Honda Radiator Problems

Bad radiator fans, faulty radiator caps, defective drain plugs, antifreeze leakage, damaged engine blocks and many others are some of the common Honda radiator problems. Usually, when these problems arise, contacting an Expert becomes very important as it helps to cure a particular issue in the best possible manner. Below are frequently asked questions on issues relating to Honda radiator problems that have been answered by the Experts.

What could cause a Honda radiator top to be hot but the bottom to be normal even after replacing the thermostat?

This could be caused either by a blocked radiator or a broken water pump impeller. The best recourse would be to troubleshoot the components to figure out the true fault. An Expert help is recommended in a repair like this.

What could be the reason for an A/C to fail to work with a replaced Honda radiator?

Most commonly, it could be an unplugged pressure switch on the A/C line or a disconnected radiator fan. In some cases, a blown fuse could also be the reason. Troubleshooting with an Expert would be the best way to resolve the issue.

What will cause a Honda radiator to overflow to the top while filling?

A faulty radiator cap can cause this to happen and will need replaced. However, it would be a better idea to test the component before replacing it. An Expert may be better suited to aid help in this repair.

Why would antifreeze fail to get sucked back into a Honda radiator when cooling down?

This could be from a small head gasket leak. Using a leak tester, have the gasket checked for any leakage to ensure if this is causing the problem. An Experts help is highly recommended to fix the issue.

What are the causes for a Honda radiator hose to seem flat, the antifreeze to be low and the overheating light to fail to appear?

A low cooling system, a hose or internal coolant leak or a blown head gasket could be a few possible causes. Therefore, it is highly recommended to troubleshoot each of these components to find out the exact cause of the problem. Seek an Expert’s help if needed.

What is the reason only the Honda radiator fan operates when turning on the A/C?

This could happen when the coolant temperature sensor is at fault. Thus, replacing the coolant temperature switch is the best available repair option. Consulting an Expert for a proper guidance would also be a good idea in a case like this.

What components would a person need to check to fix an antifreeze leakage that persisted even after a Honda radiator replacement?

Radiator cap, radiator drain plug, oil, overflow bottle, any greenish color around cylinder head and engine block, thermostat housing and bleed bolt all needs checked to pinpoint the root cause of this issue. An Expert’s insight could be sought, if required.

Why would a Honda radiator fan fail to operate?

Many times, trapped air inside the cooling system could cause the issue described. If this is the case, the best course of action would be to bleed the air out of the cooling system.

Often, car owners may not have the required experience to fix a problem on their own. When that is the case, consulting an Expert is highly recommended as they would not only offer the best tips for repairing a problem but also help in providing the correct insight to the probable causes that might lead to causing the issue. This will help to troubleshoot the problem and find out its root cause in an effective way.
