Help! Let me preface first by saying I know next to nothing about cars, but here goes...
I have a 1992 Integra with about 243,000 miles. My brothers gave me a tune up in May and everything has been going great. They replaced the temperature sensor and the thermostat because the temperature gauge would go immediately all the way to hot when the car had only been on for a minute. It has been running great all summer, even in the heat of the California Central Valley. The last couple of days, I made a few quick local errands and in doing so, I noticed that my heat gauge creeping beyond the half way point up to the dreaded "H". When I returned home and opened the hood, I noticed a significant leak at the back of the fuel injector - from what I could tell it's a 1 of two hoses that attach at the smaller projection on the back of the fuel injector. 1 looks like it attaches to the larger section of the fuel system and the other looks like it drops down beneath the system and where it goes, I can't say. So has anyone had a problem like this before? Could it be something other than coolant? Should coolant even be running to the fuel injectors or is my engine screwed up and everything is going where it shouldn't go? Help!!! Thanks for sharing your advice, experience etc. I really don't want to give up driving this car... I love it. Plus I'm out of work and really can't afford to get anything else.

If you could take a pic and post it up it would help us alot. And theres no way coolant can get into your Fuel lines. If there is theres something really wrong.

 

I'll do that now. I have a Haynes manual and I'm reading something about a throttle body that coolant goes to. But I'll take a pic and post it.

 

It sounds like the exact same problem I had - a leak where a coolant hose goes into the throttle body. There are several in this area: in/out lines for the IACV, in/out lines for the FITV, and the larger throttle body line.

 

Okay, I've got pictures...

It was definitely from one of those two, and I really think it was the first.

 

That's your IACV (Idle Air Control Valve), not the fuel injection. It helps your engine idle, and coolant runs through it. One of those hoses in coolant IN, the other is coolant OUT. I'm pretty sure about this, but from the second picture it's unclear to me whether you're pointing to both of those hoses.

Let the car cool down, then try removing one hose at a time. They will be difficult to pull off unless they were removed recently (they tend to stick to the metal). Inspect for cracks/wear, then get to the auto parts store and find a replacement. When I removed my IACV, taking off the hoses was the hardest part

 

Thanks so much for your help. In the pictures it's hard to see the second hose as it's behind the first in that view, but that was the best I could do in getting my camera down there. Do you know where the second hose runs back to? My brother in law is going to help my with this tonight, and I'm trying to gather as much info as possible. Thanks again! I'm sure it will be tough as they are the originals and the car is almost 18 years old!

 

Yeah 18 years and still running strong! honda ftw. I'm going to upload a picture for you, one sec.

 

Remove your air intake at the throttle body for easier access. Hose 2 might give you some trouble, hope the picture helps.

 

Thanks so much for your help!!!! I'll let you know how it goes. This might get shifted to this weekend...

 

So I tackled changing the hoses this morning as well as cleaning the IACV under the guidance of my b-i-l. It went really smoothly and I feel really great that I actually did the work - got under the car and greasy. My sister's are pretty impressed! But I couldn't have done this without your help - so many, many thanks!

 

So you found the leak and fixed it up? glad to know it went well. keep up the good work and keep that DA running!
