I have an '89 touring with an M52 swap. Swap was done professionally for the previous owner, so I don't know all the details, but here is what I do know:
-no A/C (never did have)
-no aux pusher fan (possibly never did?)
-clutch fan w/no shroud
-not sure what rad or fan
When I picked up the car it made good heat and the temp gauge read normal. Shortly thereafter it stopped making much heat and took a long time to warm up. Whatever, no big deal, I popped a new thermostat in it and full heat returned. I put in thermostat P/N W0133-1627833, which should be for a '96 328i (the donor car), ordered from here: http://www.autopartsway.com/AutoPart...=W0133-1627833
The temp gauge now typically reads between say 60 and 70% when warmed up (on the high side of that spectrum when idling, on the low side at speed). We haven't had any really hot days here yet, but so far the temp readings are consistent, but high. Do I have the right thermostat? Is there some issue where the gauge reads high due to sensor differences for example? Do I simply need a fan shroud? This is what my rad looks like:
