I had the same problem with My 1990 F150 300 6cylinder 4x4.....I cahnged all the same things you did, finally I sprayed a can of Gumout through the throttle body and it worked and ran great. Now I add fuel injector cleaner to the gas and a regular clean with the gumout and the problem has'nt come back. Good Luck to you and hope it works!

SOURCE: 1995 ford windstar overheat after replacing the thermostat

Let your engine warm up with the rad. cap off and see if the coolant level drops. and make sure your overflow is full. It blows cold air because there is no water getting to the heater core. And it shows a normal(ish) temp because the water needs to be touching the temp. sensor. I really do think there is air in the system and there is not enough coolant but hard to tell from here. Also as with overheating any time make sure to check your oil and look for any coolant as the head gasket seldomly holds together if the motor overheats.

SOURCE: 1991 camaro overheating

There are two freeze out plugs at the rear of the block (V8) and many v6 engines. If coolant is coming from where you say, likely they have failed. Unfortunately, the only way to reach them is to remove engine or transmission, It's rare that they fail because they are "protected " by the bellhousing, but can still rot from the inside out. There is no sealer known to man that will fix this. It's a shame that you need to do all that work for a pair of $2.00 plugs, but that's what needs to happen.

SOURCE: 2002 malibu runs hot.

Sounds like you have a faulty head gasket or maybe a cracked head.This can cause overheating and the check engine light to come on.The code for the o2 sensor is probably caused by coolant getting into the exhaust system and coating the sensor.The coolant fan may work but it cannot remove enough heat from the rad to make the engine cool off.Try some engine coolant stop leak to see if it will help.This maybe only a temperary fix.Let me know if you need more.MOE

Heater blows cold air when the truck is idling or in stop and go traffice
a question to an answer: is your truck has any heat when you rev it 2000 rpm, or above?
have you check your coolant level? if level is low you have a small coolant leak, a water pump may be at fault, and causing air pockets in your heater core, check for leaks your self, dealer wont tell you if vehicle still under warranty.

My heater blows cold air when car is stopped. i have installed a new water pump and the radiator is full of water.
you still have air trapped in the cooling system. Get front of car as high up as you can on a hill. Cold engine - loosen radiator cap, fill with 50/50 antifreeze mix. Start engine and run until upper radiator hose is hot (thermostat open). Engine should burp air and maybe spill some coolant, that's ok. Once burped, tighten cap, shut off engine and let it cool down while keeping the reservoir full. It will **** coolant out of reservoir as it cools. Keep it full.

If still cold air, take to a shop that has evac/fill equipment; they will **** air out and repalce with coolant. About $80.

How to replace the water pump
Water Pump
REMOVAL & INSTALLATION
CAUTION
Never open, service or drain the radiator or
cooling system when hot; serious burns can occur from the steam and hot coolant.
Also, when draining engine coolant, keep in mind that cats and dogs are
attracted to ethylene glycol antifreeze and could drink any that is left in an
uncovered container or in puddles on the ground. This will prove fatal in
sufficient quantities. Always drain coolant into a sealable container. Coolant
should be reused unless it is contaminated or is several years old.

2S-ELC Engines

  1. Drain the cooling system.
  2. Remove the timing belt as described in this section.
  3. Remove the alternator adjusting bar.
  4. Disconnect the lower radiator hose from the water inlet housing.

Car overheats new radiator 2 t stats diffrent eng new water pump, had same problem with first motor cust cooked first motor filled cooling system with radicat plus overheats sitting in shop heats up real...
Okay sounds like you have a clog within the system, first of all, drain the whole cooling system, run clean water thought the top of the radiator, look to see when the water comes out nice clear, replace the lower hose if you have a petcock close that, refill the top of the radiator, until it is full, start the engine, with engine running turn your heater, let the car warm a little, then reopen the petcock or loosen the lower hose and let the water draw out a little until is pouring out nice and fast, then re-close the petcock and stop the engine.
try and get 40% of the water out, and replace it with 50/50 antifreeze fill to the right point of the cars specs.

2004 Chevy Impala no heat from defrost or heater
No heat is often a symptom of low coolant, usually followed by overheat. There are other controls that regulate heater, but right now, re-fill the cooling system with engine running and heater on high, then check for leaks (coolant you lost went somewhere...you need to determine where) Low coolant will damage your engine. Take care of that first, then if heater still does not work, then do diagnosis on that. (if you loose the engine heat won't matter, will it!)

Chevy 1500 Heater problem
It sound's like a problem with the water pump, thermostat, or drive-belt, drive-belt tensioner and pulley, check the tension on the drive-belt, if it has good tension check and or replace the thermostat, if your still having cold air coming out at low rpm's it could be a bad water pump. you can check the water pump by looking to see if there's coolant leaking from the weap hole, or listen for a squealing noise from the water pump when the vehicle is running, there's also a possibility of air in your cooling system which usually occur's when you have the coolant system opened up for repair's, if there is air in the system it could keep the coolant from flowing properly, only way to get it out is to bleed it out using the bleeder valve, im assuming the coolant level is at the proper level,
I hope this was helpful. Good luck.
