Hi all,
I need to purchase a new thermostat for my 1988 730i. I found this one and it has good reviews.
https://www.sparesbox.com.au/part/da...ermostat-dt62b
I am wondering if it will fit an M30 engine 730i?
The specifications say it will fit a 735i.
I cannot find a thermostat for the 730i anywhere in Australia - only for the 735i.
Thank you.
spec says under compatible vehicles also BMW 7 Series 730 i,iL (E32) 1990 - 1994 Year 1990 - 1994 Series 730 i,iL (E32) , also E28, E34, 91 Degrees C
based on ETK it would be Thermostat 80CEL 11531710953 , fits many engines https://www.ecstuning.com/b-genuine-...c/11531710953/
and that has these dimensions , compare with the dimensions shown in your link https://www.daparto.de/Teilenummernsuche/Wahler/423580d
The one you found is too expensive, google for Wahler Thermostat 4235.80D , for example on Ebay you can find them much cheaper incl. shipping to Aus. and Wahler is a good brand

Ebay Aus has a Gates t-stat for $54 and they says it fits E32 730 M30B30 https://www.ebay.com.au/itm/Gates-TH...UAAOSwSbxbSA7M

That shop Extra Mile Auto Parts in Dandenong South, Victoria has a lot for E32 and it located in AUS https://www.ebay.com.au/sch/m.html?_...w+e32&_sacat=0

Thank you for the information.
I have purchased the $54 thermostat that you sent. However - there is one problem. I took out the thermostat housing today, and unfortunately the bolts were very rusted and the head snapped. I extracted them using a screw extractor, but i don't know where to buy new ones. The ones i am talking about are the 2 very long ones that hold the thermostat cover on the housing. Any ideas?

always use the ETK with your VIN, so there are Hex bolt with washer 07119915046 M6X25-Z3, and the long ones are 07119912288 M6X70-Z3 http://bmwfans.info/parts-catalog/E3...ostat_housing/ picture https://www.ecstuning.com/b-genuine-...t/07119912288/
take the rest of the snapped ones, there you can see the pitch, go to a hardware shop in town and buy 2 x bolts M6X70 and washers, easy. I assume the pitch is 1mm for M6, but better check on the old ones.
Fits: BMW Hex Bolt with Washer For M5, E34, E32, 750iL, 740iL, 740i, 735iL, 735i, 730i, 730iL, 540i, 535i, 530i, 525i
