Mar 23, 2019 · Coolant Flow Diagram. Originally Posted by BimmerBreaker. The upper hose is the hot hose on every BMW I've worked on. Makes sense to me, heat rises after all, so have the hot inlet on top of the radiator and take the cool coolant out at the bottom. I also imagine you'd want the sensor on the cold side of the thermostat. The water pump contains a centrifugal impeller, which spins rapidly and creates a suction force that draws coolant into the pump’s inlet port. These blades push the coolant through the pump’s outlet hose and into the engine block. The impeller blades are engineered in a way to create a steady flow of coolant, even at low speeds.The primary job of the cooling system is to keep the engine from overheating by transferring this heat to the air, but the cooling system also has several other important jobs. 4. The engine in your car runs best at a fairly high ... temperature, the thermostat blocks the coolant flow to the radiator, forcing the fluid instead through a bypass ...With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank. Air locks in the Northstar engine shouldn't be a problem as the system is self purging, given that all hoses are clear.

The coolant flow diagram for the 7.3 Powerstroke can help you troubleshoot any problems you may be having with your cooling system. The diagram shows the path of the coolant as it flows through the engine, radiator, and hoses. It also shows the location of the thermostat and how it controls the flow of coolant. · N52 Coolant Flow Diagram. Attached is an example of a Coolant Flow Diagram. This is a screenprint from BMW Training Manual ST501 Engine Technology, Part 04 Engine Mechanical, page 33. It is for the N54 engine. What I am asking for is ANY cite or link to a similar Flow Diagram for the N52 engine.Water in the block and heater circuit flows constantly - the thermostat housing mixes coolant from the heater and block circuits until temps come up to design spec (188) and the thermostat begins to open, allowing coolant to flow to the radiator in small amounts - as temps come up the system stabilizes and MOST of the cooling is done by the heat...When you slow down and there's not enough air flow through the radiator, such as sitting in traffic or idling in your driveway, the cooling fans regulate the engine coolant temperature. The proper thermostat for a Northstar V8 is a 195 degree T-stat and the best brand to stick with is AC-Delco when it comes to replacement.

Submariner409 Administrator · #2 · Aug 26, 2015. There is absolutely nothing wrong with DEX-COOL (or any other coolant) as long as you properly maintain the system and change interval recommended. Personally, I would change coolant - ANY coolant - every 3 years, religiously. The car runs DEX-COOL, the truck runs Ford Coolant - a similar long ...The pump circulates fluid whenever the engine is running. The water pump uses centrifugal force to send fluid to the outside while it spins, causing fluid to be drawn from the center continuously. The inlet to the pump is located near the center so that fluid returning from the radiator hits the pump vanes. The pump vanes fling the fluid to the ...December 1, 2022. The Ford 4.6 coolant flow diagram is a great resource for anyone who needs to know how the engine cooling system works. The diagram is easy to follow and shows all of the major components that make up the system.

Jan 21, 2017 · Written by the Northstar System powertrain engineers. Northstars with failing head gasket(s) usually do not mix oil/coolant or vice versa. They simply overpressure the cooling system, blowing off coolant, overheating the engine due to no coolant flow. Learn to speak coolant "purge line" and go from there.  · A bit of surfing will find illustrations of every sensor/module ON a Northstar. If yours is a '99 the main difference is the ICM - yours would use a single board under the 4 coils - 2000 and later use 2 ICM's, each in a leg of one of the two 4-coil ignition cassettes.
