Thermostat: so simple...so complicated
It's something I know I need to be doing very very soon...since the Trep has been using coolant over the past several months. Fortunately nowhere near as much as it MIGHT since I've been driving my 81 Toy p/u since it gets better mpgs (though since November thats been questionable).
My oil has remained that...oil. The crankcase has not yet become a milkshake blender. Around the thermostat cover I did notice some of that gummy green stuff left behind when coolant evaporates and even a wet spot from time to time. NOW...replacing a thermostat SHOULD be an excruciatingly simple job to someone who knows how to use a wrench//ratchet. But there is a problem; I can't get to the 2 rear tiny bolts. There is a wire harness in that nylon wrap that is tucked in the crevice between the thermostat cover and the mushroom-head of the intake plenum. The R/R bolt is just BARELY visible and I might be able to get a socket on it but the R/L one is completely covered. I MIGHT be able to get enough slack in that bundle if I could pull the funky looking plastic clip that is used to hold the bundle onto a bolt stud tip thats buried between the valve cover above cyl#4 and the intake plenum...I'd probably need really long needle nose just to reach down there. Unfortunately the space between the thermostat cover and the intake is about half the size of the wrapped up wire.
Took it to a mechanic to get his opinion: Need to pop the intake so I can move the wire harness out of the way of the bolt to access the bolts holding the thermostat cover on. Anyone else ever had the issue where the wire bundle (at the very least it holds the coil wires for the entire right bank together)...goes around in front of the intake to tuck between intake & thermostat...then continue on towards the left bank? To me, having to pull the intake just to clear up the slack in some wires to get access to a couple small bolts is a bit overkill...
EDIT: On 2/18 I FINALLY got it all paid off..bye bye tax return...so now I own the car bumper to bumper and is the LAST time I buy from a dealership thats for sure.
