My 06 GX has cooling problems...I think!
I recently had a bullbar installed (TJM Outback) and about a week before went 4WDing in a bit of mud. After about a week it started overheating up to the red line. No boiling, just the gauge. The engine did seem a bit hot though at the end of a drive.
First thought was that the new bullbar was restricting flow however I doubted TJM could have got it so wrong. I removed the plate which sits over the winch fairlead hole hoping this would help. It may have a bit but I still got overheating.
Someone at work suggested head gasket might have been shot but there was no white under the oil cap.
Next I thought the mud might have blocked the condenser and radiator so I gave it a good squirt with the pressure cleaner for a good 1/2 hr. The amount of mud that came out was amazing.
Results were better with no redlining but I still get the needle creeping up a bit on hot days (30?). Today I changed my oil, air and fuel filters and oil. Tonight it ran with the needle at 1/2 way up which is where it normally sits once it's warmed up. I'm not losing coolant or water.
Now my questions:
Firstly, for those with bullbars (and diesels, better yet the 1Kz), where does the needle normally sit and do you find the needle creeps up a bit now you have a bar?
I want to try taking out the thermostat to see if it changes anything. Stupid question I guess but where is it? And are there any other suggestions?
