I know there is a thread on this further down but it's a slightly different problem.
I'm using temp sender of, VDO: 320003. (blue ring)
The problem is, I don't believe my temp guage is working correctly.
Under all circumstances of driving my temp seems to be permanently stuck on 3/4 (creeps towards 7/8 when at lights).
I left the engine tonight for about ~2 hours [after a fair drive], ignition on and startup and engine is on half temp, within driving ~100m the temp guage had already found the 3/4 mark again, whereby it stays whether highway driving etc.
(also seems to be able to go from dead cold to 3/4 faster than I can feel the engine getting that hot).
Temp guage worked perfectly on my 6 cyl.
She does get real damn hot to the touch after driving awhile, but there's a brand new radiator/fan sitting in front of her and there is no water leakage.
At the moment not using coolant, just straight water, but wouldn't think this would make a -huge- difference (at least not 1/4 of the guage where I'd like to see it!) in the older blocks?
I had the incorrect temp sender on there for about a week (barely ever registered a thing), hoping I haven't damaged my guage or am actually running my engine this close to dangerously hot.
Pulled into my driveway and tempature guage shot up to maximum (before I could even open my door to open gates) - immediately switched off ignition and checked wire - it's not earthing on the block or anything as such - turned car back over to get her inside and guage was at 3/4 again.
[edit] Forgot to mention: This afternoon when I put the sender in, the block was relatively cold and it did read at 1/4 temp.
Naturally when there is more light I will check wiring once more, but I really don't believe this is the problem <_<
Secondly: Does anybody know if an oil pressure sender from a 202 will work with a 308? (Different size threads/read different etc?) as they appear to be identical in shape/size.
Thanks guys.
Got a feeling I'm going to have to investigate some cooling measures in that cosy and toasty engine Bay. (LH)
