Heater in trackicks
« on: January 28, 2004, 04:30:35 AM »
How well do they work, I'm getting the feeling mine's got issues.  I can have it running full blast when it's 40 or 50 degrees here in AZ and it's still not all that warm from the vents.  (i.e. I can leave it on full hot on the dash vents blowing at my face and it's not very warm.  Any other car that would drive me insane in about 2 seconds flat).

Is it just me or are they all that bad, can't imagine they are or I'd see more of you guys in cold areas complaining I would think.

If it's just mine, anyone else had this happen and if so what fixed it since tearing into stuff under the dash is pretty much equivalent to my personal hell and I'd like to minimize any under dash work needed.

No their not.  my friends tracker with a soft top will run you out of there at -10.
Make sure your core is not plugged and verify the air temp door is functioning.

I'm somewhat warm on my 90 mi commute |removethispart|@ -31F, so at 40 - 50F you should have tons of heat pouring out of the dash.  Hell I don't even have the heat on at 32F ;)

My 89 has issues too. It is very weak. I have heard that they are proned to getting leaves and dirt in them and getting clogged up. I still havent taken apart my ducts to see how bad it is. I just bundle up when it gets cold.

My heater is strong, too. There must be something wrong with yours, Z3bra. Is the air flow strong but not warm? Is there a way to check whether the heater control valve is opening all the way?

Yeah airflow seems to be about the same as when the air door is on cold.  My A/C blows fine and now that I think about it it seems like it used to blow warm enough I'd have to turn it down.  I'll check for a plugged up core or leaves or something then it sounds like.  

I doubt it's the core itself, I actually use distilled water and 70/30 water/antifreeze so with the aluminum block not adding to the sediment it shouldn't get too crappy in there.  Probably the air diverter door sticking or something is what I'm guessing it is first off.  

I'll have to look in the  service book when I get home but does anybody know offhand if there's a valve for the water flow to/from the heater core or is it always going through the core and just the flap/door for the air that controls the heat?

When the truck is heated up, pop the hood and feel the heater hoses.  Are they hot?

If your coolent is clean and the doors seem to be working fine you might try a new thermostat.  If it's stuck open the engine will never heat up.

Yeah that's a good point too, definitely worth a look.  Also on a related note never run without a thermostat, it creates the same sort of problems with not heating up, but because the coolant flows too fast through the engine and head and doesn't remove enough heat from them it's a good way to end up with a cracked head or even a cracked block.

I compare the heater in my friends rig to "hell" with the devil himself stoking the fire. I mean that little S.O.B. is just hot, hot enough to fry chicken.

Mine's good, but it takes a bit to get percolating.  ONce warm, its like a sauna in there.

I run the 160* Thermostat, heater is warm
but not hot, with the stock 180* it was much
warmer, I agree, check thermostat, also do
you have a Temp guage ?? it should run in
the center, at least mine did with the 180*.

Water is always flowing through the core, temp
is door/flap controlled.

The blower switch has a problem with comming
un-soldered, I've fixed mine twice, seems I did
it good last time, I waited until I only had high
then took the switch out and re-soldered it.

My temp guage is usually about 1/4 of the way up (when it's not bouncing, I have a lose connection/broken wire on it I need to chase down so it sometimes flakes a little bit while driving)

It's probably the conection at the sensor,
the sensor is close to the thermostat housing,
has a rubber boot on it, the last one I had
to replace because the terminal pulled out
of the sensor.

1/4 way up is where mine runs at, (160*) so
that's why its not hot, I came home tonight
and it's only like 45* outside, maybe 50*
and the heater was just barely able to keep
me warm without a coat on.
