e34 coolant warning
Just managed to sort a thermostat replacement problem (long story but
basic symptoms were heater blowing cold, temp needle cold etc). Everything seems fine now with new t'stat and circulation. however, now the only niggle i have is that the coolant level warning light on the dash flashes and bongs. The header tank is full with coolant, the heater works perfect, the temp needle is nicely sitting in the middle of the guage and the bleed screw on top of the t'stat housing lets out only coolant when opened... so i'm wondering what's with the warning? do i have to reset it somehow or is there something else i'm missing. tia mojo |

It sucks to be you.
You have to pull the sensor from the bottom of the radiator tank and clean it, or maybe replace it. You could try unplugging it and cleaning the connector pins just in case there is a poor connection that makes the car think the radiator is empty. The reason it sucks to be you is that you have to drain the radiator again ....

Thanks for this but for crying out loud!!!!!!!!!!
do you mean there's a sense at the bottom of the actual radiator or somewhere near/in/on/at/under the header/filler tank by the bulk head? in other words, where exactly do i find this sensor doodah? scuse the ignorance... but how come i have to drain the rad again? thanks Mr Strickland... mojo "Jeff Strickland" > wrote in message ... > It sucks to be you. > > You have to pull the sensor from the bottom of the radiator tank and clean > it, or maybe replace it. > > You could try unplugging it and cleaning the connector pins just in case > there is a poor connection that makes the car think the radiator is empty. > > The reason it sucks to be you is that you have to drain the radiator again > ... > > > > > "mojo" > wrote in message > om... > > Just managed to sort a thermostat replacement problem (long story but > > basic symptoms were heater blowing cold, temp needle cold etc). > > Everything seems fine now with new t'stat and circulation. however, > > now the only niggle i have is that the coolant level warning light on > > the dash flashes and bongs.

You don't. I don't know what the previous poster was thinking, but the
coolant level sensor is in the reservoir tank, not the rad. -- "mojohotmail" > wrote in message . uk... | Thanks for this but for crying out loud!!!!!!!!!! | | | do you mean there's a sense at the bottom of the actual radiator or | somewhere near/in/on/at/under the header/filler tank by the bulk head? in | other words, where exactly do i find this sensor doodah? | | scuse the ignorance... but how come i have to drain the rad again? | | thanks Mr Strickland... | | mojo | | | "Jeff Strickland" > wrote in message | ... | > It sucks to be you. | > | > You have to pull the sensor from the bottom of the radiator tank and clean | > it, or maybe replace it. | > | > You could try unplugging it and cleaning the connector pins just in case | > there is a poor connection that makes the car think the radiator is empty. | > | > The reason it sucks to be you is that you have to drain the radiator again | > ... | > | > | > | > | > "mojo" > wrote in message | > om... | > > Just managed to sort a thermostat replacement problem (long story but | > > basic symptoms were heater blowing cold, temp needle cold etc). | > > Everything seems fine now with new t'stat and circulation. however, | > > now the only niggle i have is that the coolant level warning light on | > > the dash flashes and bongs.

Just checked the header/res tank and the sensor's in there. a black plastic
hex nut holds it in. terminals and white plastic float thingy look okay but will replace and see what happens. thanks again mojo "spare-me-spam" > wrote in message ... > You don't.

"spare-me-spam" > wrote in message ... > You don't. I don't know what the previous poster was thinking, but the > coolant level sensor is in the reservoir tank, not the rad. > -- Right. It's on the bottom of the expansion tank. If you don't drain the coolant before you remove it, everything in the tank and in the system above the hoses leading into it will drain all over your garage floor. I'm sure Jeff just mis-spoke when he said radiator. Kyle. |

Hi
thanks for this but... it's not. on my model, it's in the top of the expansion tank, right next to the filler cap thing. btw, the exp. tank itself is situated at the bulkhead/beaneath the windscreen. i guess there are maybe the same models out with some different design ideas or mods. thanks mojo "Kyle and Lori Greene" > wrote in message . .. > > "spare-me-spam" > wrote in message > ... > > You don't.

Yes, because they have different engines in them. There are several different engines used on E34's and they all will have different designs. The E34 525i has two different engines, M20 for 1989 and 1990 and M50 for 1991 to 1995. |

Firstly, my car is the E36, and it could be different than yours, but I
don't think it is different. Yes, there is a sensor about 1/3 of the way up the side of the tank.
