Anyone had this problem and what was the fix, theres 2 lines going into the raidaitor that looks like the leak may be coming from there but i thought they were transmission lines.

 

Hi their is engine oil cooler lines and transmissions cooler lines.

 

Probably the lower transmission line on the passengers side.

 

It's the oil cooler. I put a new clip on it but it didn't help. That's a stupid design. I'm going to see if I can't put some regular hose clamp fittings on it instead of the quick disconnects

 

Myn 2003 h2 hummer has had a problem with the transfer case or it may be the front differential mounting bushing bolt .it has been coming out periodically .the oil cooling line housing that bolt in to the engine, has been bet from the drive line hitting it . To the point the oil shoots out when the vehicle
is started

 

 

1 Fastcobra,

Did you find the oil leak? If so what was it? My wife just called and said she had a oil leak on our 2007 H3. Our son is looking for the leak. She did say the fan blew oil all over the bottom of the engine so he is having a hard time trying to find the oil leak source.

 

I believe it is from AT line to the cooler. Just replace the ''O'' ring inside the tubing oil line plug/....

Step

Drain all radiator coolant.
Pull out the tubing from the radiator plug.
Unscrew the plug using 26 wrench (not really sure bout size)
Once plug removed,look at the plug there is an penny size ''O''ring inside the plug. Get it replace.
P/S I recommend put silicon sealant on the plug tread when installing back.

This steps applies to other Tubing joint which connected to radiator.

Hope this help!!!

 

Thanks! I'll look into that when the wife gets home.

 

yup exactly what I did
