The Mazda Protege make-believe its debut in 1990. Take the old coolant to an automotive fluid recycling center. Many auto parts stores perform this service autonomous. The "LX" trim aligned came principles with the 1.6-liter, on the contrary had an optional 2.0-liter. The "ES" and "MP3" trim levels came one shot fitted with the 2.0-liter. The engines differ slightly, on the other hand the development of replacing the thermostat is the twin for both engines.
Instructions
1. Stand the front of the Protege with a floor jack and slide jack stands under the vehicle's subframe. Lower the Mazda until lone the jack stands facilitate it. Remove the radiator cap.
2. Crawl below the front of the vehicle and establish the filter plug on the backside of the radiator. Field the remove pan under the extract plug. Remove the empty plug with a ratchet and socket and let on all of the coolant to withdraw from the radiator. Change the filter plug and tighten it with a ratchet and socket.
3. Scrutinize the lower radiator hose for any defects, such as cracking, sponge-like motility or visible aging. Interchange the hose with a advanced one whether any defects are commenced. Hint the lower radiator hose toward the engine until you extent the metal housing that connects the hose to the engine; this is the thermostat housing.
4. Remove the two bolts holding the thermostat housing to the engine with a ratchet and socket. Pull the housing from the engine, exposing the thermostat below it. Grab the thermostat and remove it from the engine.
5. Scrape the mating surface on the engine and the thermostat housing with a plastic scraper. This assures a Disinfected mating of the two. Create not call a metal scraper, as this can damage the mating surfaces and conceive a leak.
6. Distance the current rubber thermostat gasket -- included with the thermostat -- all over the limits of the thermostat. Compose decided to limit up the limited Knob on the gasket with the jiggle valve in the thermostat.
7. Corner the advanced thermostat in the thermostat housing with the spring side facing elsewhere. Edge up the Knob in the thermostat gasket with the dent in the thermostat housing.
Unbarred the radiator cap and slowly fill the radiator -- at a degree of approximately 1 quart per minute -- to the top of the filler neck with 50-50 premixed coolant . Extended the coolant reservoir and fill it to the "F" stop with 50-50 premixed coolant.11. Speedy the radiator cap and start the Protege's engine.
Uplift the Mazda with a floor jack and remove the jack stands. Lower the Protege to the ground.
10.8. Install the thermostat housing and thermostat into the engine and tighten the bolts to 14 to 18 foot-pounds with a torque wrench and socket.9.
12. Run the engine until it reaches normal operating temperature. Increase the engine speed to 2,200 to 2,800 rpm and hold it.
13. Shut the engine down after holding the rpm steady for five minutes. Allow the engine to cool and check the coolant level in the radiator. If the level is below the base of the filler neck, repeat steps 12 through 14. If the coolant level is at the base of the radiator filler neck, check the coolant reservoir and add 50-50 premixed coolant until the level reaches the "F" mark. The 1.6-liter engine holds 6.3 qts. of coolant and the 2.0-liter holds 7.9 qts. in total.
14. The embryonic Protege was basically a Mazda 323 -- the maker's entry-level machine -- with distinct upgrades. In 1995, Mazda dropped the 323 from its lineup and the Protege remained as Mazda's entry-level vehicle. The 2001 Mazda Protege came in four leading trim levels: "DX," "LX," "ES" and "MP3." The "DX" trim calm came fitted apart with a 1.6-liter, four-cylinder engine.
