overheating is back

[VX KAT]

I'll give that a try. Same with me Sue, doesn't overheat when the A/C isn't running. Thanks for the tips.

I'm going to try the pressure washer for sure, I see all kinds of bugs and brown crap on mine. Guess I can just blast it straight on?

What about your fan blades Greg, are they way into the shroud or do they break the plane by some distance?

This was October of last year on my long road trip...but it pretty much looks the same now....does this seem to be a lot of crude?

Sue, it's what you can't see buried in the rad fins that can cause all the hub-bub. If you hook-up a garden hose to your water heater so you get HOT water and blast out all the crud from the engine side of the rad, cleaning the entire rad side to side and top to bottom, that should certainly help. Put a nozzle on the hose end so you get a hot, high-pressure stream! Best of luck and don't scald yourself!!

But use caution to not bend the fins.

Good point! If you do have alot of bent fins, you can straighten them using a tool called a fin comb available at any HVAC supply store. (Heating, ventilation and air conditioning.)

Trying to find out if my fan blades are positioned more forward into the shroud than other VXs.
Kirk, how's this compare to yours?
Anybody have any comparisons, thoughts or input??
****************************
These two shots are straight on of the shroud & fan blades.
It seems like the base of the blades are actually further rearward than the tips of the blades









From passenger side, can see the one blade sticking out:




Dave's holding a ruler flush against the blades so it's easier to see how far they clear the shroud






Distance/gap is about 1/2", if that.



I know it's a totally different engine, etc...and it could be apples to oranges, but on both the GX and Dave's FJ, the blades stick out at least 1 1/4" outside the shroud:

.Just thought of a question... the pics of the FFD 17" fan set-up show it has the fan blades completely within the shroud.....so how does that improve air volume???

My opinion is that the cooling system worked at one point in time. If it is no longer getting the job done, there is something in the system broke, clogged, etc that is preventing the system from working properly. There should be no "need" for custom fans and radiators...not that they are not nice and sometimes effective. Unfortunately finding the "broken" part can sometimes be a pita.

Think I found the culprit. A/C is spinning sllllllllllllllllllllllllllllllllllllllllllllllooo oooooooooooooooooooooooooowwwwwwwwwwwwwwwwwwwlllll llllllllllllllllllllyyyyyyyyyyyyyyyyyyyy. I'll be replacing that next week. Still wanting to chop up my hood, though

How'd this work out for you?
