I have a 2001 dakota that is overheating. put in new thermostat, didnt help. put in new water pump, still overheating. finally replaced the radiator. still is overheating. what else can I do to fix it

Sometimes when you open cooling system, air gets in, it can cause problems with temp gage.
How hot does it get in degrees F? Is the coolant boiling over? Are you losing coolant? Use a non-contact infra red temp gun to take engine temp, At least we will have a degrees F reading. Most temp gages say hi or lo, cold or hot. I don't know about yours?
Can you check for combustion gases in the coolant?

I think it's the hot water valve also, at least check it by feeling the hoses that go from the heater to the engine,
If hoses are hot, then its ok. it's a sign that hot water is circulating
and you should go ahead and drain the coolant and see if it's dirty, or has stop leak, and refill the radiator with fresh coolant, be sure to pour in as slow as you can. be patient
now at least you changed your coolant, and no air pockets trapped in the system. go from there. if it's the hot water valve you can look it up on you tube.

My 98 ford f150 overheats constantly. I have changed the thermostat, fan, fan clutch, gave it a flush and still overheating. A mechanic checked it and said the water pump is good cause water is...

does the heater work good, like real HOT when the truck is HOT? if not, flush the heater core with a water hose, both directions. Now when the truck is HOT open the hood and feel the air coming thorough the radiator, it should be HOT. if its not, the radiator may be plugged. If the mechanic has a Temp Gun, have him check the radiator temp, it should be uniformly HOT if you find cold spots (like if the radiator is 200f and there are places that are 150f) the radiator is plugged and "flushing" will do nothing.

I have a 1996 monte carlo it runs hot on the gage has no heat but never smells hot or anything. Gage will peg out and kick hot light on then come ack down and keeps doing that. Any solutions?

No heat sounds like the heater core isn't circulating. Dropping down, sounds like the thermostat is sticking for a while than working. That can be checked by feeling the hose when the temp is up. If it is hard at the hose where the flow goes in; I would consider changing the thermostat. It can be a bad circulation problem killing the themostat though.

Im not getting full heat on heater and temp gage stays at lowest level, why?

Thermostat could be stuck open, I've seen them break and the coolant just keeps circulating

Why is the heat blowing cold air but at a really high idle it blow hot air for little period of time.the temp of the engine is 195degrees. all the fan controls and the temp control is in the hot position

you could have a couple things going on. possible low coolant? most likely cause as i assume you have checked coolant level would be heater core restricted. to fix this you remove heater hoses and back flush heater core with water. if this does not do it you may have a water pump not circulating at idle but this usually comes with vehicle running hot at idle.

98 dodge dakota slt 318. no heat, low operating temp

First thing first, turn off the engine wait for 15 - 20 mints, open the radiator cap and fill it up to the top then start the engine and see if it needs more water adn add as needed, then wait till you ca see the water circulating in the radiator now instead of corculating if it starts boiling out shut the engine replace the thermostat and do the whole thing again.

unless there is water in the engine the gauge will not be able to show the actual temp of the engine, so always malke sure you have water / antifreeze

Follow these steps:

Check coolant level, then start engine until it is warm and the thermostat opens. You will tell when it does when the needle on your temp gauge goes cold when it reaches around 180-200* and then goes back up. Now turn on your heater full blast and go to the engine compartment. You will see a heater valve located on the passenger side, next to the washer reservoir. It is a black thing with 4 heater hoses connected to it. Feel the hoses. When everything is working correctly it should be like this:

Hose going to waterpump will be hot
Hose going to (I think the thermostat housing) will be hot
2 Hoses going to heater core (mounted behind firewall) will be hot

1. If only 1 heater core hose is hot, heater core is clogged--
UNCLOG: remove 2 hoses going to heater core when engine is cool, hook water hose end to one of the sides and flush out gunk from heater core. Reconnect hose and you should be good.

2. If neither hose core hose is hot, heater control valve is bad or vacuum is bad--
Test Vacuum: remove vacuum line from heater control valve, you should feel the vacuum **** on it when pressed to your cheek and the heater control valve actuator should move when you unhook the vacuum line. If you have a good vacuum, it's probable the valve available at autozone part # 5941 for around $21.

To get heat while you wait to replace part, unhook silver arm on heater control valve that is hooked to the plunger. This will give you heat all of the time, but it is controlled by the bottom hot/cold switch on your heater control unit so you won't get hot in the cab. It will just circulate heat through the core.
