i cant really afford a scan or ultra gauge but what is everyones opinion about pulling the engine drain plug putting in the right adapter and installing a temp gauge sensor and mounting it on an a pillar pod if they exist or under the dash if they don't. it scares me to want to change the coolant and no way to monitor the temp
thanks for your input guys
In answer to your question.... 'What is everyones opinion about pulling the engine drain plug putting in the right adapter and installing a temp gauge sensor and mounting it on an a pillar pod if they exist or under the dash if they don't.' Forgetaboutit
I understand your budgetary constraints.
Albertlastsmart hit the nail on the head above with post # 7 a wireless OBDll reader.
For $21.99 I ordered a BAFX Products OBDll Diagnostic Interface. (There are cheaper ones under $10 !) on the internet. I spent a little more because it came with a 2 year Warranty and I wanted to deal with a company that had U.S. based offices.
I had a old small android smart phone that had WiFi and bluetooth. Cost $0.00
For $4.95 I got the Torque Pro App. OR you can use the FREE version of Torque Pro if yo need to save even more.
I have different screens for each of our 4 vehicles. I just unplug the OBD reader and plug it into another car.
Why go through the hassle of having to wire something that may or may not give you the right info, when for under $30 you can plug something into the OBDll port and it will give you a whole lot more that just the coolant temp. Plus you can use it in whatever car you want.
Check out the pictures.
You can have Gage, Graph or Digital display...
Remember BIGGER PHONE = BIGGER DISPLAY
Mine is a little harder to read because I have a convertible with the top down, thus more glareon the screen. I'm sure I could put a small visor on the top of the phone to provide shading.
