DIY's?

[bigbill89]

i dont think its the fan clutch cause i hear it engage and it looks fairly new i just bought the car about a week ago do u think it could be water pump

shogun do u think it could be a bad water pump

[jessejames]

where is the coolant leaking from? there's a seep hole at the bottom of the water pump
if the coolant is leaking out of that seep hole, then yes, it probably is going bad
if it's coming from up higher, it could be your thermostat gasket or an o-ring
you should have changed the thermostat gasket when you changed the thermostat, did you?

[bigbill89]

yep i changed the thermostat and and the gasket

[StealthBimmer]

Yes, it could be water pump. It could be a number of things.

did you bleed, bleed, bleed?

This is the most common issue after any cooling system work.

1. turn on heat all way, fan on high
2. start car and let it get to temp (thermo opens)
3. shut car off, bleed, add coolant
4. repeat until no more air comes out.

ive had the car for a little over two weeks the first week it ran fine then i woke up about three days ago and drove it about three to four miles and it was over heating it never got in the red when it over heated but that was cause i never let it so i started with the t stat and its doing the same thing

Bleed it some more.

[russiankid]

M50's can be a pain in the ass to bleed.

[ShapeShifter]

It might help to Jack the front of the car when bleeding to cooling system.
This helps to bring the air pockets to the highest point in the system.

[Chinman]

it would over heat that fast cause air inthe sysetem

If there is a lot of it, yes.

[bigbill89]

why would it just start over heating with no sign of anything going out thats y i started with the t stat what would u replace next the water pump or the fan clutch

[Chinman]

Water pump. The factory ones have a plastic impeller that breaks off eventually. If you replace the water pump, buy one with a metal impeller. You can get them from bmaparts.com

[russiankid]

The impellers break off do to the lack of maintenance on the cooling system. Changing the coolant every 2 years along with the inspection of hoses is a good way to care for the system. Always use quality coolant and NEVER use tap water, always use distilled water mixed with coolant.
