Princes town auto supplies. 655 7633Calor wrote:^where do you purchase the ford motorcraft coolant?
Well the ones princes town auto is for diesel and gas. I dont think there is amy difference. But they have the coolant concentrate. You have to mix it 50 50 with de ionized water, basically distilled water or rain water. Do not mix it with regular tap water because the chlorine in it corrodes the internals, causing thermostat to stick, and that kind of disgusting millibug looking thing.Calor wrote:Thanks...is there just one motorcraft coolant or there is a special one for diesel engines?
Sssl guys told me to use radicool by castrol but those guys....

babygirl wrote:Do not remove the thermostat! Replace it every 60,000km with new oem ($295). What happens when u remove thermostat causes more damage. These wl engines are designed to operate at a specific temp.
1. At operating temp the oil thins to allow easier passage through turbo, oil ports and valves etc. Cooler oil is thick and the engine works harder to force this oil through, causing premature wear.
2. The engine can still overheat without thermostat. On longer drives the water does not stay in radiator long enough to cool and continuously heats up because its constantly circulating. The thermostat keeps the water in the radiator for a little while to cool, then when thermostat opens, sends the hot water from engine to cool and sends the cool water to the engine to regulate temp.
3. Without thermostat, the wl engine's glow plugs remain on for a long time even when driving! These glow plugs are designed to stay on when engine is cold to help heat up engine quicker and prevent that loud knocking from a cold diesel engine. Dont believe me? Start the engine and put a test light on the glow plug wire by the rail and see how long it takes to turn off. It usually turns off when temp reaches 1/4 the way. This burns out the glow plugs, and glow plug relay. Engine then sounds old when started, and takes more cranks to start.
4. Without thermostat, the engine rings wear faster, because oil isnt thin enough to lubricate cylinder wall properly. Thus, backpressuring and oil burning.
So guys, lets replace the thermostat and not remove it. Engineers designed it for very specific reasons.

Replacement of the coolant mix according to schedule is more important. Keep an eye on engine temperature. An overheating engine likely has a bad thermostat or blocked radiator caused by age or calcification (calcium precipitation and depost) from the cooling system fluid. Replace the thermostat with a quality, new component that is a direct replacement. OEM parts are not necessary.

Agreed
1. At operating temp the oil thins to allow easier passage through turbo, oil ports and valves etc. Cooler oil is thick and the engine works harder to force this oil through, causing premature wear.
Multi viscosity oil allows an engine to properly lubricate via the pump alone to sub zero temps that never occur in the tropics. Excess wear occurs when there is sludge (dirty/old oil) or during cold start when the oil passages are empty.
2. The engine can still overheat without thermostat. On longer drives the water does not stay in radiator long enough to cool and continuously heats up because its constantly circulating. The thermostat keeps the water in the radiator for a little while to cool, then when thermostat opens, sends the hot water from engine to cool and sends the cool water to the engine to regulate temp.
The engine may operate at acceptable temperatures in the tropics but will likely not warm at all during colder weather. The sole purpose of the thermostat is to allow quick engine warming to about 95°C for cleaner combustion and improved engine efficiency.
3. Without thermostat, the wl engine's glow plugs remain on for a long time even when driving! These glow plugs are designed to stay on when engine is cold to help heat up engine quicker and prevent that loud knocking from a cold diesel engine. Dont believe me?

This burns out the glow plugs, and glow plug relay. Engine then sounds old when started, and takes more cranks to start.
Glow plugs operate prior to engine start to pre-warm the combustion chamber. Compression is the only ignition method in a typical diesel. Glow plugs that are on during run likely have a faulty relay or a resistor protected relay that registers a quiescent voltage.
4. Without thermostat, the engine rings wear faster, because oil isnt thin enough to lubricate cylinder wall properly. Thus, backpressuring and oil burning.
The engine will likely not wear faster but will likely run rich resulting in decreased engine power, soot deposits and black smoke from the exhaust.
So guys, lets replace the thermostat and not remove it. Engineers designed it for very specific reasons.
Yes, we did.
really? cant speak on the glow plugs part but please educate us

he make the glow plugs sound like is spark plugs . i dunno how to feel bout thermostat .cause with it .. it does stick.. without it . u cant use the heater in d ac n well the temperature fluctuates quicker .. i know that from experienceadnj wrote:ru$$ell wrote:adnj wrote:I realize that this is old but there is so much in this post that is absolutely wrong.babygirl wrote:Do not remove the thermostat!
