Sketch diagram of the valve in the HIC - Hot Idle Compensator

Post by Dumindu » Mon Aug 07, 2017 9:42 am

In my carburetor (1987 Toyota Tercel DX Wagon RHD 1452cc 2bl manual driven car with Aisan Two Barrel carburetor), the HIC valve haven't been working for long time. Air intake to the HIC chamber was covered with a plug (previous user), but the components were there in a odd arrangement.

Following is the HIC chamer.

These are the components.

Can someone give me a diagram of the arrangement of these components?

Is there any lost component?

that should be in the factory service manual. the one used for North American is available for free down load from this site. I am not sure how much is different on your model, but the HIC may be the same, so it is worth a look at it.

@Petros There isn't any manual for the 1987 Tercel. There is a one for 1985 Tercel. But the stuff is quite different. Also no HIC valve in it. I found an online maual at here

But it doesn't have anything about HIC.

yes, unfortunately all of your fuel system is different. The carbs from ;83-87 in north American are all almost identical, so the '85 manual would be okay if it covered your export model.

there is nothing in our carbs in North America that looks like that. You will need to find one for your export model, or just have to figure it out without the manual. Perhaps you can locate another Tercel in your city and with the owners permission, compare it with yours. you might find something in common with a fellow Tercel4wd owner in your city. the '83-86 2wd sedan should have the same carb as well.
