Ford 302 water flow diagram

We ended up with the system on the left side of your diagram named 302351 with PS and AC except for 2 deviations. If using a Ford Motorsports balancer see instructions included with hardware kit 199002-HFA.

ART-92-G for my dads EL and it specified a flow direction.

Ford 302 water flow diagram. This is the best diagram Ive seen although its simplistic and doesnt show line sizes if I get time Ill draw one and post it. Line sizes Tstat to radiator 1-14 1-12 1-34 Radiator to water pump 1-12 1-34 flow is better if feed is smaller than return original GT40 has 1-34 feed and return many kits have 1-12 on both. I think it flows out of the engine through the upper hose once the stat opens through the rad and out to the waterpump which circulates it through the engine.

Theres also the 90º bypass hose which is always circulating. L The coolant in the radiator coolant recovery reservoir will then flow back into the radiator through the vacuum relief in the radiator cap. Before the T-stat opens the water is circulated through the block and heater core.

As the T-stat opens water starts to flow into the radiator through the top hose to the radiator inlet passenger side top. When using a front sump oil pan you can use Ford part M-6059-D351 STD rotation water pump or M-8501-B50 reverse rotation water pump front cover with provision for a dipstick. The dipstick needs to be in the oil pan with a rear sump application.

The DART blocks do not have a provision for a dipstick. The pump is fed by the lower radiator hose. The water enters the pump there is spunpumped into the engine.

To check this remove the thermostat and disconnect the upper radiator hose. Direct the stream away from the car. Fill the system and start the car with a water hose feeding the radiator.

Water should come out the upper hose. For 1994 and 1995 Ford rated the high-output 302 at 215 horsepower and 285 lb-ft of torque. While still very debatable the power improvement over the 1993 engine was primarily from airflow improvements.

The Ford engineers supplied a larger mass air flow meter which was the same size as. After doing its thing the coolant flows through the upper hose to the radiator where it releases the heat. Then the water pump sends it back down into the engines water jackets to continue the cooling process.

On the sides of the engine are freeze or expansion plugs which are sheet metal plugs pressed into a series of holes in the block. Jul 23 2004. Originates pushes at the water pump flows through the heater core back to the intake manifold.

At the manifold the heater inlet sits next to the engine outlet. Movement of water through the manifold and into the radiator causes a small vaccuum at the heater return line it sucks. They mentioned that even as little as a 3-4 degree temperature difference using the old Windsor design FRPP block and Yates heads played havoc with hp creation cylinder to cylinder timing etc.

The new engine was designed with water jackets and overall coolant flow to have zero difference between all eight cylinders. It illustrates what happened in 1970 on all Ford small-block V-8s. Ford went to a true crossflow cooling system which meant moving the water pump inlet to the drivers side of the engine.

You must have a compatible timing cover to go with the 1970up crossflow water pump on all 302. I got Ford part no. ART-92-G for my dads EL and it specified a flow direction.

However the thermo in it originally didnt. Motor May 2001 Quote. Believe it or not there are actually a bunch of weirdos out there who reckon a six cylinder is the dux gutz.

The water flows through the block around the cylinder bores to the rear. At the rear of the block there are large coolant passages up into the head. There are a few minor ones along the length of the deck but those are low flow speciality cooling holes.

The heads are where most of the heat is generated at. The water flows from the back of the. Windsor Coolant Flow Diagram.

Now you know why its so important to install the head gaskets with the FRONT markings to the front even though one of them will be installed with the FRONT marking upside down. Need to make sure the watercoolant passages are kept open at the rear of the block to ensure the flow as shown above is not. Water flow direction in radiator.

Replaced water pump on 2010 f-150 46 3V engine. Connection for radiator hose. Upper hose connects to thermostat housing and lower hose connects to block at bottom of engine on drivers side.

Rusty OTooleMemberfrom Ontario Canada. You can tell if it is a reverse water pump the belt goes around the wrong way with the back side of the belt driving the pump. With V belts the belt always has to go around the top of the pump.

A lot of cars are like that. Rusty OToole May 31 2012. How to replace f150 heater hoses heater hoses on the ford f150 carry engine coolant to and from the heater core for use in providing heat to the passenger cabin over time these hoses.

Getting the correct pulley set up for a SBF can be trickyFOMOCO this will help sort it out. Alternatively locate the water pump pulley on the diagram on the front of the engine if you cannot find the diagram. Inspect the belt and water pump pulley to determine if the pump is driven by the inside or outside of the belt and you have answered the question.

Casting design also influences the direction Pump Impeller Vane Angle. You can also look at the impeller vanes to understand flow. It is commonly assumed that curved veins cup water.

We ended up with the system on the left side of your diagram named 302351 with PS and AC except for 2 deviations. Due to belt slap Ford added an idler pulley under the compressor and this idler is not shown in the diagram. I do see this idler in your photo however.

What is labeled Idler in the diagram is actually the belt adjustment pulley. In a V-8 the coolant path travels to the rear of the block and then flows forward to the intakethermostat and forced through your upper cooling hose. 95 ford f-150 30250 strange cooling system problem - YouTube.

Install the water pump as shown in Figure 5 below. Make sure the water pump gasket is aligned properly. Secure the water pump using bolts as shown in Figure 5 below.

Torque to 18 lb ft. Install the harmonic balancer. Torque to 90-100 lb ft.

If using a Ford Motorsports balancer see instructions included with hardware kit 199002-HFA. The ports flow better due to their round shape and straight path. This design was first used on the 427 and then in 1968 on a special 302.

These round intake ports were 38 sq. In area at the intake manifold face. The Tunnel Port 302 cylinder heads feature 212 intake and 154 exhaust valves.
