Yes I know I could have done the CCV PVC delete but I want to keep is as much stock as possible. Yes Im doing a full oil change as soon as Im sure there are no more water leaks. Once it finally blew out you could hear the air had a clear pathway from the crank vent line. My crank case vent line that Y's off the dip stick was also a solid block and took a bit of digging, de greaser (B-12) and air to get it clear. Most of my emissions hoses were pretty gunked up and a few solid. The 1/2 crank vent hose the connects to the bottom of the water/oil separator is about 4in short and the hose that connects to the valve cover is about 1/2 to long and wont flex like the OEM so I had to use the old one. One of the hard lines has a bend in it just enough to make it impossible to bolt the electrical box onto the manifold. I ordered the Crankcase Vent Valve Breather Hoses and oil separator kit from Amazon as well as the heater hard lines. I had to order a new hose.Īnother lesson learned, spend the extra $$ to get OEM parts. Perform on a cold car, you will loose only a slight bit of coolant due to cooling system vacuum. It seems the retaining clip for the O-ring must have gotten stuck to the old thermostat housing and already went out with the trash earthier this week. O-ring is no listed in the parts catalog, it is BMW Part 13621743299, about 2 and it does not require any tools to do the job, just your fingers to unlatch the connector and release the fan switch with the 2 plastic tabs. I would be done if it were not for my lower radiator hose having a huge leak where it connects to the thermostat. Each time it started to down pour 2 minutes after I closed the hood. Thank you to God for holding off the rain yesterday and today both times until I was done working on the BMW even though we had high wind and rain warnings. 2001 BMW 330ci coolant light came on a few days ago fluid had appeared to leak 95 plus degree temperature added coolant twice over past 3 days, probably a tad too much today. Replace the bleeder screw (not tight.just enough)Ģ) pour coolant into the expansion tank until the bobber is at the max level (engine is cold of course)ģ) turn the ignition to position (2) and set your climate control to low fan and max temp (this will start the aux pump)Ĥ) after a few minutes, I heard gurgling in the expansion and the bobber droppedĥ) pour more coolant into expansion tank until the bobber is at max level againĦ) replace and tighten the expansion tank capħ) start the car and take her for a spin to get to operating temp I did the following steps when I refilled coolant into the tank:ġ) pour coolant through the bleeder screw hole until it tops off. Thought "did i have too much coolant?" So try this.īe sure you're bleeding the system correctly. It could indicate various issues, including a low coolant level, malfunctioning cooling system components, or engine overheating. If the coolant and oil look clean and no airlock, the next steps I'd look at would be a potentially duff sensor, then possibly an early fail sign on the thermostat (eg it's opening and closing but at the wrong temps)Īlso get a compression test done to rule out the head just read your complete posting and apparently what i responded with isn't helpful.Ĭan you see coolant at the top of your expansion tank? When i refilled mine.the bobber was at max level and I didn't see coolant at the top. What Does the BMW Coolant Light Mean The coolant light on the BMW dashboard illuminates when there’s a potential problem with the engine cooling system. What's the temp gauge doing? (although iirc that's oil temp)Īlso check for an air lock in the coolant, maybe bleed it? No sign of oil contamination in the coolant?īoth the above possible head gasket fail but don't panic, mayo can also come from short journeys Couple of things to check to try and rule out the obvious expensive things: If you're not losing coolant, it's a good sign. I'd expect that to cause flickering on and off though. Although I don't know the zed specifically, a lot of these work by grounding the line when they overheat, so if the wire comes off and is flapping around it will short and the light will come on. Is the car misbehaving in any way? Running rough etc?īefore anything else, see if the wire has come off the sensor.
