steam from engine temp gauge at 12 o'clock

[rossfarmer]

Hey all,

I have searched the forums and can't seem to find this answer. With all the smart people here I am hoping to find my answer. When I drive the car 10 miles or more I see steam comming from the passengers side grill when I stop. The temp gauge stays straight up. I can also smell coolant. Thanks in advance for you answers.

Thanks,

Does your radiator have plastic on the side tanks? If so, there may be a split and this is certain to fully rupture; I'd replace the radiator right away.

Welcome to the Werkz

Like WS said the stock radiators are renowned for the plastic side tanks seperating from the metal assembly. I have just finished replacing mine with one of these units Zionsville Autosport: BMW E39 - E38 Super Duty Cooling Kit. Not exactly a cheap option, but given that the cost and inconvenience of an "on the road" failure i felt it was worthwhile, but only if you plan to keep the car for any length of time.

Have a look when the engine is cold and you should be able to see the tell tale white residue from the coolant down the seam where the plastic and metal parts join.
