Hey guys. In preparation for the hot days of summer, I figured I would do a little PM on my Pred to keep it from overheating. As it stands right now, the fan stays on constantly when riding tech trails. I ordered some Engine Ice online and some inline coolers off of e-bay and installed them last weekend only to find out that I am not sure if it helped as much as I hoped. At first after some long idling, the fan never came on. I took it out to some quick trails behind the house and it seems as if the fan stays on like it always has. I did have a little trouble purging all of the air out of the cooling system at first. I didn’t get all the air out until my last ride so I am not sure if that may have played a part. I did not expect very much from the coolers I got but I figure that every little bit helps. One on each hose. They are one of those 20 fin ones. I guess it would help if I had a temp gauge and I could actually see the results instead of trying to hear them. If anyone has any suggestions, I am all ears.

It seems the engine ice's purpose is to pull more heat out of the engine, and if that is the case, the fan would run the same as before, if not more than normal, due to the EI pulling out more heat. But that would be offset (you would think) by the fins on the hose. Just my 2 cents. If you do get a temp guage, keep us posted on what you find out.

I just got the red line water wetter, modquad did a test on it and engine ice, and the water wetter was better.

 

Thanks for the mention Raj. [img]i/expressions/face-icon-small-smile.gif[/img] Redline's Water Wetter did actually test better. We had some slight "foaming" problems with the Royal Purple product. Engine Ice helped, but not even close to the Redline results(but Engine Ice has anti-freeze capabilities). The inline coolers did remove around 9 degrees each. In the end, we replaced one of them with Eddie Sander's Racing billet temp gauge....that gem works flawlessly to this day. Full results can be found on pg 76 in the Nov. 2003 issue of ATV Sport. Yes, you can order old copies. [img]i/expressions/face-icon-small-smile.gif[/img] Don't forget, your temp sending unit on the top LH side of the engine works great to "purge" trapped air. Also, the bottom water-pump cover bolt is the engine coolant drain. Flush multiple times with distilled water, and ONLY use distilled water while mixing your coolant "blood".

at what temp. does the overheat idiot light come on at? and who sells this temp guage you are talking about?

i found the guage. 80 clams, is it worth that?

 

Hot light on - 221*F
Fan on - 180*F +/- 7*
Fan off - 150*F +/- 8*

Thanks Chris

 

I switched over to Engine Ice and have yet to have my fan kick on but once since then. Is there a way to tell if my fan is crapped out on me?? An easy way like crossing some wires is what I am looking for.
Thanks

 

I had the same problem when I had my Scrambler, I was using engine ice and the fan would never kick on. You can unplug the fan and tale a battery charger and look to it, to make sure the fan still works, I done that a few times.

 

I will make sure that I have no trapped air in the system this time before I ride again and monitor the results. From looking at the specs of the cooling system, it looks as if it would purge the air out on it’s own but I guess not.
