Mazda B2200 Thermostat
The Mazda B2200 Thermostat regulates engine warmth so that the engine does not run too hot or too cold and maintains performance and service life. The device is mounted in the coolant passage close to Mazda's radiator, and it is a closed-loop switch that senses temperature and blocks or allows coolant flow and brings the inline-four to the optimum operating temperature and maintains it there to provide consistent power output and fuel consumption. During the production of the pickup, Mazda applied established mechanical designs that move in direct proportion to heat, and the B2200 truck employed two primary styles. Early trucks had a single simple bimetal strip unit, a matched pair of metals that bend due to heating to permit passage of coolant. Subsequent ones applied the wax-pellet design, in which the wax expands and forces a plunger body away as the setpoint is achieved, providing smoother movement and more precise control. The two types are similar in function but vary in heat detection where the bimetal strip is flexible, whereas the wax capsule is stretchable, and the latter has more resistance to road vibration at high rates. This Thermostat opens quickly when the coolant reaches the set mark and closes when the temperature falls below it to prevent excessive cooling and wear on the engine during cold starts. Despite the fact that home HVAC devices now have programmable screens and wireless connectivity, the rugged Thermostat applied in cars continues to rely on a simple on-off response because the cooling system needs only a quick and reliable reaction. All Mazda owners can thus expect stable self-regulation of the cooling loop of the B2200, since the Thermostat gradually becomes accustomed to sharp ascents, traffic jams, as well as winter mornings.

Mazda B2200 Thermostat Parts and Q&A
- Q: How to remove and install a thermostat on Mazda B2200?A:In order to install/removal of a thermostat, make sure that; in case the replacement one has a jiggle pin, then it must be upwards (towards the top of engine) and that is on the side that is facing the water outlet. In the case of the 2.2L engine, drain coolant under the thermostat housing is on the left front side of the cylinder block, disconnect the temperature sending unit wire and eliminate the coolant outlet elbow. Open the vacuum control valve, which is there as needed, disconnect the coolant by-pass hose, and remove the thermostat and housing. Record the location of the jiggle pin and remove all the gasket material. During installation, place the thermostat with the jiggle pin in the front, place a fresh gasket with sealer on it and fit it on the housing and tighten bolts to 14-19 ft. lbs. Re-attach hoses and fill the cooling system next, ensure that it has no leaks. In the case of the 2.6L 1987-88 engine, drain coolant under the thermostat, take off hoses and housing, throw out the gasket and wipe off surfaces. Install new gasket and thermostat, 15 ft. lbs on bolts. On 1989-93 models, drain coolant, do not use the upper hose and housing, clean surfaces, fit the new thermostat with the jiggle pin upward, and close it with adhesive sealer to 19 ft. lbs. In the case of the 3.0L, the front end should be raised, coolant drained, and the lower hose and casing removed, cleaning off of surfaces and installing a new gasket when necessary and then fit the thermostat and housing and firmly screwed together to 19 ft. lbs. To the 4.0L engine, avoid draining the engine coolant, disconnect battery ground, take out air cleaner duct and upper radiator hose, and disconnect the thermostat housing. Cover the mating surfaces with cleaniness, position the sealing ring, place the thermostat with air release valve in the up position, affix adhesive sealer and tighten bolts to 7-10 ft. lbs.
