Chevrolet S10 Heater Issue Sign In

Hey, I own a 1994 Chevrolet S10 Pickup with a 2.2L engine. The mileage is 122,5XX. I am currently having trouble with the heater as it blows lukewarm air in heater and defroster mode. After checking under the hood, I noticed two pipes without a hose connected to either one in the back. Does anyone know which specific hoses I need? Also, could anyone tell me if there's more that could be causing the heater issue? Thanks in advance for any help!

Heater cores don't usually get bypassed for no reason, usually it's because they are leaking...

You can see the heater hose if front of the heater core pipes in your picture. You can hook the 2 hoses back up, but more than likely the heater core is leaking....

It's pretty hard to have any heat when the heater isn't hooked up..........

Re: Chevrolet S10 Heater Issue Sign In

Quite sad that I come to a forum searching for a little help and answers from others who are more car savvy, yet I get mocked for my lack of mechanical knowledge. Sidom, if the case is that the heater core is leaking, I shouldn't have too much of a trouble of finding one and replacing it. My question now is, what are the names of the two hoses I need and do I need to buy any other accessory for the heater core?

Pls don't take their replies in the wrong light.... Just a little bit of light natured humor, nothing directed at you.
I can be the worst offender at times but the only way I got out of my cage today was by promising to say in line...Wink

Doing the heater core is actually a pretty big job, which involves a lot of dash work. Depending on you level of expertise it may or may not be in your range...

If you look at that heater hose going in frt of the heater core, that is one of the hoses that goes on to the heater core. They just took that hose and put it on the fitting for the other hose, kinda of a loop to take the core out of the picture. You may need to go to the parts store to get another piece of heater hose to go from the other heater core fitting to the engine....

I would hook the core back up and see what you got....More than likely it's leaking but you will never know until you hook it back up and run it......

Do that & let us know what you have......My database is down right now but I'm fairly certain the dash needs to come out on this one to replace the core....

You know, it really is something that makes us giggle. That heater core is an 8 hour job for a professional. Excuse me,but if you can't identify the heater hoses, you have no business even considering that repair.

Re: Chevrolet S10 Heater Issue Sign In

I understand. I just want to learn more on how to deal with cars from others that know what they're doing and in no means want to bypass anything or fry my engine. The previous owner rigged this thing up pretty badly so I need to go back and fix it one piece at a time. I will go let you know once I get the hose hooked up what's up.

The hoses are off for a reason. I'm sure the heater core is leaking into the truck and that's why it was bypassed so you need a new heater core and that is a major job on the truck.
