Heater heat

My 68 has a control valve on one of the heater core hoses since it is an AC car? Does yours?

I have used CLR with excellent results in the heater core to remove deposits. I remove the hoses from the engine and use compressed air set at about 15 pounds to remove the antifreeze and water. Then I pour the CLR in the hose that has the connection the highest on the heater core. I let it stay in for about an hour and then flush the heater core out really well from both directions several times.

.

its a non a/c car ...hmmm that clr is a good idea ...never thought of that

Might not be a plugged up core, but just the airflow through the core being blocked by debris or a vent door not working.
A quick check is to see if both hoses under the hood are close at all to the same temp, or if one is hot and the other cold.

One hose hot and the other cold is a plugged up core.
Both hot, but no heat is blocked airflow.

the heater does get hot but it just lacks that extra ooooomph im looking for

What temperature is your thermostat, 160, 180, 195???

Try running a 195° thermostat for winter..

Maybe eat a few more orders of Sonic Tater Tots to put a few pounds on also....

no idea what thermostat ....what ever comes stock ...how do you check?

Cardboard in front of the radiator.......cheap & effective

brrrrrr I hate cold

funny you say that because when it really gets cold here in January I do see trucks and school buses with cardboard blocking the grille ....or between the grille and radiator. I have seen that.

If both hoses are hot, make sure the plenum doors are actually moving fully when the selector on the dash is changed. I've had pencils, candy wrappers ect. keep the doors from moving.

I ralley dash swapped this car but when I took out the original dash ...your right, a lot of stuff that didn't belong came out and the heater controls needed greasing and the resistance broke off some of those little white plastic stud thingys ......but I was sure I corrected all that in dash

:DTake out the back seat and install a wood stove. Store firewood in trunk for traction in snow. Sorry but I had too!

I like it!!! that is a great idea. LOL ...I bet there is a custom van out there somewhere that does have a stove in it. LOL

You know something I thought of was the factory vent tubing. The flimsey plastic stuff. Maybe figure out a way to insulate that to keep it from losing heat? Just and idea.

yea the factory ventilation system has always seemed weak to me ....I have no idea why they never put more vent outlets
