It sounds like your thermostat is broken. The metal retaining tabs that hold the thermostat together can break over time. I would recommend pulling it out and checking it. When installing a thermostat there is an arrow on the edge. Make sure it points up. toward the top of the cylinder head.

Thermostat may not be working properly, hot coolant has to circulate via the heater core in order to get heat. Normally operation temperation should be 180 to 200 degrees.

I just bought a 2000 4x4 Dodge Durango. The temperature gauge reads properly at about half way, but the heat blows air that is not really hot even though I have the heat at maximum warm. What is the...


try feeling your heater hoses going from the engine to the heater core. they should be hot at operating temperature. If one is hotter than the other noticably it would indicate a restriction in the core most likely. A partially stuck thermostat could also cause loss of heat but you say the temp is normal. Start with checking hose temperature if they are both on the cool side compared to the radiator hose then further diagnostics are necessary. hope this helps. Keep in touch.

Hey Chevy Minivan heater dont work properly


Chevy made some weak intake gaskets on 3.1 and 3.4. My guess is that the intake gasket is weak and/or leaking and it is letting pressure out somewhere. At idle maybe the system pressure is to little to push hot coolant into the heater core.

How to replace thermostat on


Do this when cool. Take radiator cap off, start the engine, turn on heat (not defrost) and now top up coolant to about an inch or 2 from top of radiator, as level drops down, and let vehicle run until the radiator fan comes on, then off, about 3 times, and add coolant as needed while it's running. After that, put radiator cap back on tight & make sure return bottle is filled to proper level. Now try that & see how heat is, temperature gauge etc, and keep an eye on return bottle level for a while. Let me know how it is.

Heater only blows cold air but hoses are hot


Hi!
It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.
If persistent boil ups/over attention must made in the cylinder head
or gasket area, or possibly water pump?

The engine seems to overheat and the internal heater blows cold


The problem is your coolant level has gone too low check and top up when engine is cold, you will see the marks on the expansion bottle, if prob persists there may be an airlock in the heater radiator. keep an eye on coolant level or you will have cylinder head problems.
