Overheating

I recently noticed that my YJ has been running rather hot lately and I'm not sure why. I flushed my radiator and put brand new coolant in it and its still doing it.

I haven't bought a new radiator yet because I wanted to see if anyone else had any ideas. Also, when I turn the heat on to bring the temp down, I notice the gauge will go up slightly. Thanks!

Hope thats not your problem but if it is there are plenty of hood radiators out there!

Fixed my problem right away. Haven't had any issue since the swap.

Did you change out the thermostat? That's a cheap and easy fix, if that is the problem. But look into your radiator too.

Yea I noticed a lot of that white crud in my radiator when I flushed my radiator out...I guess I'll look into getting a new one. Thanks!

I got one from QTec for $150 to my door but almost wish I'd gotten a little better one since it has plastic ends on it. I know that's how a lot are made now but I'm planning on doing a rock guard mesh behind the grille now just as an added help.

Also, sorry for my late-night-misspelled-extra-letters original post....

Check out Champion aluminum radiators on Amazon. All aluminum, no plastic , a 2 row will run about $150, 3 row about $200. I have a 3 row ordered.

What's the difference between them?

Row is how many rows of tubing run through the fins. Technically the 3 row will cool better. I say technically because it depends on how big the tubing in the row is. A very large one row tube might cool better than a small tube two row. Since these are built by the same company I would bet the tubing in the rows is the same size so the three row has better cooling. I run in the desert a lot so I'm looking for the best cooling for the money, if you are in a milder climate two rows are fine.

I'm in New England so I'm only having the overheating problem now because its been so damn muggy lately but I think I'd still probably go with the better one because it can get up to around 100 at times.
