Finally completed my 5 lug conversion. But why is my oil temp goes up faster than before. Is it because I have a lower diameter and wider tires? Or just a coincidence that after my 5 lug conversion there was another issue that makes my oil goes up faster than before. On the same weather condition around 65 degrees F, I used to drive my car for about 3 miles around city which my oil temp does not goes up immediately and I only get around 180 degrees but today I drove it and my temp went to 200.
Any experienced you have had or anyone can help me figure out? Thanks again my fellow teeners and God Bless! |

You're running at a higher RPM for the same speed due to the lower profile tire. You're probably shifting up because of it. I know this doesn't seem like it should make that difference, but if you had a cylinder head temperature gauge you would see that head temps go up dramatically when you are in 5th gear going up a hill. As these temps go up in the heads, the oils job is to haul away that excess temperature.
The solution is to keep the fan spinning. (IMG:style_emoticons/default/driving.gif) downshift. |

You're running at a higher RPM for the same speed due to the lower profile tire. Not if you're using the speedometer to tell your speed. The stock speedo only counts tire revolutions. Tire size can change until the cows come home and the speedo will give you the same reading for the same RPM in the same gear. If you're using a GPS speedo, or judging by local traffic speed, that is a different matter. --DD |
