Car Forum / BMW Cars / September 20061998 740iL Question - Urgent - Thanks In Advance
I have a 98 740iL (production date 05/97). I need to replace the coolant temperature sensor. Ordered and received the part from AutoZone today. Opened the hood and I cannot find it (LOL) ... Nothing that resembles the part I have ... Can someone guide to "exactly" where this "COOLANT TEMPERATURE SENSOR" is located on a 98 (production date 05/97) 740iL. I have attempted to find "schematics" on-line without any luck. Much appreciated. Thanks In advance, Cheers. > I have a 98 740iL (production date 05/97). > I need to replace the coolant temperature sensor. [quoted text clipped - 12 lines] > Thanks In advance, > Cheers. What's shown in the picture is not the right engine. It is mine 540 but it is getting a 4.0L from a 740. Hope it gives you an idea where to look. Look between the rear of the engine and the firewall on the passenger side. http://i21.photobucket.com/albums/b274/yaofengchen/BMW_95_540/DSC_2838.jpg yaofeng you ARE a good man! We did not even bother looking at the firewall-end ...! Will tackle this tomorrow ! >> I have a 98 740iL (production date 05/97). >> I need to replace the coolant temperature sensor.

[quoted text clipped - 23 lines] > > > > http://i21.photobucket.com/albums/b274/yaofengchen/BMW_95_540/DSC_2838.jpg I checked the ETK of your 740. It appears the two holes on the coolant distribution header behind the engine where I indicated to you are plugged which means the CTS's are moved somewhere else on E38. So don't be surprised you don't find it tomorrow. If you provide the part number, I am sure others can tell you where to find it. Kyle thanks for the diagram url ... you had this right. The part from the dealer with my BMWCCA discount $15.00 10 minutes to change ... Happy to report that there is a ignificant difference in idling etc ... yes, check engine light gone too. Appreciate the help. Cheers, >> yaofeng you ARE a good man! >> We did not even bother looking at the firewall-end ...!

See part #9 on this diagram... http://www.realoem.com/bmw/showparts.do?model=GJ83&mospid=47531&btnr=11_1535&hg= 11&fg=35 You'll see the water pump its located on right on the front of the engine with the fan attached to it. Kyle. 98 740iL 01 525i
