Acura Cooling System Troubleshooting
Is your Acura overheating? Are you looking for a second opinion on the repairs advised? The cooling system consists of a number of components that could fail and cause heating problems. Knowing what is wrong allows you to be sure that the required repairs are being done at the right costs. The recommendations of verified mechanical Experts will guide you to the causes and solutions to your problems.
Read below to see some of the questions Experts have answered.
Why does a 2002 Acura TL 3.2 overheat after driving just a few miles despite the fact that the cooling system has been checked and no problems found?
If there are no cooling system issues, the cause is likely to be leaking cylinder head gaskets that are allowing exhaust gases to mix with the coolant. This will increase pressure in the system as well as heat the coolant excessively. Together these will result in rapid overheating. Replacing the gaskets should fix the problem.
What could cause exhaust gases to enter the cooling system of a 2003 Acura MDX and is there a test for this?
Exhaust gases enter the cooling system when there is a leak from the head gasket or a crack has developed in the head. When this happens the hot gases increase the internal pressure in the cooling system and this, combined with heat of the gas, causes overheating issues. The best way to test for this is to use an exhaust gas testing kit. These are available at most large auto parts stores. The kit will come with usage instructions but in general it will have a blue fluid that is added to the system. If it turns yellow, exhaust gases are present.
If a 2000 Acura TLS dies after the engine overheats, what damage could have occurred and how can it be diagnosed?
Case Details: The engine will not even crank.
When an engine dies because of overheating and will not crank after it cools down, the damage could be serious. If the overheating was because of a cooling system failure, then the pistons may have seized in the cylinders. If it happened because of a lack of oil leading to inadequate lubrication, the bearings may have been destroyed. Pressure testing the cooling system will show if there is a leak. If so, have it fixed and fill up with coolant. Check the oil level and if low, look for and fix any leaks and then top up the oil. Jump start the vehicle. If it still does not start, there is a likelihood of piston and/or bearing damage that will require major repairs.
What could cause a 2002 Acura RL to suddenly run very hot and for the inside of the hood to be covered with fluid?
These are the signs of a cooling system issue. If the coolant level is low the engine and coolant will overheat and the increased pressure in the system will cause the fluid to spurt out of the coolant reservoir or any leaks in the system. A leak is the most likely reason for this to have happened and it could be from anywhere in the system. The common causes are a leaking water pump, gasket, hose or fitting. The system will have to be properly filled and a leak test done. Once the leak is located, it can be repaired or the faulty part replaced. This should preferably be done at a qualified shop. Driving the vehicle in this condition could result in serious engine damage.
What could cause a 1996 Acura TL 3.2 to overheat when idling?
Case Details: The radiator was recently replaced.
One reason could be that the cooling system was not bled or the bleeding was not done properly when the radiator was replaced. Bleed the system and if the problem remains, have a test done for combustion gases in the cooling system. If gases are present, the head gasket may need to be replaced. If this is not the cause, then the water pump may be faulty. Over time, the impeller becomes worn and this will result in low coolant circulation when the engine is at low RPMs as when it is idling.
If a head gasket failure has caused exhaust gases to enter the cooling system of a 2008 Acura MDX, should both the gaskets be replaced?
Since both the gaskets will have been subjected to the same wear, when one fails, the other is likely to follow soon. It is advisable to replace both to prevent a recurrence of the problem.
Can head gasket sealer be used to fix a leaking head gasket that is allowing exhaust gases to enter the cooling system of an Acura?
Head gasket sealers can, at best, offer a temporary solution. The risk is that the leak can begin again at any time and if it is not noticed, result in serious engine damage. Additionally, some of these products are known to clog the cooling system resulting in overheating from another reason. Generally speaking, it would be better to replace the both the head gaskets.
Why is the temperature gauge on a 2000 Acura with 215,000 miles showing the engine is overheating when the radiator and rest of the cooling system all appear to be at normal temperature?
It will be advisable to have the cooling system checked to confirm that there is no actual overheating issue. Once that is done, the temperature sensor and gauge will have to be checked. Sensor failure is more common, especially on vehicles with this mileage. Replace the sensor and if the gauge still shows that the engine is overheating, replace it.
