Can a radiator from an 02′ DeVille work on a 99′ DeVille?

Can a radiator from a 02' DeVille fit and work properly on a 99' DeVille??..

My car has 170000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
The radiators used in the 1999 versus 2002 model years do not interchange. The design and fit is different and the catalog part numbers do not interchange. Radiators these days have come down in price. The radiator on this model is not hugely expensive and frankly you are better off just installing the new, model specific part as that will avoid lots of installation and reliability headaches. Requesting installation of the radiator on a mobile basis will save you even more money. If you desire a mobile installation from a certified mechanic, please use YourMechanic’s radiator replacement service page to obtain a written quote and schedule the service. If you have further questions or concerns, do not hesitate to re-contact YourMechanic because we want you to make the most of your repair dollars and help you to get the best possible results.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

The most common causes of overheating include low coolant level (including that due to leaks), a faulty thermostat, a plugged radiator, a faulty radiator pressure cap, collapsed hoses, non functioning cooling fans, and a faulty water pump or drive belt.
Great gas mileage @ average 22mpg. Excellent power from the Northstar engine, no mechanical problems.
The popular 2000 and 2002 Cadillac DeVilles are prime casualties, with the engine tending to overheat due to a leaking head gasket. Alternatively, a water pump leak could be preventing your coolant circulating freely through your engine.
The most common reasons a Cadillac DeVille is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
Normal operating temperature should be between 160 and 190 degrees depending on what thermostat you have installed. If it is running much hotter than 190 then you need to service your cooling system.
The naturally-aspirated 4.6L Northstar V8 LH2 made 320 horsepower and was available in the first-generation Cadillac SRX, Cadillac STS, Cadillac XLR and Chinese-market Cadillac SLS. The range-topping variant was the supercharged 4.4L Northstar LC3 used in the Cadillac XLR-V and STS-V.
Adding coolant does nothing to address the problem that caused your engine to overheat in the first place, but it often allows you to drive safely to the nearest repair station. “A professional will need to inspect your car`s cooling system,” says Reina. While driving, keep an eye on the temperature gauge.
The block is believed to be capable of expansion up to 5.4 L, though no such engine has been produced. The Northstar was on the Ward`s 10 Best Engines list for 1995, 1996, and 1997.
Why is my car overheating but it has coolant in it? It could be that the coolant concentration is not correct, or you may have a bad thermostat, a failed water pump, broken drive belt, or a bad radiator or radiator fan.
If your car is overheating, but it has coolant, these are some possible reasons: Bad water pump. The water pump keeps the coolant circulating through the engine, so if it stops working your coolant won`t circulate and can reach boiling temperatures. Clogged radiator.
Possible causes include a blocked radiator, a coolant leak, a failed thermostat, and a damaged radiator hose.
Leaks are the #1 reason a vehicle begins to overheat. Leaks in hoses, the radiator, water pump, thermostat housing, heater core, head gasket, freeze plugs and a few other things can all lead to problems with the vehicle`s cooling system.
The coolant sensor on the northstar engine in your 1999 Cadillac DeVille is located on the back end of the rear head.
In general, it`s because something`s wrong within the cooling system and heat isn`t able to escape the engine compartment. The source of the issue could include a cooling system leak, faulty radiator fan, broken water pump, or clogged coolant hose.

My dash board don’t work my front light work when I change my light into high beam and my back window won’t go down
ANSWER : As unfortunate as it is, your vehicle would be considered flood damaged. Diagnosing electrical problems in a flood damaged vehicle is nearly impossible. This would take many hours or even days to determine which wiring harnesses and circuits have been affected. Then nearly all of the wiring under the dash would likely require replacement as well as many sensors and switches. On a BMW vehicle, the amount of wires and switches are likely more than that of a lower end vehicle. Due to the inefficiency in cost, you would likely be able to purchase another BMW like yours for less than what it would cost to fix your car. Many insurance companies would consider this type of damage to total out the vehicle unfortuantely.

Windshield wipers stopped working. They’ll suddenly stop working then suddenly start working again. Has been happening for a week.
ANSWER : The problem you are describing likely stems from an intermittent electrical fault in the wiper circuit. The windshield wiper system uses a small electric motor to move the wiper arms that you see on the windshield. That electric motor is controlled through a switch, relay, fuse, and wiring. One, or more, of those electrical components has failed although it is also possible that the mechanical arms are binding (seized, if the lubricant has dried out) thus causing the electric circuit to the motor to overload. Regardless of the underlying fault, if you request a non functioning wiper diagnostic/repair, the responding certified mechanic will get this taken care of for you.

My AC does not always work. If I fiddle with the blower knob I can ususally get it to work on the lowest setting.
ANSWER : Hi There,
It sounds like you may have a faulty blower motor resistor. The highest speed setting may still work because in most cars in the highest fan speed settings the current bypasses the blower motor resistor. In some cars, if the resistor is failed, the fan may stop working completely. Another reason a blower motor resistor may fail is when the blower motor has a mechanical problem or when a foreign object jams the blower motor fan blade and prevents it from spinning freely. This leads to increased current through the resistor and causes it to overheat and fail. I would suggest having an expert from YourMechanic come to your location to diagnose your system to determine what may be causing the fan not to work properly.

All dashboard lights and tail lights do not work after driving through a lot of snow. Headlights work. And brake lights work.
ANSWER : Hello. We’ll be happy to help you. There are a few things that I recommend checking to discover why your lighting system is malfunctioning. The headlight dimmer switch should be checked. Along with the wiring harness above the right front tire behind the fender well cover. Also
the main fuse under the hood should be inspected because other people with your particular vehicle have had similar lighting issues if that fuse goes bad. It will be a great idea to check the rest of the fuses in that area too while checking the main fuse. Once the fuses are checked inside of the main fuse box then I would check the fuses inside of their interior fuse box. The interior fuse box should be located on the driver side of the dashboard near where your legs would be.

Honda Civic 2008. AC stopped working suddenly and engine check light came ON for a day.Next day AC worked and no engine light.
ANSWER : Hi there. In both cases, when an AC system is not working and a warning light is coming on the dashboard, typically a professional mechanic will complete the same initial inspection, which is to download the stored error codes that triggered the warning light initially. This tends to give them an idea as to what is causing the problems. This could be something as simple as an electrical relay that is faulty or loose or an indication of a computer related "glitch". Either way, the best way to move forward is to have a professional mobile mechanic complete a check engine light inspection.

I have a 00 deville I just changed the water pump housing and water pump the thermostat and radiator the upper and lower radiator 2000 Cadillac De Ville
ANSWER : Hi there – I suspect your radiator is clogged or otherwise corroded so that it is not shedding heat as efficiently as it should. Idling with the heater on was getting rid of heat without loading the radiator. When you’re driving, the engine is generating more heat than both the heater and radiator can get rid of. Checking the difference between hot coolant going to the radiator (top hose), and going back into the engine (bottom hose) may show that there is very little temperature difference. This means the radiator is not doing it’s job, and need to be professionally cleaned or replaced. Good diagnostic effort on your part to avoid the obvious "it’s another Northstar head gasket" diagnosis! For confirmation, I would recommend an overheating inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

Will a transmission from a 99 suburban k1500 5.7 for my 99 silverado 5.3
ANSWER : If both vehicles have the auto 4×4 and have the same electronic shift, then they should be the same externally. Internal may have different gear ratios depending on the applications. Look at the two part numbers and you may find that they both have the same one. Look at the transmission code in the glove box on both of them and see if the codes are the same and this will tell you they are the same or different. They should still fit each other.
