Question about 1996 Chevrolet C1500

1 Answer

How hard is it to change a Heater Core on a 1996 Chevy Silverado. My heater is worthless. I've changed the Thermostat with a Stat 195 degree and flushed out the heater core. Still no heat! I've also replaced the Radiator with a Brand New Heavy Duty One and nothing.

If you flushed out the core and have good flow through it, likely the blend door inside the heater box is not opening. Check the vacuum motors on the box and make sure they are moving as they should.
How difficult the job of removing the core is depends upon your skill level but no one I know likes doing one. Get a chiltons or haynes manual and review the process before attempting the job...if it sounds difficult, don't do it (keep the manual though it's helpful for other stuff)

I have a 97 chevy k1500 i have changed everthing dealing with cooling system a/c workes great my heater dosent all accuaiters arev working temp gauge shows 165' plz help

If your saying 165 degrees F, that isn't right, in my opinion. With a 5.7L engine and 195 degree thermostat, I want to see over 200 degrees F on a fully warmed -up engine.
Are the heater hoses hot?

Car heaters not very hot

try changing the thermostat and make sure all the air is bled out of the system this should help your heat problem.before changing the stat with the motor at operating temperature grab the heater hoses to see if they are the same temperature or not.if they are the same then change the stat.if not the same temp then the heater core may be plugged or partially plugged and will have to be changed.still change the stat as they do get tired and won`t work properly.

92 chevy 1500 silverado Changed thermostat,heater core, core hose not hot. No heat

It sounds like your heater core is stopped up. try flushing it out, you can use a water hose. and if you cant get it to clean out then you will need to change the heater core.

4.3 liter won't gain temp, why?


The chevy blazers are known fior heater core issues clogged going bad etc... The reason im saying this is because the only reason i could see you having a problem with the temp not getting hot enough is because then your heat in your car isnt getting hot or its taking super long to get luke warm, is that correct? If so 9 times out of 10 its a bad heater core...

Have your heater core flushed, install new thermostat and coolant. It has to be 195 degree thermostat to work with your computer controls on your engine. hope this helps. Phil

Cooling & heating?

as a test, restrict a good portion of front of radiator with cardboard. is the engine running at 195 degrees? if engine temp is good, verify that both heater hoses going to heater core are hot. maybe heater control valve.
