I just finished up w/ water pump - thermostat replacement. I have never done before on this truck. I am feeling my way through. So my question is ... I added 1 gal. dexcool, then started adding gal. water. going very slow, adding through rad cap opening. after 20 min no more water was fitting. Started for 30 seconds thinking will pull into block. afterword the the overflow tank has coolant already. I'm less than 8 quarts. Was told 18. what gives? what should my next step be? thanks you guys are awesome.

I can feel your frustration. It sounds like you've done all the logical stuff already. The "donut hole" in your process would seem to be not changing the water pump. The water pump as you might imagine, is responsible for circulating (pumping) the relatively cool water in the radiator into the running engine that contains the hot water. Hoses connect the two together. A thermostat is between the radiator and the engine. Once the water in the running engine gets to a certain temperature, the thermostat opens allowing the water pump to send cool water into the engine and hot water out to the radiator to be cooled. The heater core is usually on the passenger side firewall area.
It sounds like the water pump is the only thing left to change - if it isn't working - it can't circulate the water - and will result in overheating. Lastly, a clogged heater core shouldn't cause the engine to overheat - in fact, if the engine begins to overheat, you should turn the heat to HIGH fan and HIGH temperature to help remove some of the heat in the coolant.
Check the cooling fans for correct operation. Have a pressure test done on the cooling system. Have a compression test done to check for head gasket or cracks. Check the condition of the cooling fins on the radiator and if they flake off then replace the radiator. Have a flow test done on the radiator to check for blocked cores.
Fix the radiator cooling problems. You will damage the engine if you keep running the car in an overheated condition.
1. Replace the thermostat in the cooling system 2. Replace the water pump 3. Flush the cooling system thoroughly and re-fill with the correct coolant. Bleed any air out of the system otherwise you will have problems with air blockages and thus poor coolant flow.
You probably do not know how to do any of this so take it to a reputable workshop or cooling specialist to have it done.
Get jeep up to operating temp Turn on heater to max heat Hood feel 2 heater core hoses goint into upper passenger side of engine compartment firewall. They should feel too hot to hold If it's not hot, could be 6 things 1. heater control valve is bad 2. Vacuum to heater control valve is bad 3. clogged heater core. 4. Bad thermostat 5. Bad waterpump 6. Needs more coolant (check when system is cold)
Do these things:
1. Disconnect vacuum line from control valve and feel under valve to manually move valve to open position. This should let hot water flow through core. If you now have heat inside, replace the heater control valve. Or you can disconnect the plunger on the heater control that is hooked on to the silver bar on the bottom of it. With it disconnected you can manually move it to the open position. It will always remain on.
2. When system is cold, disconnect both heater hoses going to heater core. hook up a water hose to one side of heater core and flush out any gunk. When you get done, the water should run clear. If you see lots of gunk come out, that was probably the problem. Replacement is like $20-30
3. When system is hot and engine running, squeeze the upper radiator hose (using gloves) when you release it you should feel a surge of water. Proves your water pump is working. If no surge, check thermostat. If thermostat checks good, look at the weep holes at the bottom of the water pump for traces of antifreeze. If you see a trace or stream of coolant, indicates bad pump.
4. As far as testing the thermostat, watch as your engine heats up on the gauge. when it gets to a certain point you will see the temperature rise, then lower, then rise again. This means your thermostat opened properly, cooling the system temporarily, then heated it back up. Replacement is around $5
hello anthony, several things could be causing your cutlass to overheat, The overall condition of your cooling system must be properly maintained for optimum cooling. The thermostat has to open fully at the correct temp. to allow coolant to be circulated through the block. Radiator fins, inside and must be clean and not restricted. The water pump and the fan clutch need to be fully operational. A clean mixture of 50/50 coolant to water filled to capacity is important. All cooling system hose in good shape and not kinked or restricted. Fan belts properly adjusted and not slipping---All this plays a part in keeping your engine running cool....If you haven't serviced your cooling system, i suggest you do so and replace the thermostat. I hope this information helps, good luck with your Cutlass.
I am not aying that this is what I think it is but I found this on your year BMW
Some BMW, Volkswagen and Audi cars have a common problem that the water pump
impeller becomes dislodged from the input shaft of the water pump
leaving the water pump looking ok from the outside, but failed on the
inside. If your car experiences this problem it will over heat rapidly
much like a thermostat failure. For exact specific repair procedures for
this repair visit our online repair manual page.
Failed BMW, VW, Audi Water Pump
Check Water Pump Operation
- To troubleshoot this problem first drain about a half a gallon out of
the cooling system, next remove the thermostat from the engine. With
the thermostat out start the engine (stand back) coolant should be
forced out of the thermostat port, if not the impeller has dislodged
itself from the water pump input shaft and needs to be replaced. To
replace the water pump finish draining the remainder of engine coolant,
remove the serpentine belt and coolant hoses. Next remove the water pump
mounting bolts and remove the water pump. Clean gasket surfaces and
reinstall new water pump and reassemble. Refill with coolant and recheck
system, top off engine coolant after it has re-cooled.
It sounds like you have an air pocket in your system. By the RH strut tower take the heater hose loose from the metal line and fill the cooling system when coolant starts coming out reconnect the hose. If that doesn't work jack the car up where the over flow tank is the highest point and fill the cooling system.
yes and also have your thermostat changed. but heres a way you can check before you buy these things: #1 car must be cool #2 let car warm up with hood open #3 find upper radiator hose and put hand around it...you should feel any water running through it! #4 after car warms to normal op temp, put hand around hose again and give it a squeeze...it should feel Hot and you should be able to detect a slight water back pressure..this will mean that both your pump and thermostat are working correctly. Also it is imperative that you read my tips and tricks on Dex-cool antifreeze, please, you could save thousands of $$$.
First, make sure engine is warmed up, then feel the top of the radiator hose, is it hot ?, if not then you may have a bad thermostat, replace with a 195 dgree, or you could have a bad head gasket.
Let me know what you find.
