hey guys,
im having a issue with my cooling system. my coolant is coming out the reservoir at exactly 97 degrees Celsius. tried everything to purge but i'm noticing i still have a lot of air in the system. this caused a bigger problem because me not knowing was confused as to why my coolant fan would not work at low speed. not knowing low speed kicks in at 105 degrees. sadly i changed everything i cud down to the ecu/dme . now we realize im overheating at 97 degrees. anyone had this problem? or have any ideas? car has new head gasket new water pump thermostat coolant sensor. i believe it has a new oil cooler heat exchange as well. out of ideas!!!!!
oh ye its a 2002 R53

 

Going to move this to the Gen1 Stock Problems/Issues folder.

Check out the below thread. Wondering if you have a blockage in your lines. Relative to bleeding, check out the second thread where I added something on how I drain and refill my coolant system. And remember there are two bleed screws (the second thread has info on the second screw).

Thats good advice will check all the lines before I go any further . What has me stumped is 97 degrees each time the coolant explodes out the bottle. Why just that temp?

 

I had to go back and real celcius. 97*C and F are terribly different. So, not quite boiling.

Somehow there's no flow. I'd start by pulling the thermostat and double checking operation - drop it in a pot of water and watch until it opens. Also, not sure if it's possible in an r53, but make sure the thermostat is installed properly in the housing. I installed a thermostat backwards in my e34 in college and it took me forever to figure out why it was overheating.

 

I did some construction consultant work on an ERL (an x-ray type laser). Was dealing with 4 degrees Kelvin. A 1/2" coolant pipe was about 12" in diameter when you added all the layers and insulation.

4 degrees kelvin = minus 269 celsius or about minus 452 fahrenhiet

On a t-stat, the spring portion goes into the engine and the crown goes toward the radiator.

 

I haven't heard kelvin since I dropped out of engineering freshman year... Sounds like a fun project!

 

I asked one of the physicist what type of tolerance they would need on the concrete floor. He says 5 angstroms that I write down like a dummy. I come to the next meeting a week later and have to tell him we cannot get that type of tolerance (an angstrom is like the size of an atom) on a concrete floor, lets plan on 1/8" in 10'. He looks at me, and in a disappointed look says "OK I will just have to shim the track." I had to sit there with a straight face as in my feeble mind all I could think of was a screw jack for an atom.

 

What was the verdict on this?

 

Havent had the chance to get into it this weekend will try all suggestions. Check the coolant lines oil cooler heat exchange. What I did do was check the radiator. Pressure test and that's fine .
