Truck wasn't heating up, so I knew I had a bad thermostat. No problem, it'* easy to change those. WRONG!!!! WTF, really, did it have to be this hard? Took me a good hour and a half. You can't get at anything. Look at the angles I had to use to get this bolt off.
The other one there was no way to get a socket on it. Even a wrench didn't fit on the open side. I had to use a box end wrench and I was able to get 1/12th of a turn on each stroke. And a gear wrench didn't fit. What a pain.
I had to unbolt the distributer and turn that out of the way. Otherwise I couldn't even get a wrench on it.
Finally got it all done, then moved on to the spark plugs. That wasn't to hard. One plug had a pipe in the way so I had to use a swivel. Otherwise, it went well. Old plugs looked worn but still clean. That tells me the engine is running good.
Next step was my heater blower. It was not blowing much air, and started to bark at me.
Ya, not hard to see why it wasn't blowing much air. I then looked inside the motor, looked about the same. Cleaned that all out and lubed the shaft end. Good air now, lots of heat, and no more barking.
