raditor cap

[bmwrp8]

guys, i found why im loosing coolant, my rad. cap was bad and a friend gave me a new rad. cap. and problem was gone., but my original cap has has 140 labeled in the top and my friend gave me 200, he said its psi... never knew that our rad caps has psi's labeled on them i thought they where just caps. My question is is it ok for me to use the 200psi cap that my friend gave me or should i buy the 140 ones? tnx in advance:)

supposed to have the 1.4 bar or 20 psi cap. Buy the 140 for it before you blow the heater core seals.

... Bill if it's no trouble could you read my heater core leak thread (http://www.bimmernut.com/forum/showthread.php?t=40298)?

i guess i should put the 140 back in there... d'oh...

[Bill R.]

will be familiar with it and should know the details, the early 525 used the 1.4 bar cap and most of the other 5 series used the 2.0 bar cap. The recall replacement caps were designed to vent coolant more rapidly if excess pressure built up in the cooling system. The fear was that excess pressure would occure in an overheating car and the heater core or heater core seals would blow and scalding coolant would hit the driver or passengers feet. The recall replaced all these caps with the new design. If your cap has never been replaced i think the dealer will still give you the new design cap for your car.

NHTSA CAMPAIGN ID Number: 98V178000
Summary:
VEHICLE DESCRIPTION: PASSENGER VEHICLES. A MALFUNCTION OR FAILURE OF A COOLANT SYSTEM COMPONENT, SUCH AS A THERMOSTAT, WATER PUMP, OR FAN BELT, CAN RESULT IN SIGNIFICANTLY INCREASED COOLANT TEMPERATURE AND SYSTEM PRESSURE. IF THE INDICATIONS OF A CRITICAL OVERHEATING CONDITION IS NOT NOTICED BY THE DRIVER, IT IS POSSIBLE THAT DAMAGE TO, OR FAILURE OF, A COOLANT SYSTEM COMPONENT COULD OCCUR.
Consequence:
IF A CRACK WERE TO FORM OR A SEAM WERE TO SEPARATE IN THE HEATER CORE END PIECE, HOT COOLANT COULD SUDDENLY BE EXPELLED, INCREASING THE RISK OF PERSONAL INJURY TO A VEHICLE OCCUPANT.
Remedy:
DEALERS WILL INSTALL A NEW DESIGN RADIATOR CAP TO CONTROL PRESSURE AND PROVIDE GREATER COOLANT OVERFLOW IN THE EVENT OF OVERHEATING.

man i feel like a dork -

last winter i overheated (water pump failed) and the cap popped off. i decided to replace the radiator cap just to be safe. so i went to a local parts store and they gave me the 200 cap. i found the recall notice and assumed the 200 cap was the replacement.... d'oh d'oh d'oh i should have asked you guys. i'm guessing i had the right cap already and it functioned as it should when i overheated. i thought the cap would be rated to pop at a certain temperature, not to regulate the whole system.

hopefully i can ride winter out and just need to replace the o-rings around the core in the spring.

put the 140 cap back.... no coolant on the windscreen today but it's too early to tell - thanks for the thread bmwrp8 and replies guys... massively helpful!

200 should be replaced with 140 on all 5 series? Never heard about this Bill, just copied this to the maintenance section. Need to add this to my wish list.

200, there are redesigned versions of both caps. The m20 motor uses the 1.40 cap and all the others use the 2.00 cap. But if you have an old cap you might be entitled to a new redesigned cap from bmw, since a lot of people didn't bring their car in for the recall years ago. Your 850 is also on the list.

My 1995 m50 has the 200 cap. I think it was replaced with my radiator last fall. Should I be using a 140 cap?

[Bill R.]

m20 motor has the 1.40 cap , yours has the 2.0 bar cap.
