I got the bolt now i will cross my figures that they fit and bmw isnt a complete asshole when it comes to pulling hex and torx bolts in the most retarded places.

i also stuck my hand back there to see if one side felt warm or not. i did not feel any heat on the hoses. but i know my thermostat isnt stuck closed because i can squeeze the large radiator hose on passenger front and it builds up pressure and you can also feel flow. also having the radiator cap off you can see some flow. unfortunetly no heat yet. we'll see tomorrow after i go for a drive. if i get my heat back the car will be back to...

Just watch that temp needle like a hawk. If you see it start to rise above the 12 o'clock position, shut her down immediately. You may have a different issue than the OP. Sounds like your thermostat might be stuck in the closed position.

The head gasket is actually pretty easy. Lock the cams, static timing, new gasket kit, head check....pretty straight forward. Bentley details it just enough for your average diy. A mechanic will only need it for torque specs.

Drill hole in the bolt, use an easy out or bolt extractor.(they are a oversized drill bit with a reverse thread, reversing the drill drives the extractor into the bad bolt and reversing the bolt out.) They are sold, at hardware stores, auto parts stores, maybe walmart. You may need to take the cooling fan off to have room for a drill. When you drill the pilot hole make sure it is smaller then the extractor your using. Make sure the pilot hole...

If you drop that part number into google you will see some sellers. But, is it very different from a hardware store bolt?

getbmwparts and pelican list it, try one of them.

I just changed the rear Y fitting on the engine, yes, you have the hoses hooked up right. Mine after parking in steep driveway, getting all air out, heater worked fine again (this morning) then I drove about 5 miles, overheated again, so now I'm looking at a head gasket. Pressure is building up and blowing out the coolant everywhere. So I would suggest trying to bleed the system again. At least your head gasket isn't blown. I have...

i'm having the exact same issue after replacing both of the plastic cooling bits and the t-stat. I've bled it a few times already. the air blowing in the car during the bleed is the same temp as outside. Out of curiosity I reached thru the mess to feel the heater hoses going into the heater core. both cold. trying to see if I was getting any circulation at all after the car was warmed up I felt the rad hoses, top was hot, bottom cold...
