2008 impala LT 3.9L engine
I have a transmission cooling line leak at the metal to hose crimp fitting. It is the hose that connects to the upper radiator location. Planning to replace the hose & wondering how big of a job it is & if there are any surprises to expect. I’m familiar with the quick disconnect fittings & tool used to disconnect the hoses from the trans & radiator. Not sure how much fluid I should expect to loose or if I should replace both hoses while I’m at it (125000 miles) or should I replace the fittings as well. Any advice would be appreciated.

Re: 2008 impala LT 3.9L engine
transmission / oil cooler lines not going to loose any fluid when replacing.
GM steel to aluminum connectors are leaking all the time. I have a 1996 Impala .. my oil cooler lines do leak many years ago. I put strong clamps over the soft aluminum connector and the leak does not drip.. replacing these hoses/lines will be a hard job because of the removal. also the new replacements will leak soon. |

Re: 2008 impala LT 3.9L engine
It was a pretty easy fix, $25 for a new hose and about 2hrs of my time. Found that the special tool for disconnecting the hose from the radiator and transmission really didn’t work very well; I ended up using a dental pick to remove the retainer. The rest of the job was pretty straight forward. New NAPA hose came with lifetime warranty, hopefully it will last another 100K miles
