Car Care Tips- Too Hot Ridgeline
2011 Honda Ridgeline RT
Leann writes: My V6 Honda Ridgeline has a 115k miles and a strange overheating problem. It seems that the farther I drive the hotter it gets until it overheats. If I am stuck in traffic, the temp gauge shows halfway and will never run hot. Not until I drive on the freeway 4-5 miles, then it starts creeping up until it boils over. If I drive on the feeder road, it starts to cool down. I have tried a thermostat and a water pump with no success. My Dad thinks that the head gaskets are leaking. Could that be the problem?
Mike: I have seen this problem several times over the years. What you have is a restricted radiator. It can keep the coolant temperature at a normal level at lower speeds, but can’t keep up with the thermal load at higher speeds. If you have your technician check for “cold” spots in the radiator’s core, he will be able to locate the places where the coolant isn’t circulating. Then you will find the problem. I would recommend replacing the radiator before you overheat the engine so many times you do end up with a head gasket problem, or worse.
Here is a tip: If your windows seem to go up and down a little slower than they used to, let me tell you a good fix for this. Get a can of silicone spray at the parts store and spray the window run channel to keep it slippery. This way the window slides easier and takes some of the pressure off of the window motor and window regulator. The silicone also helps keep the rubber soft and pliable. If your car is a little older, you can use silicone spray on all of the door seals to help them last a little longer and work a little better.
Mike the Car Guy University: In response to all of the great e mails I get every week, I am planning a series of classes on understanding your vehicle, and using that knowledge to extend its useful life. Details are still being worked out, but the classes will be in a series and hosted by some of the outstanding dealers in our area. If you would like to be notified when I am teaching in your area, just e-mail me and I’ll let you know. MH
