with the engine cold, check the coolant level, you are probably down a little since you changed the hose. just be careful if you run it low on coolant you can crack the head and the temp sensor will never indicate a problem.

Did you bleed the system after changing hose? That's easily overlooked

yeah, you might have some air trapped in the system that would cause it to throw a light from time to time...

plus if it hasn't been done in a couple years I would consider a flush just to keep it running nice. I don't know about the e46 but the e36 you need to change the radiator after about 5-6 years because the plastic becomes brittle and it breaks down with disastrous results.

Guys thank you so much
I ll keep that in mind specially I ll be doing service for oil change pretty soon so I ll go ahead flush the whole things and replace with new fluid...
btw anyone of you familiar with what type of fluid for power steering cz I have read it in the cap and said ATF fluid only so want to make sure that the transmission fluid with dexron work for that
Again thank s for u re time and help

Coolant should be flushed every other year and your PS fluid is Dexron atf (you can use about any of the dexrons available - latest is dexronIII but you can use the earlier versions - they're a little cheaper but make sure it says DEXRON)

Thank you for the confirmation buddy...i m glad I did used dexron to top off last time...This is a new project for me to learn and maintain cz is my wife who drive it...anyway thank s again and I ll definetly will flush those radiator fluid by the time i change the oil as well..

also when adding PS fluid - after topping it off slowly turn steering wheel from left stop to right stop and back to left stop - barely touching the stops and just for a couple of secs each - this bleeds air from the system.
