Overheating Issues, Perplexed

[undy]

Good to hear El... It sure sounds as if you've got it knocked down now.

I bought the Hollister relay setup with both temp sensors, 180 and 195. I'm out of bungs on my tunnel wedge intake for the 2nd temp sensor so I'm going to drill a hole in the bottom of my expansion tank and silver solder a new bung in there for the second sensor (195). It'll be hidden since it's in the bottom of the tank. I'm also hoping I don't generate any unwanted electrolytic action by doing this, time will tell. (looking for opinions on this too)I prefer to have both high and low speeds to work in auto. I'll also run a toggle for high speed.

I was properly shrouded before so I think it's more of a CFM thing, more-so than the shroud .... at least in my case. You also have a larger radiator than the Lone Star has, 27" wide vs 22", so you're probably not as "cooling challenged" as I am. I do have the 1 1/4" tubes vs the "normal" 1" tubes so that helps. I’m really looking forward to doing my conversion ...

I too would prefer the high circuit be on an auto switch as well. I may just sh*%-can my heater plumbing and use that manifold hole. It not like I need a heater in Houston in a car with no top.

Although you are a little limited to sensor locations or accurate pick up points the heater pick up points are many. You can get creative with T's and parallel lines since all you want is hot coolant.

A side note from earlier post, remember to add anti-rust or corrosion additives to eliminate electrolysis problems and get seal/lube agents.

Jim;

Don't you just love it when a plan comes together!!!!!!!!!!!!!!!

Man, I'm glad it all worked out, there is nothing worse than going for a drive and having to constantly watch the temp gauge and wonder when will it overheat again.............

I'd be willing to bet on high speed, you could let that thing idle all day long and be o-k temp wise, now, you need to go do a parade and show off the car.

PS: Now that it's all working properly, I'd add some rust inhibitor/lubricant like Prestone and maybe a half gallon of anti-freeze.... Can't hurt and will slow down corrosion inside the block..

Don't do that -- just use a tube in the bottom of your lower radiator hose with the sensor welded in to it. It works very well and it's another job you can do largely while sitting at the kitchen table. Here's a shot of mine:

Its 95*F out now and I just let it sit idling in the driveway for 30 minutes and it stayed at 195 with the fan on low and between 185-190 with the fan on high. I have not added anything to the water yet, but plan to this eve.

Yep, that's exactly how my primary sensor is installed in the upper hose. I was trying to avoid having another one of those in the system but I guess it really doesn't matter, its hidden down below anyway.

Jim, glad you've got it solved. Please post some pics of the install. I may well go that route as well.

Hi Matt. Its an awesome fan. I ran around again this evening and it was 185*-190* all the way ground pouding around the 'burbs, and 180* down the road. This coming weekend I plan to remove it, trim the shroud a bit and engineer some permanent mounts using the 4 existing through-bolts from the Hurricane fan. I'll post up pics over on this Taurus fan thread when I am done.

I highly recommend it for the Hurricane.
