What size is my heater hose?
If you need to replace heater hoses, measure both the length and inside diameter of the old hose. Heater hose comes in ½-, 8- or ¾-inch sizes and is usually sold by the foot. On some cars, the inlet hose could be a different size than the outlet hose, so don’t measure only one and assume they’re the same.
How do I know what size radiator hose I need?
Hoses are always measured by the I.D (inside diameter or bore). This is the important measurement. The outside diameter may sometimes be quoted in a technical drawing or such like, but this is not as important. Hoses are measured by the I.D because they fit over a metal/solid tube.
What is the outside diameter of 5/8 heater hose?
This is ⅞ Outside Diameter hose!
Can you use fuel line as heater hose?
No problems. I did some research at that time and it looked like fuel hose was resistant to antifreeze and was rated for a high enough temp. So, fuel hose can handle antifreeze, but not vice versa (radiator hoses can’t handle gas). And as bennie said, make sure you use FI rated fuel hose vs low pressure stuff.
Is heater hose the same as coolant hose?
Coolant hoses and heater hoses are essentially the same thing, but applied towards different purposes. Coolant fluid, like Freon, is much more effective at cooling an engine (and heating a car) than regular water, because water boils and freezes much faster than Freon.
What size is car radiator hose?
On traditional muscle-car V8 engines, typically the lower radiator hose should be about 1438-inch larger than the top hose (for example, if the top hose ID is 1 Inches, the bottom hose usually measures 134 or 178 inches).
Is 5/8 garden hose ID or OD?
In the United States, most standard garden hoses are 5/8 inch in diameter. The bigger the diameter, the more water is delivered.
What is the ID of heater hose?
Standard Heater Hose 5/8″ I.D. (Sold Per Foot) CQ1726: Advance Auto Parts.
What is the outer diameter of 3/4 heater hose?
1.07 in
Technical Information
| Size | 3/4 in |
|---|---|
| Hose Inner Diameter | 0.75 in |
| Hose Outer Diameter | 1.07 in |
What size fuel line do I need?
Recommended Size, Based on Horsepower
| Recommended Fuel Line Size (from the tank to the pump) | ||
|---|---|---|
| Engine Output | Size (inches) | Size (AN) |
| 350 hp or less | 5/16 in. | -5 |
| 350-450 hp | 3/8 in. | -6 |
| 450-650 hp | 1/2 in. | -8 |
Can you use heater hose for EVAP system?
Don’t take a chance with anything that is not rated for gas. Most heater hose can chemically handle gasolene, however the problem may be if it can handle slight negative pressure or partial vacuum in the tank without collapse which would cut off any venting flow.
What size are most radiator hoses?
The most common sizes of heater hose are 5/8″ and 3/4″. Inside a heater hose you can see the edges of the cords. Note the thin wall and sparse cord, this is low-pressure stuff. Radiator hoses are also lined with cords, but they are molded to shape.
Does coolant hose size matter?
The smaller an orifice’s cross-sectional area for a given flow volume, the higher the vacuum—so the lower hose is typically made larger than the top hose to minimize suction/vacuum at the pump inlet, as well as to allow sufficient fluid volume to reach the pump so it can produce proper pressure on its outlet side.
What size hose do I have?
Hose Diameter The measurement you see on the packaging represents the inside diameter of the hose. ⅝ inch is the most common and a good diameter for adequate water flow and pressure. Garden hoses also come in ½ and ¾-inch diameters. The larger the diameter, the more water the hose can hold.
What is better a 5’8 or 1/2 hose?
1/2 inch hoses are ideal for light gardening tasks such as watering plants and hanging baskets. On the other hand, 5/8 inch hoses are ideal for tasks and applications that require high water pressure such as pressure washing, car washing, and sprinklers.
Why is there no heat on my 4th Gen F-body?
This is the #1 cause for a no heat complaint on a 4th gen f-body. Remove the heater hoses at the water pump. This allows flushing of the hoses andthe core. Orient the hoses to keep all moisture off the optispark. Using a garden hose, flush into one heater hose allowing the water to come out the other.
How much coolant does the 4th Gen F-body take?
LT1 coolant capacities for the 4th gen F-body: With Manual Transmission – 15.3 quarts (14.5 L) With Automatic Transmission – 15.1 quarts (14.3 L) Close bleeder screws when bubbles disappear and only coolant is visible. Fill the coolant recovery reservoir to the COLD fill mark.
What thermostat does the F-body LT1 use?
(see “dual fan configuration” below about primary and secondary fans) The f-body LT1 uses a 180° thermostat as stock. Crusing temps are generally 10°-20° higher than the thermostat rating. The PCM gets it’s temp readings from a sensor that is in the water pump.
How much warmer is an LT1 thermostat than the temperature rating?
While crusing on a moderate temperature day, an LT1 will generally run 10°-20° warmer than the thermostat temp rating. Make sure you use the correct, long LT1 thermostat (not an SBC thermostat) as described in the troubleshooting section above.
