No check engine light
***** coolant and probably wrong oil (just bought it)
131k mi (allegedly) --- bought it from some pretty shady Syrian limo company, so who knows
Signs of recent servicing under hood -- all coolant hooses newish and still have clean Motorcraft stickers on em, but the coolant itself is pale blue crap with some hard water salts-looking sediment in it
Occasional slight hesitation pressing accelerator, but otherwise runs fine. MPGs seem correct, fluctuate 14-17 mpg (4x4, EL length)
Should I just change oil and backflush the coolant system, then put in proper gold coolant to start? Or redo the spark plugs immediately as well? Thermostat right away too, or never mind that?
