Hi guys,
Picked up a Calmini front front bumper/skid combo and a Champion winch...
Doesn't seem to leave much in the way of airflow. Will I have overheating issues on my 04 auto 4x4? Anyone have experience with that issue. Tell me all will be okay......Please.

Nope, you are going to overheat. You need to drill big holes in the bumper.

Just kidding. You should be fine. There are a lot of people running the calmini bumpers with winches.

One thing, if you end up in mud, be sure to hose out your radiator really good when you get home. #1 cause for overheating of vehicles that wheel is junk in the rad.

You are going to be fine. I thought the winch and bumper were blocking airflow as well. Turned out I had a bad water pump and my timing was advanced too far.

I have this setup and have overheating badly. I have replaced all cooling components and still have overheating. Of course the dealer says bumper and I feel at this point they're right. What I'm trying to figure out now is will a bigger heavy duty radiator help as I've already added two additional electric fans (albeit on the AC condenser). Now I do live in Phoenix and it's bad during the summer, but it is now 70-80 and when I put a strain on the engine at high speeds 60+ my needle shots right up. I noticed this starting before I even had a winch on the front, but now that I do it appears to be even worst.

Has anyone upgraded their radiators for higher capacity and where is a good location to get one?

Gently power wash or garden hose your radiator and condenser. I'd bet your seriously clogged up.

All I did was replace the radiator cap...it was leaking pressure, so the water was able to boil, and that made me over heat when going slow, esp. w/ the AC on.

Got my Rad here Went with the three core and it fits just snug w/o any modifications and it fixed my problem.

Thank you so much for the link. I have just purchaed the 3 row that you did. I have tried everyting for mine. I just did my final modification and it didn't work. I went to Water Wetter and 15% AF and it didn't help.

I was looking at the pictures you posted and I can see why I'm having this problem. I can't believe how cheesy and thin the OE is, it's only 1 row and way to low efficiency.

I can't wait for my replacement. Thanks Again.

Xterras in general tend to have overheating problems - the bumper/winch combo probably doesn't help matters - but it isn't "the" problem.

It's definitely worth upgrading to that 3 row radiator. The stock 1-row stinks.

the 1 row is harder to clog with mud & crap, the 3 row is ~2 times as good at shedding heat.
I have the 3 row, and replaced my fan with an aftermarket one. if you are still having o.h. problems you may want to have the compression checked, could be a bad head gasket..
also change the oil, and tranny fluid(if auto)..
the auto tranny is cooled by the radiator.. if the tranny is making extra heat, it could also cause higher temps.. only other thing is replace the stat.. assuming the pump, clutch fan & rad are ok..
