  1. Here's a topic here about Overheating troubleshooting. Even though the specs are for 626, the general diagnose still applies to most vehicles including Mazda Tribute/Ford Escape.
  2. I don't know every single bolts and screw sizes a 626 has but I can recommend using a tap and die set measuring gauge that measure pitch size of the thread. It looks like a feeler gauge. Take the other axle bolt next to it and measure it with the thread pitch gauge and you'll get the thread size. You just have to find the girth size at your local hardware store by comparing it. If you still can't find it, you could cut new threads into the block with a different bolt.
  3. Mazda Announces Long-Term Vision for Technology Development, ‘Sustainable Zoom-Zoom 2030’ Introduces SKYACTIV-X, world’s first commercial gasoline engine to use compression ignition HIROSHIMA, Japan—Mazda Motor Corporation today announced “Sustainable Zoom-Zoom 2030,” a new long-term vision for technology development that looks ahead to the year 2030. As part of the new technology to achieve this vision, the company disclosed plans to introduce a next-generation engine called SKYACTIV-X in 2019. SKYACTIV-X will be the world’s first commercial gasoline engine to use compression ignition.1 Under the original “Sustainable Zoom-Zoom” vision announced in 2007, the company has striven to offer both driving pleasure and outstanding environmental and safety performance. In light of the rapid changes taking place in the automotive industry, the new vision takes a longer-term perspective and sets out how Mazda will use driving pleasure, the fundamental appeal of the automobile, to help solve issues facing people, the earth and society. The following is an overview of “Sustainable Zoom-Zoom 2030” and the next-generation SKYACTIV-X engine. 1. Sustainable Zoom-Zoom 2030 Mazda believes its mission is to bring about a beautiful earth and to enrich people’s lives as well as society. The company will continue to seek ways to inspire people through the value found in cars. Earth Through conservation initiatives, create a sustainable future in which people and cars coexist with a bountiful, beautiful earth Mazda’s approach ・ Expand measures for carbon dioxide reduction from a “well-to-wheel” perspective, considering emissions over the vehicle’s entire life cycle ・ Aim to reduce corporate average “well-to-wheel” carbon dioxide emissions to 50 percent of 2010 levels by 2030, and achieve a 90-percent reduction by 2050 ・ Achieve this with a policy prioritizing efficiency improvements and measures for cleaner emissions that apply in the real world ・ In line with this policy, continue efforts to perfect the internal combustion engine, which will help power the majority of cars worldwide for many years to come and can therefore make the greatest contribution to reducing carbon dioxide emissions, and combine the results with effective electrification technologies ・ From 2019, start introducing electric vehicles and other electric drive technologies in regions that use a high ratio of clean energy for power generation or restrict certain vehicles to reduce air pollution Society Through cars and a society that provide safety and peace of mind, create a system that enriches people’s lives by offering unrestricted mobility to people everywhere Mazda’s approach ・ Develop more advanced safety technologies under the Mazda Proactive Safety philosophy, working toward the goal of eliminating traffic accidents ・ Further enhance safety fundamentals, such as correct driving position, pedal layout and good visibility, and standardize them across all models ・ Promote further standardization of i-ACTIVSENSE advanced safety features, which help drivers recognize and assess potential hazards; in addition to Japan, where they are already becoming standard, gradually make these technologies standard in other markets starting in 2018 ・ Begin testing of autonomous driving technologies currently being developed in line with Mazda’s human-centered Mazda Co-Pilot Concept2 in 2020, aiming to make the system standard on all models by 2025 ・ Using connectivity technologies, create a new business model that enables car owners to support the needs of people in depopulated areas and those who have difficulty getting around People Enhance customers’ mental well-being with the satisfaction that comes from protecting the earth and contributing to society with a car that offers true driving pleasure Mazda’s approach ž Pursue an enhanced Jinba-ittai driving feel that will unlock people’s potential and revitalize them mentally and physically ž Based on the philosophy of “breathing life into the car,” further develop KODO design to raise vehicle design to the level of art that enriches the emotional lives of all who see it 2. SKYACTIV-X next-generation engine Technological innovations ・ SKYACTIV-X is the world’s first commercial gasoline engine to use compression ignition, in which the fuel-air mixture ignites spontaneously when compressed by the piston ・ A proprietary combustion method called Spark Controlled Compression Ignition overcomes two issues that had impeded commercialization of compression ignition gasoline engines: maximizing the zone in which compression ignition is possible and achieving a seamless transition between compression ignition and spark ignition. Features ・ This new proprietary combustion engine combines the advantages of gasoline and diesel engines to achieve outstanding environmental performance, power and acceleration performance. ・ Compression ignition and a supercharger fitted to improve fuel economy together deliver unprecedented engine response and increase torque 10–30 percent over the current SKYACTIV-G gasoline engine.3 ・ Compression ignition makes possible a super lean burn4 that improves engine efficiency up to 20–30 percent over the current SKYACTIV-G, and from 35–45 percent over Mazda’s 2008 gasoline engine of the same displacement. SKYACTIV-X even equals or exceeds the latest SKYACTIV-D diesel engine in fuel efficiency. ・ With high efficiency across a wide range of rpms and engine loads, the engine allows much more latitude in the selection of gear ratios, providing both superior fuel economy and driving performance. Moving forward Mazda hopes to help create a future in which people, the earth and society can coexist with cars, to enrich people’s lives through a car ownership experience that celebrates driving, and to become a brand with which customers feel a strong emotional connection. # # # 1 As of August 2017. According to in-house investigations. 2 Mazda’s human-centered self-driving technology development concept. People enjoy driving while being revitalized mentally and physically. Meanwhile the car is driving “virtually” with a firm grasp of the movements of the driver and the car. In unexpected situations, such as a sudden loss of consciousness, the car will override the driver, automatically contact emergency services and drive safely to the most appropriate location. 3 Engine is still under development and figures are subject to change. 4 A condition in which the ratio of gasoline to air is reduced to a level that would not ignite in a spark-ignition engine.
  4. Chance of a leaking hose on a junkyard 626 are very unlikely, just make sure you replace with fresh new o-rings. Never had leaking a.c. problem on my 626 and it was at 220k miles.
  5. If you get a catalytic converter below threshold code, your cats toast. You need to replace it. Also important to find what killed it.
  6. Your family has 2 CX-5?
  7. I don't know much or rebuilt the engines on the 1987 626. From my general rule, if there are any excessive clearance on any part of the motor such as the cam clearance and or Main bearing journal oil clearance; its most likely going to cause low oil pressure. Don't forget to consider the possible oil pump failing as well.
  8. How do you know the coolant is not circulating? From a logical point of view, if fluid is not circulating then there is something blocking the system. Narrow down the source, check if there is fluid able to flow through the radiator with a water hose, check your rubber hoses.
  9. Should paint the valve cover. It would look sweet.
  10. Time to check for headgasket leak. Possible that there may be exhaust gas leaking into the coolant system and creating more pressure. There's the normal engine compression tester and there's a headgasket testing tool that comes in a blue liquid.
  11. Sounds like a resistance related issue. When temperature changes, it affects the resistance in the wiring and sensors. You could check fuel injector resistance on each injector, it's been awhile I can't remember, I think the specs should be 14-16 ohms. If its open or too much ohms, it may be a failed injector.
  12. Pressure test the cooling system and see if there any pressure drop. If there is a pressure drop and you don't see it leaking anywhere externally, then you might need to looking at a possible headgasket job.
  13. I would presume that you would also have braking issues first in addition to the vacuum leak from the booster. Especially if you were to push the pedal down, you would hear a whoosh noise like air escaping from the brake pedal area meaning air escaping from the brake booster. Although I would be optimistic of the possibility of it having a vacuum leak and causing rough idle. When you push the brake pedal, the brake lights puts a load on your alternator. If you hold the brakes, does all your lights flicker? If you turn on all your loads or some of it like a.c., dome lights, high beam; does your engine buckle?
  14. What are the codes specifically?
  15. A symptom of a failing brake booster is a hard to depress brake pedal. You have to push very hard for the car to stop.
