All depends on a number of factors... airflow, ambient air temperature, how hard the engine gets worked, etc.
First of all, the "block heater" is actually an oil or coolant warmer. It will heat the engine oil or engine coolant depending on location installed, and works similarly to an electric water heater. The rate and maximum temperature that the heating element reaches depends on manufacturer. Circulation of the fluid it heats also plays into how long it will take to warm the engine. In general, the larger the motor, the longer it will take to warm and the more power it will require to stay warm. A 7.3L engine will have a higher volume of coolant to heat where as a 5.9L engine.
Most likely a defective thermostat.However,remember that there is a lot of metal in the engine block that has to heat up too.
10w30 or 10w40 is fine for all year driving in warm climates
Around 750 rpm with warm engine and in gear.Around 750 rpm with warm engine and in gear.
THERE IS NO GAUGE CHECK IT WHEN ITS COOL TAKE THE CAP OFF AND LOOK IN DO NOT DO THIS IF THE ENGINE IS WARM IT WILL SCALD YOU
Depending on how many cylinders the engine has determines how much oil the crankcase holds. The more cylinders the more oil is needed. Usually there are between 4 and 5 quarts needed for an engine of this size. DO NOT overfill. Add 4 quarts and check the engines oil while the engine is warm. Add if needed.
It will take approximately 30 seconds to 1 minute for a cold (22 Celsius) engine to to be lubricated. In cold (0 - 15 Celsius) weather the oil needs to warm up for a few minutes so that it will flow easily and splash inside the engine.
Hard to start when cold?? Warm?? All the above? How many miles on the vehicle? Fuel filter been changed lately? How many miles are on the spark plugs?
Use the same BRAND that you've always used, but select an oil that is thick enough that the oil pressure light stays off when the engine is warm and at an idle.
It starts better when its warm!
because the engine is cold and you need to keep the engine warm.
Minimum of 10 psi at idle when the engine is warm.Minimum of 10 psi at idle when the engine is warm.
