i think that my 97 type r has air in the coolant system and i can not find the beeld screw so if any one can send me a pictuer of it or tell me were it is that would be cool

 

It is located on the bottom of the radiator and is accessable from underneath the car(white plastic wing nut)

the motor is in a 93 si hatch back so would it be in the same place

 

how do i get the air out of the system

 

Run it with the rad cap off until the fans kick in a couple times. May have to rev it up a bit to ge the temp up. Just keep adding as it goes down.

What is REALLY handy and something I use at work is this:

how do you tell if all the air out of the system

 

Q: Why is it important to remove all air from the cooling system?

A: If air is trapped inside the engine block or cylinder head(s), it will cause an overheating condition. This could result in very costly engine repair or possibly engine replacement. A radiator or fill tank can look full but it does not mean that the engine block or cylinder head(s) are full.

Q: How does the air get trapped inside the engine?

A: Many newer model vehicle designs have lower hood lines and are more aerodynamic, which means that the engine is positioned higher than the radiator. While this promotes a more attractive, sleeker look, it creates a problem within the radiator. Basic physics tells us that water, which is part of the engine coolant, seeks a natural level. The coolant cannot be drawn into the engine efficiently because air exists between the upper portion of the engine block and cylinder head(s).


Q: How do you remove the air that is trapped in the upper portion of the engine?

A: You vacuum it out using the AirEvac (P/N 04700) from Mityvac“. This is a tool that creates negative pressure within the cooling system (a vacuum). By creating this vacuum, it removes the trapped air and refills your cooling system while still holding your system in a vacuum. All fluid will be drawn from the coolant container into the system until it is full. (Ensure you have enough coolant mixture before performing this task.) Once the system is filled the vacuum will no longer exist because the coolant now occupies the void. No Air! No problem!

Q: Air never hurt my old vehicle. How can it hurt my new one?

A: Radiators in the older vehicles were positioned higher than the engine. It used to be easy to just fill the radiator and run the vehicle until the thermostat opened and then top it off, put the radiator cap on and drive away. With newer vehicles, most manufacturers specify to purge the air out of the cooling system. If air gets trapped in the engine block or cylinder head(s) and it is run for any period of time it will cause "hot spots". This will damage head gaskets, the cylinder walls and the entire cooling system. Overheating and expensive repairs will be the end results

 

it is not working i have ran it with the cap off three time and it dose not fix the problem with the retrun line it keeps closeing shut when it is cooling off with the motor off

 

What keeps closing shut? I'm not quite understand what you are talking about

There is also the option of jacking up the front end ofthe car and running it. That way the air has a better chance to get to the rad and out.

 

the coolant retrun line when it cools down it dose that
