Have a cadie 01 changed water pump and thurmostat and still over heating and running hot any ideas

CHECK IF THE PUMP COUPLING IS THERE IF SO TRY BLEEDING THE RADIATORS UP STAIRS TO SEE IF U GET COLD OR HOT WATER N IF THE WATER IS DIRTY. THEY LINES MIGHT HAVE AIR IN THEM. IF U TRIED THESE N STILL NOT GETTING HOT U WILL NEED TO CHANGE THE MOTOR N COUPLING

Radiator fan not working. Water sensor. Bad radiator. Fan fuse. No power to d fan. Etc.

the problem could be either the thermostat or the water pump may be faulty......cheers.

REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.MAKE SURE COOLANT NOT LOW.IF ALL IS GOOD CHECK FOR LEAKING WATER PUMP WEEP HOLE IF LEAKING REPLACE WATER PUMP.MAKE SURE COOLING FANS RUNNING.IF ENGINE RUNNING HOT WHILE SITTING LONG TRAFFIC LINE AND COOLANT NOT RUNNING.CHECK COOLANT FAN RELAYS AND FUSE.IF ALL IS GOOD HOT WIRE MAKE SURE COOLING FAN MOTOR GOOD IF COOLING FAN DONT RUN WHEN HOT WIRED FAN MOTOR BAD.IF FAN MOTOR OKAY AND FUSE RELAYS GOOD YOU HAVE FAULTY COOLING FAN WIRING.YOU COULD HAVE BAD ENGINE COOLANT SENSOR OR FAULT IN ECM CODE SCAN TO CHECK THEM BOTH.CHECK ENGINE OIL.LOOK LIKE MILK SHAKE YOU HAVE LEAKING HEAD GASKET.IF OIL LOOKS OKAY.YOUR ENGINE BLOCK, RADIATOR AND HEATER CORE NEED FLUSHING.

check thurmostat water pump worst thing head gasket

remove expansion tank cap (if fitted) take off the highest hose clip in the system and fill from there if you have an air lock in the system it will be obvious...after connecting back up, fill tank with neat anti freeze.(if tank is higher than hose, fill tank as air is expelled from the pipe.)

There is a valve on the line to the rear heater core. Sounds like when actuated, the water is not coming to the rear core. What you must do is locate the lines to the rear core and see if they are both hot, (incoming and outgoing)..this will let you know if what I am saying is correct. Secondly, if they are not, you must locate the valve on the incoming hot line and see if it is working when you attempt to heat the rear...If not, you either have a bad valve or the linkage is not opening and closing the valve...A visual inspection by one person while the other is turning it from heat to cool should confirm which it is. Good Luck! I hope you find this to be very helpful!

mite still be air in system! try bleed screw on top off rad! if that does not work i say ur water pump is fucked

Reverse flush the cooling system and put in fresh antifreeze to -20. (20 below zero). If that doesn't help, replace the thermostat.

the thermostat is stuck open. Youv'e got a little rust in the coolant, right?
