To change the thermostat in a 1991 Mazda B2600I, first, ensure the engine is cool and disconnect the negative battery terminal. Drain the coolant from the radiator, then remove the upper radiator hose and the thermostat housing. Take out the old thermostat, clean the mating surfaces, and install the new thermostat with a new gasket. Reassemble the housing, reconnect the hose, refill the coolant, and reconnect the battery before starting the engine to check for leaks.
Where is the fuel pump located at in a 91 Mazda b2600i
on the firewall passenger side
just replace the whole caliper.
The B2600i does not have a pickup coil, it uses a hall effect sensor located inside the distributor to trigger spark. K6 Mazdatruckin.com
See if your public library has a Chilton's for your car to replace the clutch.
Mazdatruckin.com has a schematic for the B2600i vacuum lines in their tech section, it includes 4wd and cruise control devices. See the attached links below.
There is nothing to "check". Look in the owners manual and change the belt according to the service requirements. They never "look" bad until they fail and destroy the engine.
follow the upper radiator hose
Very possible. That info could be found in the owners manual also.
Firing order is usually 1-3-4-2. So start from the front of the pickup, going clockwise. (mine is a 1991 Mazda b2600i).
i would say 30 - 45 minutes to leave a good amount of time. maybe 1 hr if you have problems
Attached in the links below are diagrams for the factory radio and the related dash panels to remove it. I've also posted some additional links for future reference.
