I have a coolant leak that seems to be getting worse. It has been losing some here for the past month and I thought maybe the headgasket was going. Pulling in my apt. today it was starting to over heat. I got to looking around down below and found coolant dripping down the bellhousing. There seems to be 2 lines that look like they run to the carb(?) or right under it, anyways they are SOAKED. Are these coolant lines of some sort? Behind the motor? Specs are in sig, 22r. When starting in the cold mornings the truck idles high and then starts to chug chug chug. Almost like it is going to kill itself but it won't die, and you can tap the gas 2-3 times and it will go away and not chug any more. Related? Tried to get a few pics, bear with me and thanks. Pics make it even harder to see than it is. It is behind/below carb, 2 lines together. Rubber hoses. Smaller than coolant hoses that are in front.






Somewhere near those arrows, not the line with the red "X" on it, below that. Also not the yellow line.


Diff is marked, still can't really see anything. It's right in middle of back of motor, goes from one side to the other. And then runs into what looks like the bottom of the carb?...

 

Any help anyone?

 

General thoughts:
Have you cleaned the area with a degreaser to help track the coolant drip back to origin.
A mechanics extendable mirror and a good flashlight may help you see in the nooks a crannies.
Are the hose clamps on the heater hoses and other coolant lines in position and tight?

To my old eyes, the pics are blurry and make identification difficult.

 

Pics are blurry to my young, albeit corrected eyes. Lol. I'll try the degreaser thing tomorrow. I also remember seeing something from the Wabbit about putting foot powder on an area and tracking it. Problem is I also have at least one oil leak so I don't want to mix myself up. I don't even know where the heater hoses are to be honest? New radiator, upper and lower hose, and thermostat within the last month. Upper and lower are DEF good.

 

Use the FSM link in my signature and find one that is similar to your rig.....it will help a lot.

 

Would I be better off to use the one up til 1985 for Pickups and 4Runners? 22R is my motor. Or the 84-89 4Runner one?

 

I dunno.....take a look at both, I guess. It's too bad there is not one that is more exact to your needs on that site.
