Well the summer is here in Indiana and this will be the first year my jeep has been running in the hot months for close to 25 years.
I just know the thing will overheat. I have a very thin 2 core in front of the mild mannered 305, I cant go anythicker due to clearance issues.
My question involves the use of and electric water pump. I know summit sells them for not that much. I was wondering if anyone had any experience with these on the trail. How do they compare to a normal pump.
IF the electric pump gives me more clearance I could go for a 4 core extreme duty radiator from summit also.
So my options are..4 core w/ electric pump
Or chitty 2 core(from a sunfire) with a normal pump.
I am currently running a high$$ 16 inch push fan. I would like to make it a pull but this set up did keep it cool all winter.
Any othr tips for cooling im sure could be found in a search but feel free to enlighten a newbie on some tricks of the trade.
Yes...At least I am pretty sure. IT came out a a 79 Monte.
From looking at the summit pumps they look about the same size minus the pully/fan mount. Looks like I could gain a couple of inches. I figure a couplde of inches could be a couple of rows.
I just want to know if the electric pump is worth the money.
from what i know i don't think the electric is the way to go.designed for 12 second romps down the quarter not continous.pretty sure you don't have the short pump,MUCH shorter than a standard pump.call summit up they should be able to get it for you.came on 60's vettes originally i think.i have one on a 283 in the garage and also put button head allen bolts on the pulley for more clearance(had it in a 2wd toy at one time).i was also able to use an electric puller fan with the extra clearance.
I figured I could make some different belts work if I went with the electric pump but I was concerend about how much money would be involved in getting all my pulleys to line up with a shorter pump.
Also I was looking at a circle track pump, not a dragster pump.
When you went with the short pump what did you do to get it all to line up.
Tell me what you all think of this plan of attack.
One Summit 30% more flow short stlye water pump(62.99)
One summit alternator aaccesories universal alternator arm for short style pump.(13.99)
One summit extreme duty aluminum rad(169.95)
Fab my own power steering bracket.
New belts.
All in all I would come in under 300 bones..is there anybody who thinks this set up would not keep a bone stock(minus all that chrome of course) 305 cool using a nice 16 inch electric fan...hopefully as a puller..possible as a pusher
That should work. I live in Phoenix AZ and we get a little hotter that you guys up north. YES, we really do, even though you think we don't. A good radiator is the trick. A high volume water pump isn't a bad idea, it will help keep away hot pockets and such. The main thing is to have a good radiator and you will be fine.
You are on; I used to live in Minnesota and went fishing in northern Canada on a regular basis. I love the cold weather. I would love to go wheeling with you in the middle of the winter.
I know it is a dry heat here in Arizona, but so is my oven and you don’t see me climbing in there. I lived in Minnesota with 90 degrees with 90% humidity. Nothing like 122 degrees with 10% humidity, Sorry.
I would invite you to go wheeling here in the summer time.
avoid the electric pump.......... I guy I know has one in a flatfender
running a mild 327....... it overheats ALOT.......all the time........
it sucks to be in a group run with it.....
--run a chevy short pump, almost no spacer, and a mechanical
fan..... or try a clutch-fan....... avoid flex fans, they are for more
power at high speeds....
I had a 95 Chevy Caprice (Police Package) with the LT1. When I bought it in July it would always overheat. First thing I did was make sure that both of my electric fans were working properly, no real difference, cause the computer kicked on the second fan at 205*. Turning on the AC caused the second fan to automatically come one which helped some.
Then I replaced the water pump with an electric Meizere (sp?) one. It did make a difference, but the fuse went once on me and before I knew it the temp was way up there.
As for clearance, the electric pump mounted on the front of the existing water pump. Basically you pressed out the original impellor and mounted the new electric to the front and through the old hole for the impellor shaft. It ended up being much much closer to the radiator than the original mechanical one.
I'm planning on going this route. The important thing is to make sure the unit is designed for continous use (in other words the circle track version, not the dragstrip version). Next get rid of the thermostat, simply run the electric pump through a thermostat relay to come on at a certain temp (180 - 190) and go off at a certain temp (160-170), depending on your application. The electric fan works the same way, on at a certain temp, off at another.
The nice thing about this set up is that if you hook it right, the water pump and fan will be cooling the engine even when the engine is not running.
You could even get a remote mounted electric water pump; they are more expensive, but you'd get a heck of alot more room between the engine and radiator.
