My 1998 Isuzu Rodeo LS gets hot, then cools, then gets hot and stays hot
My 1998 Isuzu rodeo gets hot after about ten miles or so. It will cool down for a few more miles then get hot again. This will happen a few times then it will get hot and stay hot. My coolant is full. I have new hoses and radiator cap. My water pump does not appear to be leaking. There does not appear to be any leaks coming from the engine. I can let it idle for a long period and it doesn't get hot. But when I get on the road it gets hot! Need to find a next step!
My car has 22700 miles.
My car has an automatic transmission.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
The most common reasons an Isuzu Rodeo is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat. Coolant leak (water pump, radiator, hose etc.)
It sounds like the heater core is clogged and restricting the flow of coolant in the coolant system. There is also the possibility that the new radiator is defective and is causing the car to overheat. The head gasket could also be blown.
Pull over and shut off the car. Allow the engine to cool for at least 15 minutes. Keep an eye on the temperature gauge, as it should move back to a normal range as the engine cools.
Normal coolant temperature will be around 195 to 220 Fahrenheit (approx 90°C) and anything above or below this can start causing problems.
There are a variety of reasons that a vehicle can overheat, such as cooling system leaks, blocked hoses from corrosion and mineral deposits, radiator issues or broken water pumps. Regular inspections may help avoid overheating issues down the road. Come in today for a consultation on your coolant/antifreeze fluid.
Why does my Isuzu`s engine overheat? There are two main causes for engine overheat: The coolant does not flow through the system like it should. There is not enough air flowing through the radiator.
Once the engine reaches operating temperature, the valve will open and coolant will begin to flow through the engine. A faulty thermostat might remain closed even when the engine is hot, which can quickly lead to overheating.
COOLANT TEMPERATURE SENSOR FAULTY: SYMPTOMS
Higher idle speed. Increased fuel consumption. Poor starting behaviour.
There are two temperature sensors in some vehicles, one to send information from the engine system to the control unit and another from the control unit to the dashboard. The device follows the principle of dependence of potential difference in temperature.
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.
Coolant/antifreeze is added to a vehicle`s cooling system, which circulates the fluid throughout the engine and radiator to prevent overheating. If your vehicle`s cooling system is functioning properly, it will effectively reduce the heat produced by the engine and keep everything running smoothly.
On the other hand, clogged injectors themselves can lead to an overheating engine. If your injection system is having trouble releasing fuel, the engine may have to work too hard to compensate. This can cause it to overheat.
3. THERMOSTAT. Most of the rest of these problems will cause a check engine light to turn on, but they could have an issue and not be noticed by your vehicle`s computer. A bad thermostat can improperly regulate fluid, and can lead to overflow.

95 3000gt gets hot while accelerating but not during idle. Also doesn’t reach the red line, but stays a notch or two below.
There is inadequate coolant flow or, less likely, a leak at the head gasket. Remote possibilities include dragging brakes, under inflated tires, and transmission faults. Inadequate coolant flow can be due to a low coolant level, 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. Certain engine faults, such as a leaking head gasket or poor engine running condition can also cause overheating. If you desire that this problem be diagnosed by a certified Mechanic, dispatched by YourMechanic right to your location, please request an engine overheating diagnostic and the responding certified mechanic will get this resolved for you.

97 Firebird engine getting too hot.
The main two reasons that a vehicle will overheat at low speeds but remain cool at high speeds are a clogged radiator or an inoperative cooling fan. I would first recommend driving your vehicle a short distance to get it to operating temperature. Then, stop the vehicle, open the hood, and check to see if the radiator fan is working. If the fan is not working, this is the cause of your problem. The radiator fan’s job is to keep air flow through the radiator when the vehicle is moving at slower speeds. The radiator being cloggeed by contaminants can also prevent air flow through the radiator. I would recommend having your radiator checked for hot spots using an infared thermometer if your fan is working to determine if it is clogged. Consider YourMechanic as a certified professional can come to your home or office to inspect your cooling system for you.
Rear wheel getting hot after caliper and hose replacement
There are a few reasons that a caliper piston might fail to retract and there is also the possibility that the heat is being generated by a failing wheel bearing. If the issue is brake related, pressure in the line might be failing to release (due to a line fault such as a blockage), the pads might be stuck or binding in the torque plate and there could be problems with the sliding pins in the torque plate. Also, you’ll want to check for a parking brake assembly that is failing to retract at that wheel position. To obtain a quick resolution of this, you can request a brake inspection and a certified mechanic will come right to your location.

Why is my air system blowing out hot air in spurts and why is the temperature gauge nearing hot while in use?
This can be caused for a variety of reasons such as a malfunctioning thermostat, a radiator not flowing properly, a faulty coolant temp sensor or AC refrigerant not properly being supplied to the AC compressor. Your car’s AC system puts a heavy strain on your car’s engine when it runs as it requires a lot of power to run. When the AC compressor comes on it puts additional strain on the motor that may be already struggling to stay cool as a result of any of the issues named above. I would recommend having an expert from YourMechanic come to your home to diagnose and repair.
Hey i have a 2000 focus and the heat blows hot but it only stays hot for about 1 minute then it goes cold. I have to wait 5 minute
If your heat blows warm and then cold in addition to the engine overheating, this may very well be a thermostat issue. This may also be an issue of air being trapped in the radiator or heater core. This causes this type of cycling effect with hot and then cold air being blown into the cab of the vehicle. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.
Is it normal for the brakes to get hot or smell hot after the pads and rotors are changed on the rear brakes?
Hi, thanks for writing in. I’d be happy to provide my insight.
From the description of your 2010 Pontiac G6 braking issue, there are a few likely causes. If the piston in the caliper did not move freely than this will allow the brake pad to drag on the rotor. When the pad drags it can overheat the rear brakes and cause them to fail. The caliper will need to be inspected before the vehicle is driven more.
If you would like help getting these inspected, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose these brake problems for you, and make or suggest any repairs as needed.
I had dual cooling fans, the replacement part was a single larger cooling fan. Now I get aengine light about my cooling system. Ho
You should check with the person you bought the fan from. I show a listing of a single or a dual fan system. You should replace the fan with the same as what was removed. You should not use the single fan when you were equipped with a dual fan system. The wiring and programming is different depending on how it was made.
No heat, antifreeze leak, overheating engine
Hi…stop leak products should never be introduced into a car engine’s cooling system simply because such aftermarket products are not a factory authorized or factory sanctioned repair technique. Some factory service manuals are indeed emphatic on this issue. A stop leak product is, in essence, a foreign contaminant and thus has the potential to plug up cooling passageways, the radiator and so forth. The only recognized technique employed by professional mechanics when it comes to a leak in the cooling system is to repair the leak, period. At this point, by far the cheapest and most effective strategy for you will be to have a mechanic identify the leak(s) (via pressure testing, if need be, on a cold engine), repair the leak, and thoroughly flush the cooling system to hopefully remove all traces of the stop leak product. The cooling system has to then be refilled with new coolant, while purging all air, and tested. On a vehicle with over 200,000 miles, it is possible the leak occurred along with other cooling system faults such as a failing thermostat, water pump, and possibly partly clogged passageways, particularly in the radiator. All of that will have to be evaluated to ensure that no further overheating occurs. To get this resolved promptly and professionally, by all means please feel free to request a leak diagnostic and the responding certified mechanic will get you squared away.
