Oh yeah, half a dozen US retailers carry the DC0500, I think I got mine from Summit Racing. My 00 I have set to have the first fan come on at 185 and the 2nd one at 190. Local climate and year model might make a bit of difference. Monitoring not super important as long as you have something different to monitor engine temp, I just like having old school gauges better than ultragauge, I do like being able to see when the fans are on versus off. I ran a manual fan controller for a while and if there was an issue I did not know until the temp was higher than I liked.. That Amazon unit should work, are you planning to wire to turn both fans on at the same time or use the sequenced operation?

 

Curse you smart people that continue to make the list longer and longer. Methinks the Giverny will be my personal test bed for this as I get it going (assuming I don’t need to pull and fully rebuild the engine).

My anecdotal evidence of how great an idea this is (not to mention the fact that it has been designed as a plug and play kit) is from my ‘95 Jeep YJ. This was 20 years ago, but back then, the hot setup was to go with a Ford Taurus fan and a big honkin relay and all that. I did a temp sensor through a few fins of the radiator and hooked it to a 3 way switch (the temp sensor was not variable as I think is in the Extinct design) so I could have: 1- on all the time, 2- on based on the temp sensor, and 3- off (for deep water crossings).

Keep in mind the YJ is a tin can and the 4 banger I had in it was rated at like 115 hp out of the box. My butt dyno said there was a definite improvement. Throttle response was better and it just seemed smoother altogether. Also, it showed just how tiny an engine that 4 banger was as there were miles between the radiator and the front of the engine.

The only downside I found in my design was that there were times I forgot to turn the fan back on after a water crossing (I don’t use my Discos like I do my Jeeps, so not an issue for me) and until I saw the temp creeping up, it almost caught me out. Again, since i don’t use my Discos for hard core stuff and Extinct’s design allows for you to set the temps up for set it and forget, this is perfect. Since I’m too busy to design my own deal, it’s worth it just to get a plug and play deal like this.

To make my usual Saturday morning coffee induced ramblings succinct: Well done!!!

 

One interesting thing I'm learning, if using an Inline Thermostat, it seems it may be possible to consolidate two separate coolant and radiator monitors into one. DC makes a 1/4in NPT threaded coolant sensor (part #DC-0465) which can be combined with the DC-0500, rather than using the DC-0500's radiator fin thermometer.

So...Inline Thermostat with Port Up sensor port + 3/8" to 1/4" adapter + DC-0465 + DC-0500...and I believe you'd have a pretty clean solution that would avoid needing two separate monitors.

The DC-0500 even has an alarm functionality, so you wouldn't lose that.

This would save me about $20 from no longer needing the GlowShift coolant gauge I was going to go with.

Combine this all with an electric water pump (DC's EWP115), and maybe I could delete yet another belt-driven component. That would be fascinating.

 

This is my next mod after I get the new engine all sorted and broken in.

 

@CharminULTRA Good point, I installed the same sensor in the thermostat housing, will update all information to reflect that. Cleanest install.

 

@Extinct are there any upgrades I need to make to the electrical system? Like a beefier alternator, etc.? Or should all stock be fine?

 

All stock will be just fine if you use the recommended fans, they only pull about 5 amps.

 

Nice, thank you!
