Any ideas as to why the temp gauge would drop when I get on the gas? It goes all the way down to 100 when I get up to 4k rpm's.
I've been battling an overheating engine since I picked up the XJ a few months ago. I solved that issue by replacing the PO's 180* thermostat with a 195* and fixing the piss poor coolant mix that was in there. It was almost straight coolant so I went ahead and used a cleaner and flushed it and now it's all good.
I was hoping this would have solved my dash gauge issue too, but it didn't. I suspect bad wiring but this may just be an old jeep thing. Not leaking any coolant, no air in the system, though I think my water or steering pump may be going bad as there is a whining like a bearing going bad on startup. I suspect this may cause some cavitation in the coolant and introduce air.
