91 civic temp gauge
Hi-
Just picked up a '91 civic dx hatch for $150 for the wife to get back and forth to work.. Runs good, a/c works, no rust - a pretty good deal I think. When it was driven home approx. 15 miles and parked, it smelled pretty hot from outside, but temp gauge was in the middle for the whole ride steady as could be..The car had been parked for about 3 months without being run at all during that time. So, I put about $250 into it the next day for battery, wipers, front pads and both sides rear brake wheel cylinders, drums and shoes, 4 quarts max-life, a haynes manual and a new oil filter We put it up on her uncle's lift and started working. I told him about the hot smell driving home the night before, so we pulled the t-stat & he boiled it and found it to be working. Put the t-stat back on and now the temp gauge goes crazy. Goes up and down rapidly, seemingly with no rhyme or reason. it'll show hot (all the way up) when driving at a steady rate, then go back down to the middle less than a mile later, then go to all cold and suddenly shoot back up to the top. This happens while driving at a steady pace, accelerating, sitting still, basically all the time. Did we foirget to plug something back in when we took out the t-stat? He looked at the manual to make sure to put the t-stat back in correctly. Is there a sensor we could've broken? Nothing looks abvioulsy amiss to my eyes. Any ideas? Thanks. -- NoOne "There's a man racing towards third...." Harry Caray |

Wax stats can be adversely affected by boiling them since they can lose some wax and be recalibrated at 100ºC. The way to do it is to heat the pan slowly and remove the heat when the stat starts to open and record that temperature. Of course it may be too late now. The variation and instability is down to not having bled the system to get the airbubbles out. -- Graham W http://www.gcw.org.uk/ PGM-FI page updated, Graphics Tutorial WIMBORNE http://www.wessex-astro-society.freeserve.co.uk/ Wessex Dorset UK Astro Society's Web pages, Info, Meeting Dates, Sites & Maps Change 'news' to 'sewn' in my Reply address to avoid my spam filter. |
