240 5.0L swap sensor solutions
Here is a question for the 5.0 swapped guys. Just got my 5.0L freshly rebuilt... the man did a fine job.
Having some electrical issues with the temp gauge and electric fan. I?m starting to think the temp sender is faulty, or just heavily corroded after sitting for 5 months in open air. At first there was no signal. I grounded the wire and the gauge topped out. Good, that mean?s the gauge works and these is a signal. Cleaned up the contacts and now it tops out slowly when plugged into the sensor.
Next step will to pull it out clean in thoroughly replace tab connector. If that doesn?t work I may need a new sensor. I know the one in there isn?t the original sensor so... what fits in a 1989 5.0L and has the proper resistance for a Volvo gauge cluster?
Second. The electric fan set-up runs off a sensor in the radiator that triggers a relay. The fans would kick on at ~200*. Which is fine for a 5.0 that designed to run at 195*... I?m unsure of that sensor even works anymore... I?m wondering if there is a way to wire the relay into the cluster sender.
Side note: we replaced the temp sensor for the ECU with a new NTK. Going over the sensors I noticed one of the posts was melted. Good thing I still have the old sensor... may need a new plug just to be safe. What would cause that?
