| Coolant temperature senders - mystery solved (or at least resolved) |
Subject: Coolant temperature senders - mystery solved (or at least resolved) by djxib on 2013/1/21 23:08:54 When I put the refreshed motor in my car over a year ago, I broke the coolant temperature sender (the one that goes into the passenger side head). Because I have LT4 heads and intake I ordered a 1996 sender. (My car is a 1992). Since that moment my analog gauge has read 30-40 degrees hotter than the digital readout on the dash. I tried reburping the coolant system a few times but it was consistently higher. So today I decided to take advantage of the MLK holiday and I changed oil and did a coolant flush - I also bought 2 new sensors (water pump and passenger head), Voila - the analog gauge now tracks with the digital gauge (or at least the best I can tell given the gauge markings). It also behaves exactly like it used to before the refresh. So I wont freak out every time the digital gauge shows 200 (because the analog would previously show 240 ish). The problem was either: 1. Inadequate reburping 2. A bad sender from the factory or.. 3. the 1992 sender is calibrated differently from the 1996.. Thought I would share. |
