Replaced Thermastat and Radiator, but car is still over heating

check the hoese what is the difference in the top and bottom hoes temp should be withen 10 degree s of each other when hot

You mean the car is running fine but just No Heat?
If so
-Sound like the heater hoses are plug. or the control valve is no function

-Check the heater control valve and flush the heater unit with water of garden hose from both directions.
Q: How do I know that is working or not?
A: Slide the heater control from Hot to cold or cold to hot and check it turn or not. (If not turn at all. The cable is broken or slip off)

Needless to say you have not found the right shop yet.
You need to know if the water pump is pushing the coolant thru the system, is the system full of coolant and no air pockets, and is there excessive pressure in the system.
Do the radiator hoses and heater hoses get hot when the engine warms up ?
Are you sure the system is full of coolant ?
Do the radiator hoses swell up when the engine gets hot ?

YOUR RADIATOR IS EMPTY!!!!!

I think that one still uses cables to control the blend doors and vent doors. Are you sure those are working and/or connected.

Also when you replaced the thermostat and heater core did you bleed the cooling system? With the engine cold remove the radiator cap and let engine idle up to operating temp while keeping the radiator topped off with coolant.

Are the hoses going to the heater core hot?

Beats itself?? I really dont know what that means. the cooling fan should come on when the a/c is on. when the engine is hot, the radiator should be hot. turn the a/c on and feel the air coming through, it should be HOT, if not, there is a coolant flow problem.

First make sure engine is cool.
-Put drain pan under car, coolant will run out.
-Remove the TOP radiator hose that runs to the metal thermastat housing. Coolant will now be running out, try and direct it to the drain pan below.
-Remove the thermastat housing, BEFORE removing the thermastat make sure you TAKE NOTE at how it is situated in the casting.
- Take the thermastat housing and run a wire brush on the flat spot were the old gasket material is.
-Both mating sides of the thermastat housing MUST BE PERFECTLY CLEAN. There can not be any old gasket material left.
-Insatll new thermastat.
-Put a very light amount of PERMATEX orange high temp. silicone on BOTH sides of the new gasket.
-Put a small amount on bolt threads also.
-Now install thermastat housing, and bolts.
-Tighten bolts down a little at a time, alternating between the two, unitl till they are tight.
-Install the radiator hose, and tighten hose clamp.
-Remove radiator cap, pour in coolant, until it sits just below the radiator cap neck. This may take a little time as the system has some air in it.
-Install the radiator cap. Make sure you radiator overflow tank is filled properly.
-Remove the drain pan, make SURE ALL the tools use used are secure, and out of the engine bay.
-Start engine, and place your heater control to 'HEAT"
-Let engine run until the top radiator hose is hot, which means you thermastat has opened.
-Keep watching the engine temp AT ALL TIMES, we wnat to make sure there is no air in the system.
-Inspect for any leaks. Now when the top radiator hose is hot make sure the hose clamp is tight.
Please let me know how it goes.

it could infact be blockage or something in the radiator... or look for significant leaks... i have had a radiator that got clogged for no reason... you can go on ebay and find a NEW radiator for a good 50 dollars

Be sure that the fan is moving enough air across the radiator and be sure the radiator is clear of any debris. If it is and you're sure the system is full of coolant, have the radiator rodded out or replaced. This is most likely the issue. Hope this helps, good luck!

The brand new water pumps are junk. I put a reman water pump on and it works great.
