Already has one installed from the factory. Fancy aren't they?
Pulling a heavy load will cause it to overheat. I suggest you have the fluid and filter changed and then install a transmission cooler. Very inexpensive and it will help when towing. Also check the cooling fins on the factory transmission cooler and make sure they are no clogged with debris.
The 2004 Hyundai Santa-FE has a 5-speed manual.
The heated transmission oil flows through the cooler, and that heat is exchanged to the ambient air which flows through the fins of the cooler. The rapidly cooled fluid returns to the transmission.
The 2004 Santa Fe transmission doesn't have a serviceable filter. There's one deep inside the transmission, but the transmission needs to be removed and disassembled to get to it. The only time that filter would be replaced is if the transmission were overhauled. This is the answer I found online, and after trying to change the filter on a 2002 Santa Fe, I believe it completely.
Some do and some don't. Crawl under the vehicle, follow the transmission lines to the radiator, and see if there is an secondary cooler anywhere. If it came with the factory towing package it does.
The most common leak points are the cooler hoses and the axle shaft seals.
The overdrive allows the engine to run at a lower RPM on the highway It saves gas , the transmission will run cooler etc.
Dealer use the tranny cooler lines to completely flush the system. This changes he fluid in the torque converter as well as the transmission. It's worth the extra investment.
Yes it does. If you crawl underneath the front and look up you will be able to see it. I was shocked to see that the 2004 Ford Explorer 4.0 liter does not use the typical cheap in radiator cooler. It actually has a good sized stacked plate aluminum cooler that is mounted between the radiator & a/c condenser. It runs the entire length of the radiator. I was going to add an auxiliary cooler until I saw the beefy factory unit.
2004 sedona's have a tanny cooler in the front to keep it from overheating like a small rad if one of the lines are bad or damaged it will from the bumper (front) area
Start the car after it has set overnight. Run for a few minutes while in drive. Shut of and feel the 2 lines. The one that is hot is the inlet.
The 2004 Hyundai Santa-FE has 16 valves.
