Title: Radiator in back?
Post by: Boggen Joe on January 17, 2012, 11:39:19 PM
Is it really worth putting the radiator in the rear of a bogger? I've seen a lot of TGW trucks both ways, some say it helped n some don't. So I'm trying to decide if I should put my new howe rad in the back of my k5 or not!
Looking for info from y'all thanks

it stays safer and cleaner in the back. it also can help cooling by moving it away from the motors heat..  mines in the back and it works good. and I would do it in every mud truck I have from now on!

How can you say its safer?  its not a truck with the back of the cab.  its a blazer. radiator is in the same place as you. and it is coverd not open to the air.

I ment safer for the radiator..  I ran my mine in my old cj5 right behind my head.. if I did it again I would use lexan to shield it..

he was asking about mounting inside a K5 which is an inclosed area, not much air moves thru the passanger compartment which will make it overheat , and if it boils over where is it going? all over the occupants,

how well are you guys keeping cool? trying to decide if i want the radiator in the back of my pick up with a 454. I dont know if i t will stay cool enough. I plan to bog it and do some slow speed crawling. just wondering how often you guys have to sut down becasue its getting too hot.

I went by trial and error lol  ended up just mounting a couple of elec. fans on rad. in back and have never had a over heating issue and never have to shut down.  but as long as your moving you should be alright but going slow or crawling or trails youll probably run hot. fans are easy to install and I just wired mine to toggles and just keep an eye on temp gauge.

I like the fact that you would be adding a couple more gallons to the system,  with that being said is there any loss in pressure in the cooling system?  Do you run a thermostat or run open flow?

no loss in pressure in system unless there is a leak,  remember the pressure is not created from the pump it is from the heat,  I run open since most my time running is in summer and Have no need for heat,  I also run a heavy duty pump, probably not necessary  but I figure I'm pushing more fluid and had it laying around.

I used 1 1/2 and 1 3/4 inch exhaust pipe on mine also use stock water pump. use a restricter washer instead of a thermostat,always flowing. also run a Howe radiator with 1 16" fan. Up at Rocks and Valleys it runs about 170-180 degrees on a 45 minute trail.run a seperate trans cooler in front of rad. it runs less than 150 degrees on the 45 minute trail.i also installed a cover over the radiater and get very little mud in the fins.

it will be fine there is alot of air in there... mine was mounted in the back of my s10 blazer no issues...you can build a shield for it  also to cover your drivers compartment from over spray

I put my Rad in the bed because it was constantly getting plugged with mud. I used 1 1/4 Copper with 45 deg bends, stock rad hose to connect to the motor and the rad. Stock water pump. I also use a suder duty trans cooler and a fan out of a Fusion. The only issue I had was burning up switches to the fan, but once i installed a relay I haven't had an issue. Can run hard on the hottest days without any issues.

I like the copper idea since copper disperses heat  but its  no freakin expensive

i'm definately putting my radiator in the back. My buds that have em don't even need to turn the electric fan on half the time and they run stock pumps and stock 2 core and 3 core radiators.
Title: Re: Radiator in back?
Post by: BAD APPLE on January 18, 2012, 11:06:58 PM
most run them in the back because they run 2 radiators, thats what we do in our trucks, plus the longer the coolent is out of the truck while circulating the better it cools which in turn the longer you can run with out over heating, with two radiators with a built big block i have never had it over 190 degrees temp
Title: Re: Radiator in back?
Post by: michigan maniac on January 19, 2012, 01:57:55 AM
How do you run your hoses for 2 radiators?  Lower hose from radiator 1, to upper inlet on radiator 2 ?
Title: Re: Radiator in back?
Post by: BAD APPLE on January 19, 2012, 03:12:00 AM
well you have the two places that the front radiation go on the thermostate housing and the other on the water pump where it normally goes then there are a couple other smaller bungs on the water pump to plumb into

sounds goofy,

I ran lower hose to pump, upper hose went to rad in back and out of there to therm. housing. there is all different ways to run it just depends on what works best for you and your vehicle. Idk about running it on the extra hook ups on water pump they are usually pretty small like 1/2'' or 3/4''  and goes to heater core, I would imagine there would be a massive loss of flow trying to get it thru  that small of a hole to circulate the rear rad. but Idk  jmo :)

The two other spots on the water pump are where the heater hoses run too I believe someone correct me if I'm wrong

yea thats what im talking about, where the heater hoses would go to heater core, Is that how yours is hooked up?  if so do you have any flow problems? just wonderin
Title: Re: Radiator in back?
Post by: michigan maniac on January 19, 2012, 04:40:17 AM
I don't think you would have any flow problems, you may have slightly less flow than bigger hoses ( obviously)   in all reality you could run your heater core outside the cab like in the bed to displace more heat, that's if you don't care about having heat in the cab, all a heater core is a small radiator ..

Post by: MR NASTY on January 19, 2012, 04:54:34 AM
I would recomend using as much hard pipe and as little rubber hose as possible in a enclosed compartment. And people don't blow radiator hose cause they are new its because they are old and should have been replaced long before. I'm gonna relocate mine to they back of my jeep and with these methods in mind I'm very confident there will be no issues.

My truck ran between 200 and 210. idle or full throttle, as long as the fan was on.  without the shroud and fan 15 minutes is all it takes to get hot.  I used 1 1/4 exhaust pipe and a 12" electric fan on an aluminum 4 core radiator and a factory mechanical pump for an sbc.

Post by: BAD APPLE on January 19, 2012, 02:01:07 PM
The smaller hose will slow down the flow but that can be a good thing the longer you can keep the coolant in the radiator the better its gunna keep cool , I even have a small slug in the hose with a hole drilled in the slug to restrict it even more, we run hose full length, we use regular heater hose never had to replace it going on 5 years with it. And I run a big block no problems over heating at all and it gets beat on, I have never had it over 190 degrees running temp

I put my radiator in the back of my cherokee, its right behind my seat with two elec fans and a 160 thermostat. I do jot at this time have a sheild ob it but am going to put obe in soon. It does get warm inside the rig but i took the rear window out for ventilation. I also run an electric pump... puts out something like 44 gpm.

here is how i ran my two radiators, your original front one hookes up like normal, top hose to the thermostat housing, and bottom to the water pump, now with a rear radiator, there is a taped hole next to the thermostat, i threaded a bung and hooked one hose for the rear radiator there and then there is a bung on the water pumo that i ran the other hose two,  then i used 1in heater hose and ran that down inside the frame rails to keep them from getting punchered, and drilled to wholes thru the floor and ran the hoses up into the back of the bronco to my second radiator

i got a question. why dont you just run your lower and upper hose to the back to a radiator and put a fan on it. that is how i did mine and i never had a problem. I used a stock pump and a two sticks of 1 1/2 muffler pipe and never had one problem. hell my s 10 never went above 180 with the fans on.

Every engine cools different I had a stock small block in my bronco once and I couldn't run 5 minutes with out overheating buddies got a built big block in his truck only runs one radiator, never over heats, just gotta find the right set up for what you have and how much you beat on it
