Replace coolant expansion tank line 1998 xj8

I have PNMNC 4583AC Expansion tank hose. It has connectors that I am unfamiliar with. I want to replace the old one, as it has disengaged the inner tube from the connector at the radiator. I want to avoid damage. How do they work?

SOURCE: leaking coolant checked radiator hoses and

take a look at the waterpump, these cars have problems with waterpump leaking, take caution, the waterpump is driven by the timing belt,if that belt pops or jumps due to coolant leaking on it and causing it to fail,then you will have a costly repair,i belive its about $4,000 to fix, it will cause cylinder head valves to bent, have this coolant leak check asap.

Coolant is not flowing into expansion tank via little hose and car is overheating. As it is getting hot the coolant bubbles and spits coolant through the little hose but it is sputtery like it is tryi


coolant will not flow from the return pipe continuously.when the engine heats the coolant expands returns to tank. coolant fan starts engine cools down return pipe flow stops . fan stops after times, again coolant heats up and flows through the pipe. this cycle continues and go on.

THERMOSTAT COULD BE STICKING SLIGHTLY CLOSED.CHECK COOLANT LEVEL MAKE SURE COOLANT NOT LOW.IF COOLING NOT BOILING OUT OF THE EXPANSION TANK. I WOULD HAVE CAR HOOKED UP TO A DIAGNOTIC SCANNER AND CHECK COOLANT TEMPERATURE SEE IF TEMP. OVER 230 DEGREES IF SO RADIATOR COOLING FANS NOT WORKING.COOLANT THERMO SWITCH BAD BOTH FANS SHOULD BE RUNNING AT LOW SPEED.IF ALL LOOKS GOOD YOU COULD HAVE FAULTY LOW COOLANT SENSOR IN EXPANSION TANK.MAKE SURE COOLANT IS IN THE EXPANSION TANK BECAUSE COOLANT LEVEL COULD BE LOW.ADD COOLANT IN THE EXPANSION TANK UNTIL YOU AT MAX LEVEL LINE ON THE EXPANSION TANK.DONT OVER FILL THE EXPANSION KEEP ADDING COOLANT UNTIL COOLANT LEVEL STAYS AT THE MAX LEVEL LINE ON THE EXPANSION TANK.

I WANT TO KNOW HOW TO REMOVE THE COOLANT RESERVOIR ON A 2000 BMW 323CI


Are you talking the expansion tank? If so - Drain coolant first by going underneath the car and take off the protective shield and unscrewing the blue plastic screw (make sure the car is NOT hot!), under the reservoir you'll see an electronic sensor - carefully twist is a 1/4 turn counterclockwise and gently pull downward to remove this sensor don't force it, you don't want to pay $150 to replace it. Disconnect the hoses on the top and bottom of expansion tank by pulling up the metal tabs upwards then pulling the hose away from the tank. I believe there are two or three screws which hold the expansion tank bracket in place, unscrew these and pull the bottom of the tank away from the radiator then lift upwards on the bracket (the bracket and expansion tank should then come out). Get the old expansion tank off the bracket and replace. You want to take off the bracket because getting a new tank on the bracket is a B*TCH!

Reconnect in reverse order.

Make sure to bleed the cooling system properly to remove air pockets (please use BMW coolant and distilled H20 in 50/50 mix - it's not the same as your Prestone or other mass produced coolants). Last replace the expansion tank cap because that might have created the expansion tank cracking.

Good luck and hope this helps

How do I change the coolant


Hi!!
On the bottom of the radiator, there is a drain valve, just open it and drain fluid into a container, if you want faster drain, remove bottom radiator hose.
NOTE: DO NOT OPEN SYSTEM WHEN HOT, COOLANT IS POISONOUS FOR PETS, KEEP IT AWAY FROM THEM.
Good Luck!! Rate this post!!

I have a 2004 BMW 330i and have replaced everything in the coolant system, and my vehicle is still leaking coolant out the expansion tank, or the cap where you add coolant to the radiator. I have use OEM...


We have had some similar problems with some BMW's,the last one we replaced the expansion tank.Before we attached the upper radiator hose to the radiator we filled the engine with antifreeze through the hose.Install the hose and fill your expansion tank to the proper level and run the engine to operating temperature.

Start loosing coolant when temp comes to 220.


Should run between 195 and 215. Get it pressure checked to find leak. Head gaskets give problems on this motor.
