Besides the usual visual, driveability and leak checks, look for:
Engine Oil level: If the oil level is low, chances are the engine uses oil or leaks. Beware of water in the oil (there is probably a cracked block or bad head gasket), or thin, dirty oil with a distinct gasoline smell (this may indicate internal engine problems).
Look for leaks after engine has cooled down, esp overnight.
Pull the transmission dipstick out when the engine is running at normal operating temp. The level should read FULL.
For tge C6 automatic transmission, if equipped, , look for leaks around pan from (front) Pump seal. Dark brown or black fluid that has distinct burnt odor, indicates a transmission in need of repair or overhaul.
Odor may indicate overheating condition, clutch disc or band failure. Use an absorbent white facial tissue and wipe the fluid level indicator. Examine the stain for evidence of solid particles and for engine coolant signs (gum or varnish on fluid level indicator).
If particles are present in the fluid or there is evidence of engine coolant or water, the transmission pan must be removed for further inspection.
I just purchased this 1985 bronco xlt. It’s carbureted so I’m assuming it’s a 351w?? Anyway, It’s been sitting for 12 years in an old Colorado mountain town. Any advice on a first start?View attachment 21339
