They both are Ford ranger but one a stick shift

I flushed it out 4 times. changed radiator and thermostat 2 times.overheats within 5 to 10 minutes. it ends up filling overflow and boiling to a hot enough temp to were it is boiling.

It's like the old shifting modules in the old cars is not working

Has been doing it for awhile

The heater is not working as well

For tailgate

what step should I take next?

Slipping from high gear to low slow to shift and at times it'll hard shift

Ac blowing hot air keep adjusting hot cold knob then finally a good rap on top of dash then I get cold air

sounds like the seat belt isn't attach that kind of sound and wont stop doesnt matter if its a long trip or short trip

If u hold pedal to floor it stalls and pops and cracks till it dies

Only getting 6.7 volts

Left head just replaced

How to install brake master cylinder and properly bleed brake system for 1992 does rangerwith an automatic transmission 2 wheel drive 4.0 liter engine? Thank you.

Bank 2. And lean

Transmission manual v6 3.0 liter. Great clutch out of no where it drops out of folirst now at first seemed like it was battery loss of power then only way it would go in gear was turn offf out in gear and attempt to accelerate

Ive changed plugs and new fuel pump it sat for 5years

My truck is a 1994 ford ranger 2.3 liter 4 cyl. 2WD automatic tranny, truck has been running pretty good, but just yesterday It started making a really loud whistle like a boiling tea kettle when accelerating, if I let off accelerator it stops, what could be the problem?

Started out brake lights would not shut off about a hour or so they went off when truck was off but now no brake lights at all replaced switch checked fuses ,bulbs there's no power going to brake lights what do I to.

New battery, new alternator, new clutch safety switch.
Was not starting (no crank) intermittently. Battery tested "Bad Battery" and replaced. Started fine for two weeks then nothing. Same problem. Battery would no longer jump and deep testing showed bad battery. Replaced with another new battery and new clutch switch. Thinking it may be a short in instrument cluster somewhere.
All fuses and relays good.
Short somewhere although no battery drain.
Starter- but no sounds whatsoever.
Note: three years ago instrument cluster was replaced by Ford Dealer. Horn does not work and turn signals won't work until temperature warms up.
Cannot jump but will start with clutch pop.
Any help on troubleshooting procedure would be deeply appreciated.
