Anyone got a spare coolant temperature sensor? Need one fast.
part number 4848110
Been doing a bit of work!
changed the thermostat, went to undo the 3 bolts holding the thermostat housing and this happened!
Note: busted bolt! Not Good
Head of the bold just twisted clean off! WTF!
Took me almost two days to get the broken part of the bolt out.
Tried putting a set of grips on it, that didn't work
Filed top of bolt flat then using centre punch made a hole it the top of the bolt, used various size drills to drill down centre of bolt and slowly increase diameter to get out to the bolt threads,
Taped into the bolt using hardened reverse thread easy outs. Guess what happened next? Yep they snapped off down inside the bolt hole! Arrrrrrrrgh
More new drills needed to remove the so called easy outs! Finally after removing the bloody easy out I used a dremel tool with a small diamond grinding bit to slowly get out to the bolt threads. I managed to remove about 3 of the threads but the rest were not going to come out so had to retap the hole.
I did not have the correct tap tool so made my own. I used a old bolt with the same size threads and cut a vertical slot in the threads which would act as a cutting tool, using lots of lube and pressing down onto the bolt rotating it back and forwards I cut an thread down the hole.
What a PIA. But all done without needing a helicoil and the block saved.
All cleaned up, new 180 thermostat
Used a small amount of holarmar blue gasket jointing compound, (you don't have to but I don't trust gaskets by themselves).
Now need a temp sensor.

And were ALIVE again. I have been having trouble with the Low speed fan not coming on and relays not working,
It seems that the coolant temp sensor sends a message to the pcm which in turn switches the relay to generate the low speed fan.
Having removed the temp sensor I noticed that one of the 4 pins was all black! I cleaned this up with a needle file and refitted the sensor. Bingo Bongo, the relay for the low speed fan is now working!
New coolant added and new 180 thermostat. New 15-50 mobil 1 and job's a goodn!
Temp gauge needle is now sitting at 12ock dead centre and oil pressure is slightly better too
