    I have a bravada 2003. With which I intend to pull a pop up ( still looking). The ones I am looking at are about 3000LB Max weight. I intend to fit a transmission cooler. Do I need to fit an oil cooler as well?
    I have posted this similar question on other forums.
    Cheers

    Not likely, especially pulling in flatland areas. Most popups pull pretty easily. Which engine do, you have? What answers have you gotten from the other forums? BTW, welcome to this forum from N. central Illinois.

    Just worry about coolant temp, if the cooling system does it's job the engine oil will be ok

    Personally, I wouldn't bother unless you develop a specific issue while towing. Do you have a coolant temp gauge? I'd invest in a cheap Bluetooth OBDII scanner and monitor all the sensor outputs (with a smart phone) before I invested in an oil cooler.

    Exactly...if anything, get a higher core count radiator.

    Many Bravadas had oil coolers from the factory. Look at the radiator. Aside from the radiator hoses, there will be two lines hooked to on end of the radiator (I think passenger side). These are for the transmission. If there is another set of lines on the other end of the radiator, then you have an oil cooler already.

    I had a 2002 Chevy Trailblazer and still own a 2004 Trailblazer. It seemed like they all had trailering packages that included both coolers like you found. I can't imagine GM not including the trailering package on the Bravada. Do you have a factory installed hitch and 7 pin connector?

    Just make sure that the other lines you are looking at are not for the AC condenser which is in front of the radiator.

    That would be a transmission cooler not an oil cooler. . Oil cooler will be a small aux. type rad sitting in front of the ac condenser, not to be confused with the aux tranny cooler which will also be mounted infront of the condenser. .
