Radiator on 1993 Cadillac Sedan Deville boils after 2 miles
I had this problem all last summer. Have replaced the radiator twice and the thermostat as well as the radiator cap a a variet of hoses. It only acts up when it gets warm and does it even though I don't use the A/C. I'm a single mom, disabled and I depend on this car for everything. Please help.
(Please forgive if I posted this twice. Trying to figure out the site for the first time. Thanks in advance to anyone who can direct me as to what to look at next.

Re: radiator on 1993 Cadillac Sedan Deville boils after 2...
I think you are trying to say the car overheats. Is that correct ? If YES, I would get some help in determining whether the radiator electric cooling fans are operating, When you say " acts up " , exactly what is occuring. Hope this helps

Step_1 disconnect inlet (top hose) & outlet bottom) hose. I'm assuming you're replacing a corroded radiator. They now offer copper or plastic radiators that have high resistance to corrosion. If you replace with alluminum or steel radiator, do a flush job yearly with replace with the green radiiator solution or the red one if you replaced with aluminum radiator.
Step_2 disconnect the electric fan. first unhook the wire connection, then loosen the 4 screws that's holding the fan assembly against the radiator.
Step_3 Loosen the bolts holding the radiator unit. When re-attaching the new radiiator, install new hoses as well. Fill the radiator through the pressure relief cap with 60-40 radiator to water mixture. The instructions say 50-50, but 60-40 is a stronger solution that prevents freezing, boiling, & corrosion buildup. It there's a coolant filter, replace this unit as well. It looks like an oil filter cartridge.
Preventive miantainance: Perform a coolant flush every 50K miles. Most car manufacturers recommend 30K miles or 2 years, which ever comes first, but that's to boo$t revenue for car dealership service centers. IMO the max is 70K or 2 years. When you notice the temperature is overheating in the summer months, an engine radiator flush AND replacing the thermostat is the solution. Most shops will say "you need a new water pump" and the scammer had not even performed a diagnostic test. The water pump will last the life of the engine (140K+ miles) unless the car had run dry without radiator fluid. The radiator fluid lubricates the water pump. Running the engine dry (or low of) without radiator fluid damages the water pump. Running tap water instead of 50-50 or 40-60 radiator fluid mixture will also cause premature wear on the water pump because water by itself is insufficient lubricant on the water pump.
Hello: Drivers side under the hood follow the top radiator hose from the radiator to the top of the engine, remove hose from adapter on the engine, remove the two bolts holding the adapter, the thermostat is under the adapter. When replacing be sure to install it the same way the old one came out.
First, provided their are no visible coolant leaks and/or loss of coolant with no signs of leaks, I would thoroughly flush cooling system and replace coolant, then check and/or replace thermostat (you can place thermostat in boiling water to check for proper function), if you have tried these 2 steps and still are experiencing overheating you may need to replace your water pump which can be a tricky job if you're unfamiliar and try to do it yourself, however, I could walk you through it if necessary. Also visually check your radiator hoses for bulges, wear ,etc along with heater hoses etc. You may want to also check radiator fins to see if they are dirty/obstructed and clean if necessary. Let me know if I can assist you further and how it works out
I assume motor tune or other mechanical condition is not causing the problem.
Yes, the thermostat is a common cause of overheating - replace the thermostat.
Check operation of the radiator cooling fans is ok.
Check the coolant pressure cap is serviceable & of correct rating,
Ensure cooling system is correctly filled, bleed off any airlocks as necessary,
Ensure radiator hose on suction side of waterpump is not collapsing at engine revs above idle (due softening),
Check radiator cooling core is not blocked internally or externally.
If the motor has been severely overheated, the head gasket could be blown - look for combustion gas bubbles in the coolant resevoir.
Entirely possible and in range. Depends on outside temps and type of driving. The radiator is colled by electric cooling fans, controlled by temp sensors. Fans should come on automatically when a/c is turned on
