Cooling Problems!?!?!?

[Rekless56]

How you doing..i replaced the radiator, fan shroud, fan, and coolant tank on my 93 325i...but for some reason i still have a coolant leak...i have checked all the hoses..they are tight..so im stumped...Any ideas????

[witeshark]

Do you have a way to get it pressure tested?

[Rekless56]

No...Could that be the problem???

[witeshark]

It could be a way to find the leak.

[Rekless56]

How would i go about doing that??

[witeshark]

You may need a garage to do it; they are equipped and know where to hunt the most likely leaks.

Put a fluorescent dye in the coolant system then you should be able to see the leak.

Bad water pump?

[marti5]

Viscous coupling or you have air in the system, if you roll up a news paper and stick it in the fan and it stops its the viscous coupling as for bleed ing the system correctly always do this from cold, fill up with engine off and A/C on max heat but fan at lowest setting. fill and bleed you may have to do this several times, if this fails as Whitshark says possible waterpump.

I am thinking bad water pump too...the coolant tank was full so i thought thermostat but yeah...

how do i bleed the air out of the cooling system when i change the water pump??
