Electric water pump conversion
From : trey
Q: has anyone put an electric water pump and radiator fan on a 99 dak 5.2 4x4 auto trans when i go 4x4ing i am not hauling a$$ i am usually going 5-20 mph tops. while climbing the hills when its hot out my truck gets very close to overheating. the gauge reads 210f. im thinking the water pump and fan are just not moving enough water and air to cool the engine enough since i am usually in a pretty low rpm the whole time. thinking an electric fan and pump to keep the cooling up and an auxiliary oil cooler. also will i need to upgrade the alternator to accommodate the addition of the electric pump and fan and does anyone make a bigger/thicker radiator for the dak .

i dont see what you are worried about 210f is not a real problem. my truck has been running between 200 and 210 from the day i got it new with no problems. if you have the proper amount of coolant 210 is not close to overheating. -- if at first you dont succeed youre not cut out for skydiving has anyone put an electric water pump and radiator fan on a 99 dak 5.2 4x4 auto trans when i go 4x4ing i am not hauling a$$ i am usually going 5-20 mph tops. while climbing the hills when its hot out my truck gets very close to overheating. the gauge reads 210f. im thinking the water pump and fan are just not moving enough water and air to cool the engine enough since i am usually in a pretty low rpm the whole time. thinking an electric fan and pump to keep the cooling up and an auxiliary oil cooler. also will i need to upgrade the alternator to accommodate the addition of the electric pump and fan and does anyone make a bigger/thicker radiator for the dak .

i would possibly look into replacing the fan clutch if anything. when was the last time the coolant was changed and flushed you should be able to push 260 at sea level before worrying about a boil over provided the coolant is still good and the radiator cap is still maintaining pressure. -- if at first you dont succeed youre not cut out for skydiving tbone wrote i dont see what you are worried about 210f is not a real problem. my truck has been running between 200 and 210 from the day i got it new with no problems. if you have the proper amount of coolant 210 is not close to overheating. it was still climbing past 210 with the heater full blast the it was about a 4% grade. just how hot can i get that thing before i really have to worry has anyone put an electric water pump and radiator fan on a 99 dak 5.2 4x4 auto trans when i go 4x4ing i am not hauling a$$ i am usually going 5-20 mph tops. while climbing the hills when its hot out my truck gets very close to overheating. the gauge reads 210f. im thinking the water pump and fan are just not moving enough water and air to cool the engine enough since i am usually in a pretty low rpm the whole time. thinking an electric fan and pump to keep the cooling up and an auxiliary oil cooler. also will i need to upgrade the alternator to accommodate the addition of the electric pump and fan and does anyone make a bigger/thicker radiator for the dak .

increasing the rate of water flow will actually increase water temp. if flow is too fast water will not remain in the radiator long enough to transfer heat. sorry but thats all bullshit the man needs an aluminum radiator thinner rather than thicker to increase the airflow over the core to remove the heat a thicker radiator restricts airflow at low speeds increasing heating and 260 degrees with cast iron heads is way too hot politics the gentle art of getting votes from the poor and campaign funds from the rich. .

with a 50/50 mix you should be able push 250f even at 6000 feet. i would not trust an electric water pump for road use and they are not cheap. turn off the heat and see how hot it gets going up that hill. how fast do you climb these hills -- if at first you dont succeed youre not cut out for skydiving tbone wrote i would possibly look into replacing the fan clutch if anything. when was the last time the coolant was changed and flushed you should be able to push 260 at sea level before worrying about a boil over provided the coolant is still good and the radiator cap is still maintaining pressure. had the coolant changed and flushed almost a year ago. the hills i am in start at about 100 feet above sea level and go to about 6000 feet .

do you have a tranny temp guage i suspect most of your problem is from heat transfer from the tanny core to the radiator. increasing the rate of water flow will actually increase water temp. if flow is too fast water will not remain in the radiator long enough to transfer heat. an electric fan might not really help most of the time with a fan clutch at speeds over 30 mph they actually freewheel. gary carter has anyone put an electric water pump and radiator fan on a 99 dak 5.2 4x4 auto trans when i go 4x4ing i am not hauling a$$ i am usually going 5-20 mph tops. while climbing the hills when its hot out my truck gets very close to overheating. the gauge reads 210f. im thinking the water pump and fan are just not moving enough water and air to cool the engine enough since i am usually in a pretty low rpm the whole time. thinking an electric fan and pump to keep the cooling up and an auxiliary oil cooler. also will i need to upgrade the alternator to accommodate the addition of the electric pump and fan and does anyone make a bigger/thicker radiator for the dak .
