i started my car a few minutes ago then i drive it around to a frien house (driving slow) then this OVERHEATING EXH SYSTEM light came on i check my temperature guage fast and the temperature was cool what the hell is this ??????? what those OVERHEATING EXH SYSTEM means what can cause this to happen help fast ?????

 

It means your exhaust temperatures are way above average. That's a sign you're running very lean. I wouldn't freak out just yet, it could be a messed up sensor, but definitely treat your car gingerly. Can you think of any reasons why your car might be running lean?

that not possible because i run rich my air/fuel guges shows me that i am rich and i know that i am rich so that couldnt be it

 

well just in case it matter my ride is a 87 T2

 

clogged cat

 

how can you fix a clogged cat???? **** and what causes this?????????????

 

can i still drive with out a cause of doing anything to my car???????????????????????????????????????

 

The over heating exhaust warning is a indication (Although the first time I have heard of it lighting up) that your exhaust is over heatind (Duh)

I do not have my factory book but I believe that sensor goes off at +250°F. The sensor is located on the pass floor boards. Slightly aft of where the passengers feet would be. You cat may be clogged up.

Has power droped?

Is your cat glowing like the sun?

 

no power drop and my cats are not glowing ?????????????

 

You don't want to drive with a clogged cat. I had a friends blow out when we were on the highway and a car behind use hit it and had a wreck. Thats what can happen if its real bad. You should buy a new one or gut it.<<<<Gutting not recomended from me.

but in just in case in clogged how do you fix it????

 

when it is clogged does the exaust sounds different ?

 

mine didn't. I didn't have a power drain either. Seemed to have good exhaust flow. But when we checked it out it was all messed up. I don't see how the air got through it.

Ok, you need to do this. That sensor comes on when that floorboard gets very hot.

Drive it...get that light on...and feel the floor board. Is it hot.

Also, how many minutes does it take for it to come on. Maybe you can lie under the car with a hand hoving under the cat to feel how hot it is getting. If it is still cool and light comes on your heat hazard thing is having issues

if the cat is clogged, you'll need to replace it... you can't "fix it"

Just by the over heat and the mention that you are running rich would suggest this to me.

If you are running too rich, that will cause the cats to over heat as well, eventually melting the cores into a nice pile of slag.

Fix the A/F mix first, then hope you haven't caused major damage.

 

******* worse day of my life, well i drive my car around to a friend house(little far) a couple of minute my car shows the warning light of oveheating exh system well i keep on driving then it goes away then a couple of minute it come back on, i was checking my temperature of the car all the time it seems fine well got to the place i was going ,later it was time to go home and then like 5 block from where i was parked i see my car temperature going high i was like **** what the ****, i park my **** then i check under my hood there was water fumes every where ,i look i knew that there was a coolant problem i look and look and finaly found it it was a danm hole in my radiador hose ,well how the hell was i going to fix this in the middle of the night it was around 12:30pm well thanz to my smart *** i cutted the radiador hose and put it back together (the hole was close to the clambs thanz to that) well i also keep some coolant in my car just in case u never know what can happen well finally i finish doing al that **** and i got home just fine temperature was good and another thing my OVERHEATING EXH SYSTEM light never came on in the way home so i guess that got fix (what a night)
