Has anyone switched to a 2 row aluminum rad and if so do you have any trouble with not enough heat in the winter? 2000 TJ 4.0 with A/C.I should clarify.I have no problems with heat just a leaking rad that needs to be replaced.Just wondered if the thermostat still does it's job with the increased cooling of a 2 row all aluminum.

 

You need to flush the heater core, let me know if you need instructions on how to do so :)

 

Thanks.I edited my question.Not lack of heat.

 

I know this may sound strange to a man lol, but read the instructions that come with the rad! I don't have a good answer for you, if it was me I'd just change the rad and see what happens. If after you burp the engine and its over heating start troubleshooting. It's made for your jeep right? So unless the instructions say otherwise I wouldn't be to worried about it.
