Radiator issue

I filled my radiator with coolant, didn't notice any leaks, yet my temp gauge goes to hot after a few minutes of driving. Doesn't happen while idling though
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
If the cooling system was "empty", it has to be re-filled while purging trapped air. Some vehicles are equipped with purge points. If there is trapped air in the cooling passages, that can cause overheating as trapped air impedes coolant flow. If there is no trapped air in your circumstance, among the most common causes of vehicle overheating are a stuck closed thermostat, a partially plugged radiator, a defective radiator pressure cap, a water pump that is not driving at engine speed due to a loose drive belt and/or a collapsed lower radiator hose. Operating while overheating is a significant cause of engine damage, due to the warping of the head and/or block, and so it is recommended that you request an engine overheating diagnostic. The responding certified mechanic will identify the root cause(s) of the overheating and give you an estimate of the cost to get the faults repaired.

The most common reasons a Honda CR-V is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
There`s a leak in your cooling system – Most of the time, a leak in the cooling system is what causes your car to overheat. The radiator, water pump, hoses, thermostat housing, and head gasket are all cooling system components that can cause leaks.
The Honda CRV can run for well over 200,000 miles and, if maintained with a lot of tender love and care, it can keep chugging along even past 300,000 miles. Like all of Honda`s vehicles, the CRV can last for such a long time because of the craftsmanship and high-quality materials that are used for its construction.
Your vehicle can overheat for several reasons, such as lack of coolant or a mechanical problem. The only indication may be the temperature gauge climbing to or above the red mark. Or you may see steam or spray coming from under the hood. In either case, you should take immediate action.
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.
A cooling system leak is the most common cause of an overheating engine.
It has been extremely reliable never having any engine issues. I have kept the recommended maintenance up on the vehicle. It does not have a powerful engine but does get good gas mileage.
Among SUVs, the Honda CR-V has a reputation for being exceptionally reliable. The number of miles you put on your automobile each year and how well you maintain it will affect how long it lasts and the vehicle`s quality. Still, with proper maintenance, a Honda CR-V can be extended to between 250,000 and 300,000.
CR-V shoppers and owners can be confident that 2005–2006, 2008-2010, 2013, 2015-2016, and 2018–2021 are the best years for this compact Honda crossover. However, engine troubles and other problems suggest staying away from the 2001-2004, 2007, 2011-2012, 2014, and 2017 CR-Vs.
When your coolant is running low, the engine can overheat or even seize up. If the metal gets hot enough, a piston can weld itself into the cylinder. If this happens, your engine is likely destroyed.
3. Check and add coolant (if you have it). If your coolant level is low, a quick top-off could help protect your engine and prevent overheating until you can get things fixed. However, this step won`t do much good if a coolant hose is clogged or the source of your troubles is a broken radiator fan or water pump.
The most common reasons a Honda Civic is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
Like any internal combustion engine, your Honda gets hot.
Technically speaking yes you can use plain water in your cooling system but it isn`t recommended as a long term solution and certainly not in extreme weather conditions.
Only Use Water In The Radiator In An Emergency

If it`s really low or actually empty, you need to add fluid to your vehicle. While it`s ideal to add a 50/50 mix of coolant and water (or a pre-mixed coolant), if you absolutely have to keep driving, you can add water to the radiator to get you to your destination.

One way to check for proper coolant circulation is to check the upper and lower radiator hoses. The upper radiator hose should be hot, around 190–200 °F. (The safest and most accurate way to get this temperature reading is with an infrared thermometer.)
Car overheats but no leaks have many possible culprits which include a clogged radiator, a faulty thermostat, air trapped in the cooling system inhibiting coolant flow, a bad water pump, malfunctioning cooling fans, plugged hoses, or a broken serpentine belt. A failing head gasket could also be the cause of this issue.
The EPA rates the 1997-2001 4WD Honda CR-V with either a manual or an automatic transmission at 19/23 mpg or 12.4/10.2 liters per hundred kilometers. This means you can get up to 300 miles to a tank with mostly highway driving.
Answered by CarsGuide. After that (from 2001 onwards) Honda fitted the K Series engine to CRVs, and this engine used a timing chain which should be good for the life of the engine.
The Honda Civic earned its reputation as a reliable daily driver early on. Older model years can easily last over 100,000 miles, and some have pushed odometers past 500,000 miles.
Honda is recalling nearly 564,000 of its older model CR-V sport utility vehicles because road salt can cause the frame to rust and rear suspension parts to come loose.
If you`re looking for a more affordable used Honda CR-V then a second-generation vehicle could be the ideal choice. The 05 and 06 models in particular have very strong Honda CR-V reliability reviews. In addition to being highly reliable, they also offer great fuel economy and strong engine performance.
What is the best 2023 Honda CR-V trim? At Autotrader, we feel the best CR-V trim is the Sport Touring. Yes, it`s the most expensive CR-V, but it offers a host of great features and superior fuel economy. If a hybrid engine isn`t high on your must-have list, we`d go with the EX-L.
Yes, it is! In fact, RepairPal`s reliability rating is high for this affordably-priced Honda SUV. The CR-V has an overall reliability rating of 4.5 out of 5.0 or “excellent,” and ranks second out of 26 evaluated compact SUVs. So it`s definitely a reliable car and an excellent investment for Red Bank drivers!

Car jerks when accelerating in reverse & makes grinding noise. Is this a transmission or computer issue?
ANSWER : Hi there. Typically when you hear a grinding noise when you move forward or in reverse it’s usually an indication of a gear fault either in the transmission or another driveline component. If this occurs only when in reverse, it’s likely a damaged reverse gear. It is also possible that it’s a hydraulic fluid issue not supplying enough lubrication or pressure inside the lines to fully open the gear. I would recommend having a professional mechanic come to your location and complete a car is hard to shift inspection, so they can diagnose the source of your issue and recommend repairs that should resolve this problem.

I have issues with my radiator and radiator fan assembly.
ANSWER : You are correct in thinking that the combination of leaking radiator and non-functioning cooling fan is contributing to your overheating issue. Generally, modern radiators are not repairable and will need to be replaced entirely. The cooling fans can also be sourced from a used parts dealer. It will be used, but less expensive than a new set of fans. Replacement just means that it is designed just like the OEM unit and should fit perfectly. A certified technician, like one from YourMechanic.com, will be able to inspect or replace these components for you, if you are not comfortable doing the job yourself.

Radiator / heater core issues 2002 Dodge Ram 1500
ANSWER : Hello – these two unfortunate events are probably only related in the sense that they are both caused by advanced mileage and age. New radiators utilize plastic end tanks that are crimp-sealed onto an aluminum fin section. The plastic in the end tanks gets brittle with heat and age, the thin rubber sealer in the crimp deteriorates over time and heat cycles, the rubber radiator hoses get soft and weaken with age, etc. Replacing all rubber hoses (fuel lines too) at this point would be minimum maintenance to avoid other potential near-term failures. You pretty-much have to replace the radiator and major hoses in any case to sell the truck, so fix those, get a pressure-test for diagnosis of a possible head-gasket, then make a choice.

Overheating issue with my 2007 Chrysler Sebring
ANSWER : The first thing is a proper diagnosis will not only verify the complaint but will locate the cause of the problem for you so you can decide to fix it or not. When an engine overheats for no apparent reason then the thermostat is the most common cause next to the cooling fans not coming on. You will need to have the computer tested to see if the fan motor is bad or the computer is not powering on the cooling fans. A test is needed to isolate the cause. I recommend having a mechanic like one from YourMechanic to come to you and diagnose the overheating so you do not drive the vehicle causing engine overheating damages.

I have a leak in the coolant system that I have narrowed to I believe is the water inlet tube off of the lower radiator hose.
ANSWER : First off, I would say it would be best to pressure test the cooling system to verify where the coolant is coming from. With the complexity of repairs to the cooling system on this vehicle, it may be worth the time spent to pressure test the system before tackling the replacement. Now then, as far as replacing the o-ring seal on the water pump inlet tube, it should really only require the removal of the bypass hose, lower radiator hose, and the two (or three, depending on manufacturing changes) mounting bolts that hold the inlet tube to the block. I personally would go ahead and replace the tube while I was there, instead of just the o-ring. Granted, this doesn’t mention what it will take to get down to the inlet pipe, but this is all it should take once you have access to it. If this is something that you feel you could use a hand with, consult with a certified mechanic, like those available at YourMechanic.com.

Replaced the radiator but now my can is running hot. Never had this problem until the radiator was replaced
ANSWER : There area number of things that can make your car run hot such as low coolant levels, a faulty thermostat, or a failing coolant fan switch. As you may know, the coolant fan switch helps to maintain the proper coolant temperature by turning on and off at specific temperature thresholds. When this switch is not working properly, this can cause the fans to come on intermittently, all the time, or sometimes not at all. When this happens you will notice a temperature spike and drop occasionally as the fan comes on and off. When your thermostat is not working properly or is stuck closed, this will not allow the coolant to properly circulate through the engine, which may cause the engine temperature to fluctuate erratically or in some cases just remain hot. I would suggest having an expert from YourMechanic come to your home to diagnose your cooling system.
