2011 hhr transmission line connections to radiator

Might want to replace the leaking transmission lines. Depending on location or exposure to elements, they may need to be heated to break loose.

Is it the power steering hose or a transmission line.Honda does not usually attach power steering lines to the radiator, but the transmission cooler lines are attached to the bottom of the radiator. If it is the transmission cooler line leaking, simply replace the line from the radiator to the transmission with 1/2 inch transmission line and some new clamps.May want to do both lines while you are making the repair.

Possible leaks are 1. Transmission belly Pan gasket 2. Front pump/torque converter seal. 3. Transmission fluid cooler lines 4. Axle seals at right and left half shafts.

Crossing the lines would not cause a leak. i think you need to take a good look at the lines and see if its the connection to the radiator or a rusted line or bad hose, some of theses came with the trany lines being all rubber hose from ****** to radiator and some were rubber and then change to metal tubing , anyway it doesnt matter which you have but i will bet its leaking from the lines , it may be the line itself or the connection at the radiator, clean the area with some engine cleaner and rinse off then run the engine and watch where the leak comes from, maybe the line just needs tightening. good day.

whoever installed it either did not get the connections tight enough or they have crossthreaded it...undo line that is leaking and attach it again using a little teflon tape this time.. these have to be tight.. also, you may need to check your fluid level in your transmission now also

Nissan Car 350Z & Maxima 1999-06 Radiator - Removal & Installation

1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. Drain the cooling system.
3. Remove or disconnect the following:
   Negative battery cable Coolant reservoir tank and bracket Upper mounting bracket Upper radiator hose Oil cooler lines, if equipped Lower radiator hose Cooling fan and condenser fan Fan motors and shields Radiator

To install:

1. Install or connect the following:
   Radiator Fan motors and shields Cooling and condenser fans and torque the bolts to 44 inch lbs. (5 Nm) Lower radiator hose Oil cooler lines, if equipped Upper radiator hose Upper mounting bracket Coolant reservoir tank and bracket and torque the bolt to 44 inch lbs. (5 Nm) Negative battery cable
2. Fill the cooling system to the proper level.
3. Start the vehicle, check for leaks and repair if necessary.

WARNING Do not remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine coolant escaping from radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.

1. Before servicing the vehicle, refer to the Precautions section.

1. Before servicing the vehicle, refer to the Precautions section.
2. Drain the cooling system.
3. Remove or disconnect the following:
   CAUTION Do not damage or scratch the A/C condenser and radiator core while removing.
   CAUTION Because A/C condenser is onto the front-lower portion of radiator, moving to rear direction should be at minimum.
   Negative battery cable Engine cover Air duct and air cleaner case assembly Bracket mounting bolt for anchoring A/C piping Reservoir tank and bracket Upper and lower radiator hoses Radiator cooling fan assembly On A/T models, A/T fluid cooler hoses. Plug hoses to avoid leakage Cover, then two A/C condensing mounting bolts located in the upper part of the radiator Rotate two radiator upper mount brackets 90 degrees in the direction shown in the illustration and remove

4. Remove the radiator by performing the following:
   CAUTION Lifting A/C condenser should be minimum to prevent a load to A/C piping.
   With lifting and pulling radiator in a rear direction, disassemble lower mount from radiator core support center. Lift A/C condenser up and remove radiator after disengaging the fitting as front-bottom surface After removing radiator, put A/C condenser on radiator core support center to prevent a load to A/C piping, and temporarily fix it with rope or similar means

To install:

1. To install, reverse removal procedure.
2. Check radiator cap for any leaks.
3. Start and warm up engine. Check for engine coolant leaks and A/T fluid leaks.

Hope this help (remember comment and rated this).

Hi:

If you have a leak near the lower radiator connection that just started, it is either a failed hose, or possibly a radiator core leak that is dripping down to that area.
If you havent changed your radiator hoses for awhile, and they feel soft, it isn't a bad idea to change them both. If you drain your radiator to change the hoses, this would be a good time to inspect the radiator, and perhaps you will find the source of the leak.

Make sure you don not run low on transmission fluid in your transmission. Low transmission fluid will cost you a new transmission. You have the transmission line that connects to the upper passenger side or the radiator and the lower passenger side of the radiator. Determine which line has gone bad and you can buy a rubber transmission line hose at most Auto Parts store like Parts Source. Cut off out the section with a pipe cutter that has corroded through and replace with the transmission hose. Make sure you tell them it's a transmission line hose your looking for and don't use any other hose and double clamp with a compression clamps at ether end. If it's the connection at the radiator that has gone bad, replace that end and do that same as you would to sectioning off the the corroded line and try not to have more then 3 inches of repaired section. What ever you do, do not add any stop leak, this will create problems with the shift solenoids and check valves in your valve body in the transmission causing a transmission replacement soon after adding. Good luck and keep me posted.

Before you remove the radiator, check the transmission line connection's at the passenger side. There should be two, one at the top ( in ) and the bottom ( out ). There are only in place by a quick release and see if which line is leaking and replace the line or the O ring that seals the line to the radiator. Good luck and hope this helps. The transmission cooler only runs down the ends of the radiator. Good luck and hope this helps. Keep me posted, be glad to help. 

The radiator has a transmission and engine oil cooler lines to it too. One of the oil lines are leaking, if you know which one that's have the battle. I believe the transmission line is on the passenger sides and the oil cooler line is on the drivers side. Look at where the lines connect to the radiator and see if there is signs of the leak. You may need to spray it down with brake cleaner if you not sure if it's a new leak or old leak from the accident. Good luck and hope this helps. And what do you mean by rear case gasket?? You mean the gasket that connects the transmission to the transfer case, or the rear O ring yoke gasket.
