    Temp going up when going over 60 mph in highway for long time

    Interesting. A weak cap typically releases coolant through the cap (it will also have a soft rad hose when at operating temp) vs having bubbles come up. Bubbles in the cooling system (assuming it's not coolant being pushed into the expansion tank through the bypass, splashing around and creating...

    Temp going up when going over 60 mph in highway for long time

    Well if your vehicle has a known head gasket leak, then you have your over heating issue..... High RPM, and in cylinder pressure can definitely over come coolant pressure and cause over heating, especially at highway speeds. It is possible to have combustion chamber gasses enter the cooling...

    Temp going up when going over 60 mph in highway for long time

    Thermostat (spring side) will be facing the engine. If it's facing the rad, then it's backwards. Did replacing the expansion tank cap making the bubbles go away?

    Temp going up when going over 60 mph in highway for long time

    You have been given a lot of good ideas here. Have you notice the coolant boiling over when transitioning from highway, then coming to a stop light for example? Once you verify fan(s) and fan clutch are all functioning, including rad (which is said to be new), thermostat and water pump are good...

    2004 Liberty Sport

    What are you using for the front to hold the winch? The front looks pretty clean all considering.

    Question about 4.7L V8 in the WJ/WK/XK — need advice

    You can try using a synthetic oil or a semi synthetic oil to help with oil flow/cooling. Only down side is with the consistently sized molecules some run into burning oil. Mine doesn't burn, but my nieces does.

    NEED 4.56 RING AND PINION FOR MY KJ

    Your diesel Liberty should already have 4.10 gearing. Search your vin and verify the exact vehicle configuration and options or contact your local dealer.

    What did you do to your jeep today?

    Good work. Try with a little less solder next time. I will keep the same strength, but will allow the wire in that spot to flex, and be less likely to become brittle and crack. We can't have ourselves working more than we need to:p

    What did you do to your jeep today?

    Yeah no more than 8000km Fluids fall under emissions, so every manufacturer is trying to stretch them out and much as possible and those are the issues you get. Make it to warranty then not your problem. On our oil change stickers we will put 8000km if it's a synthetic oil. Some customers get...

    What did you do to your jeep today?

    Yeah good quality fluids will clean it out good. Turbos love clean fluids, they spin up to super high RPM, and historically were oil cooled. Yours is water cooled, but good oil will also aid in the cooling and I'm sure the bearings will a hair happier. At some point you will need to de-carbon...

    What did you do to your jeep today?

    Hard to say. Direct injection + turbo (my wifes engine) is a recipe for carbon. Toyota has largely avoided carbon issues with the dual injection system, but not many people are doing that. These engine need to get hot and they need to be driven hard. I actually haven't seen many issues with the...

    What did you do to your jeep today?

    Welcome to modern turbos! Wifes Mazda 4 cylinder turbo puts out more power than my old Durango 5.9L, and has the ability to pass a gas station without needing more fuel.

    What did you do to your jeep today?

    OEM bushings are in stock at various NA DC'S. Just call your local dealer and order some. Mine came next day(depending on cut off time of the DC). Oddly enough Portland is our supplying DC and get here faster than the neighbouring province.
