.E-Z Vanners and West Vanners Council of Councils Board Member National Truck-in Board Support Team "No matter where you go, there you are."

The fuel injection system is designed to have a functioning EGR valve and it will not hurt performance if left in place.
Pull the codes and see what they are before you buy any parts or make any diagnosis. Overheating could be many things, including a failed sending unit. First thing I would do is pull the thermostat and make sure it opens right. Get a cooking thermometer and put the thermostat in a kettle of water and see at what temp it opens.
