I have a 2001 trailblazer that has 102,300 miles and is in great shape, I have noticed oil on the garage floor. There are 2 lines with crimped ends that run under the radiator that look wet. It is hard to tell if its trans fluid or motor oil. I checked all the fluids and they are all to the proper level. I want to fix this before it gets worst. Any Idea where these lines can be bought so I can replace them soon.

 

There are 2 sets of hoses (2 hoses each set) for the remote oil filter behind the radiator. Open the inspection door for the filter, and determine which set is leaking: One set runs from the radiator to the filter block (this one is fairly easy to replace), the other set runs from the filter block to the engine block on the passenger side (harder to replace, engine needs to be raised - pass. side mount removed - to get at engine block fittings).

Cooler/filter blocks line sets available at most major brand parts stores.

 

Thanks for the info. Im going to clean everything off with degreaser then investigate what hose is leaking.

 

if its a 2wd its pretty simple more so than 4wd
Autozone carries oil cooler line about 50.00

 

Also, coolant leaking from engine, specifically LIM mixes with old oil and dirt and makes itself look like oil on the bottom of the engine. How has your coolant level been?

 

Vegie 2, Its a 4wd needed in WI. Thanks for the autozone tip.

Guns, Im going to clean everything off and check for the cooling leak also. I had to add some coolant about 6wks ago. I thought it was because I didnt add enough antifreeze when I back flushed the heatercore. Thanks!
