Guess you did not get the same lines as what you had. You got the length but not the correct thread type for you car. Most USA equipment runs BSP pipe fittings but imported units run metric. have some one apply a thread gauge to your fittings and compare to old fittings and get the same threads

You will probably be better off just going out and buy what you need all and all. You should need a new o-ring and gasket for the base plate and new o-rings and clips for the lines (to the adapters).

SOURCE: 99 suburban leaking from oil cooler fitting on radiator

It sounds like you might have a crack in the plastic tank of the radiator. If the line was leaking, I would think you'd see some oil leaking. Any anti-freeze leaking? When the truck is cooled down, I'd check the anti-freeze and oil level.

SOURCE: oil cooler above oil filter is leaking how do you

There is a spring clip that holds them in. If you buy a new line assembly, they usually come with a plastic tool to release the clips. Once the clips are released, you usually have to pull and wiggle the line to get it to come out of the fitting.

1998 ford e250 transmission fuild in radiator if line leaks which one would it be i have new radiator hoses

There is a "loop" inside your radiator for the transmission oil cooler. If the cooler is leaking inside of the radiator, you will have a kind of funky sludge in your engine coolant. For what it costs to disassemble your radiator and replace the transmission oil cooler, you can purchase a new aftermarket radiator with one already in it.

How do you replace the transmission cooler on my 89 oldsmobile cutlass supream

Your trans cooler is located inside one of the radiator tanks and would be expensive to replace.
You can either replace the radiator with new or used or cut the lines and install an external cooler as is used for towing. If the cooler in the radiator is leaking, you need to flush the system to remove as much oil as possible or it will cause hoses to soften and fail. Also wise to change trans fluid as well.
Always use double clamps when running rubber lines for cooler so they don't slide apart under pressure.

Replace radiator

easy job considering ,i done one a while back but the cost of the radiator was astronomical just over 500 euros ,remove the fan on the back of the radiator ,the top piece of metal over the top of the radiator ,and comes out but the problem i had was with the hoses as they have a sort of push in clamp ,also the oil cooler feed pipes from the auto box and the engine oil cooler pipes ,now the engine oil cooler connections were just screw on but the gearbox cooler pipes have a special plastic retaining clips and these broke on me and the only way i could repair them was to buy new ones which come with the whole pipe from the gearbox and they were very expensive indeed ,also their are a few different versions as well ,all this because of a silly plastic clip .Also i had to unbolt the AC radiator from the main radiator as well .but the hardest part was the gearbox cooler pipes

Oil leak after radiator change

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.

Oil cooler line replacement on a 1998 Suburban How to get the lines off of the oil pump

Ok...answer to the question about how to remove the oil cooler lines from the oil filter housing. Once you remove the oil cooler line, either upper or lower (Or both) from the radiator. By the way, I have a 98 GMC suburban 2wd 1500, I was able to just remove the fan housing and unbolt the fan by the four bolts behind the blade, this gave me the room to remove bottom half of fan shroud.
Once lines disconnected from radiator, there is a retainer clip that holds the hose into the nut that is screwed into the oil filter housing. I doused the nuts with WD40, then removed the clip with a screw driver. BE CAREFUL not to let the clips get away from you because it would be a pain to replace. Autozone does not carry nut nor clip!!!!! The hoses are held together by a clip and attached to a bracket as you follow the line toward the front of the truck.
Once clips are removed, tug on each line individually away from the nut screwed into the oil filter housing and wahlaa. Remove the nut and clean all the old teflon tape off with a steel brush and WD40. I reinserted the clip back into the nut and with the new oil line in my hand, pressed the line into the nut with the clip in place. This way you can see how the nut and clip lock the hose in place. Enjoy and I hope this helps you out.
Oh.....use teflon tape on the radiator treads as well as the oil filter housing threads. Install starting at the radiator housing. Snug the bolt (1' 1/16" socket) with the retainer clip inserted.
