Need Help With Jeep!

[TapouT]

Every time I've drove my Jeep since gutting the cat out it has been hissing from the coolant tank each time I shut it off after driving. Well today I drove it for maybe 10 minutes and it was hissing while driving it and kept trying to cut off and I got it home and popped the hood and it was hissing loudly and smoking from the coolant tank. It didn't leak much coolant though. Was my Jeep overheating? I'm sure it was but I've drove this thing in 90+ degree weather and it did fine and it was rather cool outside today Also, it's never done the coolant hissing thing until after I had gutted the cat. What could be the problem and what's the solution to fix it? Please help! Thanks! This is for a 1989 Jeep Cherokee with the Renix Model 4.0 I6.

No, it's sort of light brown but it's been that way since I got the Jeep back in may.

Whats on the Temp Gauge when its doing this? What Temp?

clogged up radiator probably. If the coolant is brown it needs to be flushed real good, flush the vanes in the block too.

Sorry I meant to mention this...It's a Pioneer model so it doesn't have a Temperature gauge that shows what the actual temp is all it is a warning light but it did not come on.

you need to invest in a temp gauge its worth it id check the seal on the thermostat housing or for any cracks on it
