Check the L shaped hose at the back of the TB.

 

Good luck,

also check the hose that goes between the thermostat and the top of the block. you should see it just behind the power steering pump. when this leaks, it usually drips off the back of the head or the #3 spark plug

I've checked the hoses and none are leaking. I've seen the coolant weeping from the seam below the TB and above intake........

 

Is there a gasket that goes between the two?

 

If so, is it the horseshoe/toiletbowl looking o-ring?????????

 

thanks.....

can you see exactly where it is? If not, you might look at the bypass (I think that's what it's called) hose that goes from the top of the water pump to a pipe that runs along the top of the block to the heater hose. I had this leaking in my 87 hatch, and it would dump a 1/3 of a gallon every time I'd shut it off. The hose is under the a/c compressor, but if you have a pressure tester and skinny arms, you can take off the fan guard and try to feel it.

 

As far as a gasket, I don't know. However, I don't see why it would leak there, not really a need for coolant in the tb, unless it is a pre-heater, but still. But, if you see the leak coming from there, I can't say it is not possible.

 

Good luck on getting that leak fixed.

yes there is a gasket that goes there its u shaped and coolent runs thro it to cool the intake mani take it apart its easy and put in a new gasket it happend to me awhile back

thanks for all the help......

 

I replaced the U shaped oring and that solved the leaking from between the tb and intake....

 

Now it appears the thermostat housing gasket is going....leaking there.....

 

more fun???????

 

thanks

might as well do the little hose, too, or it will go. Your subaru will like yummy new hoses

Just to clarify......

 

You say 88 Hatch. If that were acurate, youd have a carb, not F.I with a throttle body.

 

Since you describe the "u shaped" gasket, I assume this car is F.I., which means it is probably a 3-door coupe. Not a true "hatchback"

 

You have a 3-door coupe, SPFI, EA82 engine.

 

an 88 "hatch" would be the older, early 80's bodty, and have an EA71 or EA81, with a carb.

Does a small coolant leak from the intake manifold considered as an emergency situation? I can't fix it now since my money is sort of on a leaky hose this week..

As long as you do not lose so much coolant you overheat. Keep the coolant up and you will get by. You will know the coolant is too low when the heater goes cold when driving, and you can add some before it overheats.

 

If the leak is profuse, you can just use water, and then replace with new coolant once you fix the leak
