325e over heating

[BMW325E]

i have a 1987 325e im new w/it it over heated because my alternator belt broke , i relpaces car starts fine no smoke at all from tail pipe ,but if over flows like a fountian ,i read a few treads and i tried to bleed system i maybe doing some thing wrong ,bit still over heats ,im new w/bmws tbh but im pretty good w/tools and instructions thnx

Very likely air that needs to be bled out. Is the clutch fan working?

[BMW325E]

well i think so tbh i tried to stop it w/a sport page of a news paper and it ripped it apart so then t adde a few more papers same results , would you know how to bleed system properly i maybe done it wrong

[witeshark]

I don't know the exact steps for that car. I'd try a search for a DIY on that - there's bound to be one here somewhere.

Ty bro , its fustrating tbh, i wanna hit the road w/it

is the thermostat seized?

^ +1

air pockets in cooling system especially in the thermostat head will also cause the symptoms you are seeing. Try refilling your cooling system and re-bleed. I squeeze the radiator hoses while bleeding to purge all the air, and then 1 final squeeze and HOLD the hoses in squeezed position- close and tighten the bleed screw; then release hose.

Thnkz guys will try in the morning and gotKRAUTi took out thermostat ,im running car w/o it to see if it would do the job.

darkhorse737 i did all you have posted my temp gage only goes a little past half way mark, i test drive when i pull into drive way i open hood and fluid is over flowing threw the reservor cap, i check cap and its missing the rubber ring washer may this be why ? O and at idle on stand still fluid doesn't over flow at all . thnxz

i repace resrvor cap and still over heats im new to this , im reading on this problem i have and still cant get it to stop over heating any more technics any one have would be g8tly appreciated thnxz .i get steam coming from bleeder port when i rebleed after a few tymes also .

Ok i did a quick test , i discconnect the upper hose to rad at the rad end to see if fluid is flowing from engin into rad , yes it is , then i reconect ,and disconnect hose from thermistat housing to see if fluid flowing rad into engine ,very little fluid coming into engine from rad, my question is it normal or my rad is defective ? o and thrs no thermistat in car . thnxz

That's gotta be the problem! There's a blockage there.

on idle, the volume of flow will be small with an "open" cooling system.(say around 1/4 of the size of the hose), but it should increase if u up your revs.

on a "closed" system however, without the air pockets, the flow volume will be much more.

QUESTION: when you overheat, does your auxiliary fan come on?????? If YES, then maybe a clogged radiator. If NO, check fan switches and fan motor.

*bimmers temp guage will read at halfway mark or slightly higher, when engine is at operating temp(180-185 farenheit)

I hope, the overheat wasn't enough to damage the cylinder head gasket. If it did, then that could be the reason why...

TRY this: with no t-stat, fill up your reservoir to the top with cap OFF. then start engine. If it blows water, then that means u have cylinder compression getting into the cooling system...

Good Luck

Ok guys thnxz ill try all those request ,its raining atm ,but once done ill try and post ,once again thankz a mill .
