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. ....
thanks in advance.
