just do what you want, then if you crack the rad you will understand what these experienced men are attempting to tell you.
have at it and good luck.

 

Because of the lock title, when you try to screw them out, it can crack the lower tank and create a COOLANT leak! Good luck

 

you keep saying lock title. do you mean lock Tite?

 

Just the darn spellcheck..........tite not title........had to override it even this time! Best to you and thanks for paying so much attention. Sorry you aren't familiar enough with this topic to know that it is LOCKTITE! Wrench on.

 

thanks a bunch for the heads up though. very much appreciated.

 

How is the install going?

 

The most obvious reason NOT to attempt to remove the transmission cooling line fittings from the bottom of the radiator is that they are meant to be permanent and are actually line clips NOT threaded fittings. Once you unscrew them from the radiator, you will play hell getting anything threaded back into the radiator tank loop they came out of because it will no doubt move and not be accessible through the hole the retainer fitting came out of.

 

thanks. yeah. I have the transmission oil cooler installed as of saturday. The only thing not hooked up yet is the fan.

 

About those fittings... I have replaced many of those radiator fittings, with new ones, without any problem. Do I worry the rad will leak after? Hell yeah! Always relieve the rad pressure first before attempting removal of the fitting. That seems to work. Also replace one fitting at a time to help hold the cooler in place. Never has the inside cooler dropped, yet. Just a little tid bit of experience.

 

Is this the case for H2s as well? Based upon my initial visual assessment, doesn't seem to be the case. However, I'm new to tinkering on Hummers, so just trying to learn as I go.


Thanks
