Temperature Data +2S130

PostPost by: Hawksfield » Thu May 23, 2024 4:00 pm

Having had some overheating problems now sorted. I was never sure of the temp showing on the gauge and decided to investigate what the markings relate in actual temperature.
As I had searched the net for the correct sender unit (TT861101 black) fitted a new one with new thermos stat (74 degree). Flushed the system and filled with Blue antifreeze coolant and distilled water. it now runs cooler and during a 22 mile spirited run it remained around the gauge marking 85.
Got out the decade box and injected some resistance values via the sender lead. the results are attached below

That is useful reference data John. I will file. Thank you for sharing.
The engine in my +2s130 thankfully like your car runs consistantly when up to temperature with the needle at 85 on the gauge.
