Heater Core ?'s

I'm no longer getting heat out of my heater fan and everything works, I checked my inlet hose to the core and it's warm but the outlet from the core is cold does this mean my heater core is clogged or do I have bigger issues here? Thanks in advance for the help

warm engine for ten minutes, open radiator carefully, use a rag, with engine still running, lower a cooking thermometer down in coolant, wait five minute, pull it back out, it should read around 170 degrees at least, 160 wold be acceptable, this test will save you the trouble of removing heater core unnessary plus you can flush heater core with it in truck, just take hoses loose and connect water hose and let it rip

Re: Heater Core ?'s

My '94 Sonoma Reads About 160-170ish
Lowsy Heat, But I Already Assumed It Was The Heater Core.
As It The Only Thing In The Coolant System That Hasn't Been Replaced In The 3yrs That I've Had It.
Last 2 Owners Didn't Do Jack (i Knew Both).
The Core Is Original

Yup, here's a dash shot of my old '88:

"Auxiliary instrumentation in my S10. Autometer 2 1/16" Phantom water temperature, oil pressure, transmission temperature and Sunpro 2 5/8" tach."

With regards to no heat issue, your heatercore is plugged up. If you are lucky, all you have to do is remove the lines and reverse flush them with a garden hose. Chances are you will probably need a new one if it is the original one. You can read my post here on how to replace it. HTH's

It's a "suicide knob" that I bought from JC Whitney a few years ago. If you have never driven with one, they rock for driving one handed. Especially when turning while you have your favorite beverage in your other hand . However, they are illegal to own in some places unless you have a permit (at least here in the states).
