How many thermostats does a 7.3 have?
There are 2 thermostats to allow the engine to warm up faster. The top Tstat is pretty standard and controls passage to the radiator. The bottom Tstat has a bypass (if closed) to allow coolant to get back to the pump which allows coolant to bypass the radiator. That is how the engine warms up quicker.
What would cause a 7.3 diesel not to start?
Injector Control Pressure Sensor: When an ICP is failing, the engine runs extremely rough as load is imposed (under throttle), and the condition can eventually contribute to a 7.3L's inability to start. Oil contamination in the wiring usually is the cause.
What is a 7.3 Powerstroke?
7.3 Power Stroke. ... The Power Stroke is an electronically controlled, direct injection engine with a 4.11 in × 4.18 in (104.4 mm × 106.2 mm) bore and stroke creating a displacement of 444 cu in (7.3 L). It has a 17.5:1 compression ratio, and a dry weight of approximately 920 lb (417 kg).
What temperature should a 7.3 Powerstroke?
203° IS THE TEMPERATURE THAT NAVISTAR DESIGNED YOUR TRUCK TO RUN AT. THIS IS THE THERMOSTAT THAT WAS AND STILL SHOULD BE IN EVERY POWERSTROKE 7.3L.
How cold will a 7.3 start?
A healthy 7.3 was designed to start unassisted down to -30C and I've personally started mine down even lower. The glowplugs stay on long after the Wait to Start light has gone off. In winter temperatures they will stay on up to 2 minutes.
How do I know if my 7.3 IPR valve is bad?
A key indicator of a bad IPR valve is low injection pressure. Symptoms of a bad 7.3 Powerstroke IPR can range from running very rough to a no start situation. The symptoms can sometimes feel like you have multiple bad injectors, among other things. You can easily and inexpensively resolve this problem.
How many miles will a 7.3 Powerstroke last?
Robust, iron parts, conservative power and low engine speed are the key ingredients for any diesel engine lasting forever—and if a 7.3L has gone unmodified yet been well maintained its entire life, 400,000 to 500,000 miles is virtually guaranteed.
What Powerstroke to avoid?
The 2003-2007 Ford Super Duty 6.0L may be the worst diesel truck of all time. The 6.0L Powerstroke is infamous. The engine is so bad that Ford and Powerstroke parent company Navistar were engaged in a serious legal battle.
