What coolant should i use for 04 3 series? - 2004 BMW 3 Series

when you shut a car off the coolant temperature and pressure actually increase since the coolant is no longer circulating. I would say you probably has a small leak that the coolant is only able to breach after it reaches a certain pressure.

Get coolant temp sensor checked.

Get the coolant pressure tested, its definitely leaking coolant. You will need to get the coolant running line.

Pressure test will help you to know from where exactly coolant/refrigerant is getting leaked.

probably the water pump. front and center of the engine, the pulley that may or may not have the cooling fan attached. from under the truck a leaking water pump usually leaves some coolant residue on the timing cover and at the front of the oil pan where the wiring harness come across.

check you radiator fluid it is low

On a 3.9 V8 it is on the end of the hose under the
power brake booster,next to the degas bottle (coolant container)
below master cyl

On the 3.0 V6 it is on top off a coolant hose near
the throttle body

If this happens when you are idle, and then you get hot air as you drive, most likely you have low coolant and it only cycles as you drive. Get approved dextrom gmc coolat and cap off your coolant it is most likely low.

BMW Coolant is blue.

You're going to lose some coolant, so have a bucket or other container, and some fresh coolant, ready. Follow the upper radiator hose to the point where it's connected to the engine. The hose is clamped to a metal housing (water inlet) which is bolted to the engine. Remove the bolts (not the hose) and lift the housing to expose the thermostat (may require a little prying with a screwdriver or similar tool). Note how the old thermostat is fitted (which end is up), lift it out of the engine, and then remove all traces of gasket from the housing and the engine. Install the new thermostat and gasket, replace the bolts, add coolant as necessary, and you're done.

easiest way is to open drain plug on the radiator let it drain in bucket till it stops refill with water until you get all the coolant out. next time you refill put a cleaner in it and run it down the road at normal operating temperature for about 30 minutes let it cool off and flush it a couple more times with just water when it is clear add antifreeze in a 50/50 mixture one bottle antifreeze one bottle of water.
