Pointy side up. You have a groove in your intake and that is for the thermostat to rest in and then the tope of your thermostat flange should be just about flush with the intake top. That’s there the gasket or o-ring rests.
Which way should my thermostat face?
The shorter end (Arrow B) of the thermostat always points toward the radiator hose, and away from the engine. Therefore, the deep end (Arrow C) of the thermostat always gets installed going towards, or into, the engine.
How do you put an O ring on a thermostat?
Put in Thermostat then Oring then housing on top. Oring is to seal between housing and thermostat not thermostat and engine block.
Do you put gasket sealer on thermostat housing?
Since the thermostat in your car has a regular gasket, you can use RTV or not, at your pleasure. If you’ve had seepage issues in the past, it’s almost a given you’d use it. Even if you haven’t, it’s not going to hurt anything to use it now. If you do use it, only put a thin coat on it, covering both sides evenly.
What happens if you put the thermostat in backwards?
If you installed the thermostat backwards, it would probably not open up enough to allow coolant to flow, and the temp gauge would shoot up into the far right range, the engine would overheat, etc.
Which way does coolant flow through a thermostat?
The hose on the right (passenger) side comes from the top of the head, HOT water. The left side returns cooled water from the radiator to the thermostat to the water pump and then into the engine block.
What does the jiggle pin on a thermostat do?
The thermostat jiggle pin is a pin that is located in the small hole in the plate valve of the thermostat and which should always be in 12 o’clock position during installation. It helps bleed the cooling system of trapped air by allowing air to pass into the radiator, after which it can be released from the system.
Where does the o-ring go on a thermostat?
I figured it out. Thermostat goes in first, then o-ring seal. The end of the thermostat housing is tapered to make the seal with the o-ring.
Does a thermostat need an O ring?
Member. no there is no need for an o-ring it will not move around once the housing is bolted to the intake. The gasket/silicone is all that is needed.
What is the thermostat housing?
In many internal combustion engines the Thermostat Housing acts as the coolant outlet, it is normally located on the engine block or cylinder head.As the name implies, this engine component houses the thermostat which regulates the coolant flow.
Do you put gasket sealer on both sides?
Many mechanics will use an RTV gasket maker to hold a conventional or cut gasket in place during assembly. Some mechanics will even use the RTV gasket maker as a dressing, coating both sides of the gasket.
Do you put silicone on both sides of a gasket?
NEVER use silicone on both sides of the gasket, the gasket will slip and slide all over the place instead of staying put and clamping down. Another substitute for the high tack is Copper Coat (in the copper spray can).
Should I use gasket sealer with a gasket?
A general rule, if you are using gasket sealant, you don’t need a lot!Automotive applications commonly use gasket sealant alongside solid gaskets, as they are repairing older parts. Gasket sealant can be used to make cheaper gasket materials more robust, increasing adhesion and chemical/water resistance.
Does gasket go on top of thermostat?
Gasket goes on after the thermostat.
Where does the thermostat go in a car?
In most cars the thermostat is placed under a housing near the water pump on the cylinder head ; the housing is connected directly to the top radiator hose . In a few cars the thermostat is housed near the bottom hose. Test the thermostat quickly by starting the engine from cold.
Can you install a thermostat wrong?
Potential consequences of improper installation could include: Electric shock. Blowing a circuit breaker. Damaging the thermostat unit, the electrical system or even the AC/furnace unit itself.
Why is my car overheating with a new thermostat?
You could be having a problem with your radiator being clogged up. This will cause the flow of the coolant in the system to be restricted, causing the truck to overheat. A clog in the heater core could also cause this problem. However, if the car is still getting heat, the heater core can easily be ruled out.
Why do cars have two thermostats?
Their purpose is more for aerodynamics than engine cooling. The dual thermostat system was designed to accomplish the same temperature control under different load conditions. Instead of manipulation of the air side of the radiator, the coolant flow to the radiator is varied.
Does coolant enter top or bottom of radiator?
In a cars cooling system, the heated coolant (water) enters the radiator at the top and moves through the radiator where it cools down as it falls to the bottom of the radiator.
Where does coolant go when thermostat is closed?
The thermostat is located between the engine and the radiator. This little temperature-sensitive spring valve stays closed during engine warm-up. When the thermostat is closed, it prevents coolant from leaving the engine and circulating through the radiator until the correct running temperature is reached.
Which way does the jiggle valve go on a thermostat?
The FSM says the jiggle valve must be pointed downward at the 6 o’clock position. Some people with the Haynes manual for their trucks says it’s supposed to be placed at the 12 o’clock position.
