STERLING STINGER Posted February 11, 2010 Share Posted February 11, 2010 whenever i have the plow on my truck (88) it runs hot....i know, tilt the blade, lower the blade while driving...and this works..but, there has to be a way so my engine runs cooler and i know someone knows in this computer box. thanx again in advanced auto :help: Link to comment Share on other sites More sharing options...
Geonovast Posted February 11, 2010 Share Posted February 11, 2010 Do you have an auxiliary fan already? Another thing you can look into doing is dual electrics and getting rid of the mechanical fan. Link to comment Share on other sites More sharing options...
STERLING STINGER Posted February 11, 2010 Author Share Posted February 11, 2010 yup, i just had to bypass the ?????piece that goes into the radiator that senses the af is getting hot and switches the fan on????? i don't know the name of it :dunno: but my electric fan runs all the time, as soon as i turn my key now.

-600JeepMJ Posted February 11, 2010 Share Posted February 11, 2010 Here is just one of many ways to cool a hot engine. http://gojeep.willyshotrod.com/HowtoBonnetVents.htm Link to comment Share on other sites More sharing options...
STERLING STINGER Posted February 11, 2010 Author Share Posted February 11, 2010 hood vents can't i get another electric motor and rig it into the plow so when i use it, the fan will stay on? or a bigger/double fan?? plus. i just noticed there is a 2" piece coming from my airbox going into the engine mines gone is that important, and wots it dooooooooooooooooooooooooooooooooooo? :shake: Link to comment Share on other sites More sharing options...
Pete M Posted February 11, 2010 Share Posted February 11, 2010 how old is your radiator? Link to comment Share on other sites More sharing options...
STERLING STINGER Posted February 11, 2010 Author Share Posted February 11, 2010 its brand new....i was just reading about thermostats.what is it 195 degree that is stock...what if i got a cooler one...or shave the inside of the cover like i saw on a post...i think cw did it??

Pete M Posted February 11, 2010 Share Posted February 11, 2010 a cooler thermostat will only open sooner. once your truck is up to operating temperature, the system will remain the same since both thermostats will be open (and identical). how hot is it running?

STERLING STINGER Posted February 11, 2010 Author Share Posted February 11, 2010 like i said, its just with my plow on....its almost goes to the red, even with the plow lowered and tipped, on the highway Link to comment Share on other sites More sharing options...
Pete M Posted February 11, 2010 Share Posted February 11, 2010 pusher fan strapped to the grille? :dunno: Link to comment Share on other sites More sharing options...
webbjeepxj Posted February 11, 2010 Share Posted February 11, 2010 I replaced my stock 195 with a 180 and that worked great, as said earlier going any low is waste and doesnt assist as one would think. I really like the Stant Heavy Duty 180 Stat .... its $10ish I think and works well, they make a 160, but it stays open too much and doesnt allow the coolant to "get a rest" before going back into the beast. The other thing that could be done is Flow Kooler water pump. Link to comment Share on other sites More sharing options...
whowey Posted February 12, 2010 Share Posted February 12, 2010 Have you used a water "wetter" yet? I have used it with success on my wheeling Jeep. It will generally run 5-10 degrees cooler even on the hottest summer day. http://www.redlineoil.com/product.aspx?pid=74&pcid=10 There is also a product called super kool or something pretty similar.

STERLING STINGER Posted February 12, 2010 Author Share Posted February 12, 2010 naw...i think i need something stronger than that.... :idea: what about my schroud isnt on over my fan...i know, not safe. but dosent that shroud circulate the air in some way....i mean i know its there for saftey, but is there another purpose for it that might be able to help me? :chillin: Link to comment Share on other sites More sharing options...
Pete M Posted February 12, 2010 Share Posted February 12, 2010 a fan shroud is an important part of the system. Link to comment Share on other sites More sharing options...
CWLONGSHOT Posted February 12, 2010 Share Posted February 12, 2010 I fear your problem is why XJ/MJ's don't make the best plow rigs..... With out redesigning the whole system, its just the way it is..... Its part of my problem as well. Now, I don't have the plow, but I do have a winch that partially blocks the radiator. You say you have a good/new radiator. Is it a 2 or 3 row? How is the fluid? Is it new or no older then last years? How about the mix ratio? 50/50 is about the best balance. A Hi flow, pump, T-Stat and water neck will help. Forget about a stat that opens colder then 180, even that's effects are minimal. How is the Heater core? How about the clutch fan? Oh yea, get a fan shroud!! Its important!! Even with everything working perfectly, if you block the radiator and make the motor work harder, you will have heat build up while restricting the radiators ability to cool it off.

Oizarod115 Posted February 12, 2010 Share Posted February 12, 2010 yes, the fan shroud is more there to direct airflow, without it the fan is able to just blow air around instead of being forced to draw it through the radiator. i agree with CW, nature of the beast. things to make sure of -the new radiator if its 2-core and plastic tanks (you want a 3-core all aluminum piece 1800-radiator has them at a good price) - high flow water pump, thermostat, and housing (one without the others is useless.) - water wetter will help too. -hood vents will relieve some of the trapped hot-air but idk if it will actually cause a reduction in engine temperature.

Icehawk Posted February 12, 2010 Share Posted February 12, 2010 Upgrade the stock clutch fan, a 97-98 zj with the 4.0 and W/O max cooling option has a heavy duty clutch that is a direct bolt on replacement. NAPA part #272310, The standard duty clutch spins 60-70% of shaft speed. The HD spins 70-90% of shaft speed. did it on mine and went from almost going in the red in the summer going up hills to 'never' getting above 215. Makes it kinda sound like a V8 also lol. the problem with going to a high flow pump is it moves the water to fast and doesn't let it exchange the heat out in the rad. thats why gojeep had to add a flow restrictor to get a stable temp. just my 2 cents though.

-600JeepMJ Posted February 12, 2010 Share Posted February 12, 2010 i just noticed there is a 2" piece coming from my airbox going into the engine mines gone is that important, and wots it dooooooooooooooooooooooooooooooooooo? I think you are asking about the preheat hose. it should come from a shroud around your exhaust to your air box. the idea of it is to warm the engine up faster in winter time by puting warm air in the intake. for those of us down here in the South and have know idea what a snow plow is and why you want it on the front of your MJ have long ago pulled it out of our MJ/XJ Link to comment Share on other sites More sharing options...
Wildman Posted February 13, 2010 Share Posted February 13, 2010 I know this sound kind of K.I.S.S.......... But, an easy way to keep your truck from overheating........ Take the Plow off when you don't need it :roll: I take mine off all the time, we don't get snow forecast for a while, the plow comes off. It takes me less than 5 minutes to pull 3 pins, and the electrical connection, and less than 10 minutes to but it back on. Yea, I know, you have the Myers plow, so you have 2 pins, a chain, and 2 quick connects to undo :shake: Plus, you'll see a great improvement in your MPG's after you take the plow off going down the highway at 60 :yes: Link to comment Share on other sites More sharing options...
Eagle Posted February 13, 2010 Share Posted February 13, 2010 I used to run a Meyers plow on my old full-size Cherokee with the 360 V8. I had the same problem. It's pretty fundamental -- engine cooling requires air flow through the radiator, and putting a solid object in front of the radiator doesn't enhance the air flow. I never found a true solution that would allow me to drive around with the plow on as if it weren't there. The only things that helped were keeping the plow as low to the ground as possible when driving, and driving slower. I sold that rig more than 10 years ago so I'm digging deep into the dustbin of memory, but IIRC the critical speed was around 40 MPH. As long as I kept the speed under 40 MPH the temperature stayed under control. Once I went over 40, it overheated. Period, end of discussion.
