I have an '89 pickup with the 22re. It's dripping anitfreeze from a junction on the passenger side of the block, just below the valve cover just past center towards the firewall. A pipe goes from that junction back towards the firewall. There are two 10mm bolts attaching this pipe at the junction. I tightened both bolts but it's still dripping. Is there a gasket there that I can replace?

 

i know on my 3rd gen 4runner there is a IAC valve with a coolant line going through it. I believe it's there to keep the intake warm and to prevent icing from colder climates. I would suggest to take it out and maybe put some type of make a gasket material and retighten?

 

The coolant is what operates the IAC, (AAV) which is the cold idle-up valve. Remove the coolant line and the idle won't drop when the motor reaches operating temp. Better to check the valve and if leaking, replace it. There may be a seal that can be replaced, short of the whole valve.

 

yep there is a gasket for that tube. They are real cheap.

 

I noticed there is a wire going to the top of this junction. Will try to find a gasket today. Thanks for the advice.

 

That is the coolant line to the heater and may tee in for the IAV. The dash temperature gauge's sender is on top of that. If you can't find a gasket, you may be able to RTV it.

 

had the same problem doing the Hg on mine. make sure you clean the pipe real good and there's an o-ring that fits in a small recess. I think i used right stuff on mine not the gasket. On my friends the p.o. used j.b. weld on the hole dam thing!

 

I tried making my own gasket. Took 2 tries, but I made one that didn't leak. I also had to remove that part later, and used RTV. I would recommend RTV, as that seemed to work the best. Only reason I recommend RTV is because it's not a pain in the arse to scrape off and replace if you need to remove that part in the future.

 

nice. yeah I hate that freaking pipe. its the heater core line if its the one I am thinking of. underside of the intake?
first time I messed with a 22re I was told it was egr. so I blocked it off. yeah I just ran with it and put no sence for what one was saying.

 

I just spent my weekend replacing the head gasket on my 86 4runner and got EVERYTHING back together, put in the coolant and that pipe leaked like a sive...Now I have to take off the EFI to get to it. I looked for a gasket in the engnbldr kit but I didnt see what I thought was the correct gasket and figured there was not one so I installed it without a gasket....WRONG! I am guess one of the small o-rings is for that thing? Frustrated...
