hello, i got a 2001 disco, i just replaced the radiator 2 weeks ago because i broke the other one mudding, it start overheating so i i check the fan clutch and it was bad so i decided to replace it with an electric one, it works fine, it does not overheat while driving in the city, but ones i drive it in the highway and stop it does overheat, also im getting a code that says catalytic damaging, any ideas??? please help is driving me crazy!!

 

How many miles on it, did you replace the t/stat, does it have the bleed screw located on a black plastic tee or molded into the upper hose, do you know how to bleed the system?

 

it has 96000 miles, the weird thing is that i can drive it in the city with out trouble but went i jump in the high way and i exit it is went it overheats, the electric fan is working fine with a thermostat, i have not change the radiator thermostat, but it seems to be working, and the codes that im getting are catalytic damaging, oxygen sensor bank 1 and catalytic damaging misfire piston 8,4,2. im going to take the catalytics off monday and see what happens!

 

Next time only post one thread regarding the same issue.
As for your issues, quit driving it before you blow a head gasket and send me your number so I can walk you thru what to check.

 

sorry, im new to this so i post it in the wrong place the first time! tomorrow im checking what codes im getting, i took out the intake because i found out that i had a leak in the intake, is running a lot better and the check engine is not flashing anymore, also i found that i had a coolant leak by the throttle body, the only problem is that one of the bolt broke trying to take it off, so i bypass it until tomorrow that i can get it fix, it is ok to drive it like that till tomorrow?
