How the exhaust temperature of Heavy Diesel engine is Controlled?
The main reason for exhaust temprature is the problem with the injectors.the unburnt fuel from the combustion chamber flows to the exhaust manifold while engine works.This unburnt fuel burns in the exhaust manifold burns and causes high exhaust temprature.
99 Taurus 3Liter replaced plugs wires and vehicle speed sensor STILL have poor fuel mileage What is the problem?
Possibly the O2 sensors need replacing. There's one in each exhaust manifold.
What would cause water to leak out at exhaust manifold and tailpipe at same time?
A broken piston ring is the most common cause of water in the exhaust manifold. A bad valve in the cylinder head can also cause the problem.
Smoke coming out from front of intake manifold on 1990 F150 truck?
If you aren't hearing a lot of exhaust noise and you're just getting smoke, you have either an oil leak or antifreeze leak that is getting on the exhaust manifold. If you're getting oil on the manifold you have a fire hazard and should take care of the problem immediately. If you hear exhaust gas leaking around the manifold you need to replace the gasket or possibly the manifold is cracked and you need to replace the manifold.
Coolant leaking into lower manifold Taurus?
A blown head gasket can allow coolant to see into the manifold, and out the exhaust. A broken piston ring can also cause this problem.

How do you know if the injectors not working on a f350?
Feel the exhaust manifold at each cylinder as it is running, if an injector isn't working the manifold at that cylinder exhaust port won't get hot. Some of those Ford diesels had a problem with the electrical connection where the injector harness passes through the valve covers.
Why would a 2000 Explorer lose power and the cab fill with smoke and smell of sulfur The manifold was glowing red Is this a Catalytic Converter problem?
It could be running lean. Check the fuel filter. It could also be a vacuum leak or the EGR valve. It would probably be a good idea to not run it much until you've worked out the problem. There are quite a few possibilities, and some of them are not very expensive, but if the exhaust manifold is getting that hot you could be damaging your exhaust valves. If the exhaust manifold is glowing, it's not the cat-converter.
