[V6-12v] Temp. gage reading low, trouble code 2312

[Lino M. Valadas]

Very true on the timing belt concern.  I had just replaced the timing last
month and felt comfortable working around it, but never-the-less, I failed
to mention: I put nylon zip ties around the camshaft pulleys tying the belt
to them and crossed my fingers it wouldn't skip at the crankshaft pulley.

I give you kudos for being able to remove the bolts holding the engine front
cover with the fans in place ;-)

Thanks for the post

Lino
