I just replaced my coolant expansion tank cause it had a huge crack in it, i put everything thogether and everything, but when i drove it home last night the temp guage starting going to the red but i dint hear see or smell anything wrong but it went to the red. I just left it somewhere cause i was too scared to drive it. Does the radiator need water or something?

fuse?had oil? don't think so how hot did it get check rad.make sure water in it ,if got really hot might be froze up chek battery also must have good battery
The lubricating and cooling systems are isolated from each other in your car. They should never mix under normal conditions. They mix typically when a crack in the engine block exists - or - if the head gasket is damaged. You will probably find the there is coolant in the oil pan, too. A white / frothy substance on the dip stick will be evidence of this.
A head gasket replacement can be a costly repair - but often significantly less than a cracked engine block. It can require a fair amount of work to determine which caused the problem. Depending on the age of the car, mileage, etc. - it may not be worth fixing / replacing. Consult a trusted mechanic to help you best determine your options.
Get a coolant if dye kit at autozone or similar. Put the dye in tank and run vehicle. When coolant tank is low use flashlight in kit to look for the crack
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.
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.
Whenever you overheat once, then the thermostat must also be replaced. It is operated by the expansion of a contained wax pellet, and overheating causes permanent loss of wax. However, you may also have caused a head gasket leak now from heat warpage. If the thermostat does not help, then borrow a cooling system pressure checker from a place like Autozone, and see of it holds pressure for 5 minutes after pumping it slightly above cap rating. Then start engine and see if it is steady or oscillating from 1 cylinder leakage.
you either have a blown head gasket or cracked head both reasons will put compression gas into coolant system since air gets hotter faster than coolant any air in system will cause very fast over heating and push coolant out. the ford 3.0 is has a record of this problem the fix is not cheap and if you do it your self or have a shop do it both heads should be done and the t stat also replacing water pump would be wise
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.
Sounds like blown head gasket (or worse) still to me.
Remove oil filler cap and look for grey oil.
Never use water these days but special coolant. Water makes vapour spots and cause block cracks, worse then blown gaskets!!!
vapour does not cool very well.
Look like you have cracks already.
Take a compression test if possible. But might not show op at that temperature.
The gauge indication troubles me.
broken fan belt water pump dont turn water dont circulate its gonna overheat alternator dont turn battery light stay on you said the bottle was full and when it cool down it was on low level that normal radiator took back what it was missing check the belt HOPE IT HELP FIXYA OUR POST THANKS PIERRE
