OVER HEAT PROBLEM

[drthrift035]

Can a faulty radiator cause an over heat problem ? Under what circumstance can I flush the radiator as opposed to changing it ? Please let me know thanks.

Yes, Over time the radiator can start to lose its ability to transfer the heat away from the coolant.

Also blocked ratiators can cause overheating, lets not forget cooling fans that are not working.

Flushing it wont harm it but it is best to be done at its service interval.

Make sure you bleed any air out.

Some cooling systems also use hard plastic parts that can also deteriorate over time. A few items to check:

• The plastic connections on your radiator that attach to the hoses. Over time, these can literally break into small pieces, thus compromising a secure connection with the hose.
• Thermostat housings made of plastic can eventually crack, leading to leaks and insecure connections with the hose.
• Coolant overflow tanks and their connections with the radiator can also become compromised, causing leaks and then overheating.
