So , i've had this since I bought my E36 323i (96) 8 months ago now.
When driving on open road, not a care in the world, soon as I hit a traffic jam, I sit and sweat, fearing the heat needle rising towards redline.
I have bled the radiator and topped up and all good, but today I drive 300 miles or so , stuck in traffic twice, 2nd time was near red lining it and had to do something, wasn't worth pulling over because 5 mile tailback (M25),so I had to absolutely cane it , I was stuck in middle lane , and slip road to my left onto M4 doing 40mph, I love that 6 cyclinder beauty
anyway soon as I hit speed, nearing 40mph, goes straight back to the middle bar = ok.
so, i reckon viscous coupling or fan clutch ?
Anyone had this and know. ? I think knowing the problem/potential solution before you go into the garage is a good thing to avoid being stung, as I found with my last experience. ....
Fan clutch yeah maybe.. park it and let it warm up in your driveway and see if the fan ever engages.. if not, fan clutch is cheap.. or go electric convert for about the same price (maybe cheaper) and gain HP @ the same time.
Another option might be your water pump.. they have notorious failure rates, not positive that effects your '96 but I think that's within the years of the plastic impellor blades that *always* break and require replacement.. maybe just one or two of them shaved off, and it's unable to pump enough water at low rpm. If you replace it, be sure to get a replacement that does not have plastic impellors.
