We installed a bunch as they came through. Some slipped through the cracks? Or people changed the tank and didn't understand the purpose? Who knows?

R.E.D Posted August 29, 2019 Author Share Posted August 29, 2019 Only thing I see that's bothering me is that my oil and coolant temp gauges are staying around 160 degrees .they are usually around 185 for coolant and 200 for oil.wonder if the new ecm had gauges with different resistance values ??

Oil doesn't cause corrosion, it prevents it. So even if it does occur it won't cause the same damage the coolant will. Quote Link to comment Share on other sites More sharing options...

I thought as much.i reckon all the chemical components in coolant along with the 12v power coming from those pins acted like an electrolysis machine and just ate them up.

SurvivorMark84 Posted June 16, 2022 Share Posted June 16, 2022 Check for the wiring near the driver side battery box. It tends to short out rubbing against a bolt due to poor placement. It will shut down everything and if it's an mdrive give you the stars. If not there check the fuses one inside behind the speedo it's a 10a and the other is a 20a above the radio.
