What does the bypass hose do on a 1996 dodge ram 1500 5.2?
When the thermostat is closed, the coolant circulates through the bypass hose from the water pump to the block.When the thermostat is closed, the coolant circulates through the bypass hose from the water pump to the block.
What passage allows coolant to circulate within the block when the thermostat is closed?
Bypass
What does a coolant bypass valve do?
A bypass solenoid valve speeds up the warm up phase of an engine, and a faster temperature rise in the passenger compartment is achieved.
What is the purpose of the bypass hose on a dodge ram 5.7Litter 1994?
To allow coolant circulation through the engine when the thermostat is closed.
How do you replace the coolant line that runs across tho block from behind the water pump?
It's not really a coolant line. This is the intake manifold itself with the thermostat housing and the bypass to the other side of the engine. Unfortunately when Ford made this part it was made of plastic, and in time cracks, hence a coolant leak. You have to replace the intake for this job. Takes anywhere from 6 to 8 hours for the job, plus the cost of the part. The new part is modified and is cast metal.
How do you replace the thermostat on a 2001 Nissan maxima GLE?
* Disconnect the negative battery cable * Drain the coolant from the radiator and the engine block * On SOHC engines detach the upper radiator hose from the coolant outlet at the intake manifold and the radiator then unbolt the hose clamp at the timing belt cover and remove the radiator hose.Detach the bypass hose from the thermostat cover * On DOHC engines remove the drivebelt and the idler pulley bracket.Also remove the lower radiator hose and the water pump drain plug from the side of the block which faces the front of the car * Remove the thermostat cover from the engine.Be prepared for some coolant to spill * Remove the thermostat noting the direction in which it was installed and remove the thermostat
What should you check first if you have no leak and changed the thermostat in 97 escort and have no heat?
I had no heat in my escort either. A new thermostat, cooling system flush, new heater core, another new thermostat, ect. but nothing worked. Still only slightly warm air from the vents. The thermostat housing has a thermostat bypass in it. This bypass is always circulating coolant through your radiator. I plugged mine off with a thermostat gasket and now my car heats and blows hot air with no complications. Good luck.

What is the purpose of the bypass hose?
I will assume that is in an automobile. A bypass hose goes around the thermostat in your cooling system to allow some coolant to flow whenever the engine is running. This prevents to much pressure to be built up in the system, allows for even cooling at start up and even gives you a slight amount of heat when you start the engine. Your heater core is often part of the bypass system in a car. When the engine's thermometer opens the flow of coolant in the car increases this cooling the engine. As the engine cools the thermostat closes slightly and increases the flow through the core and bypass hose.
Where is cooling system bleed valve located on 1999 alero v6?
The coolant air bleed valve is located on the top of the thermostat bypass pipe/heater pipe assembly. Close the valve once a continuous stream of coolant is expelled from the valve.
Where is the thermostat on a 1989 Lincoln Town Car?
Open the hood, and look to the left ride of the radiator and about a foot or so down; there is a wing nut that can be turned counter clockwise until the coolant starts to drain out. Place a pan to catch to old coolant and turn the wing nut to drain. Once the coolant is out, remove the radiator hose that connects to the thermostat housing, as well as the bypass valve hose. Once that is done, there is a black bar to the right of the distributor cap, remove the bolt on the outside of the rail and the smaller one that is across from it. Unscrew the two bolts holding the thermostat housing together and remove the housing to reveal the old thermostat and gasket. Replace thermostat and a new gasket with a coat of Permeate #2 on both sides of the gasket. Reattach housing with thermostat facing proper direction, snugly attach and tighten bolts back onto thermostat housing. Reattach the black bar that is next to the distributor cap. Reattach bypass valve hoses and radiator hose, remember to secure the clamps properly. Tighten the wing nut that allowed you to drain the coolant, and then pour in fresh coolant and water until its to the top of the radiator. Turn the car on and let run for a little while making sure to add the remaining coolant into the flood reservoir that is next to the windshield washer fluid.
