can anyone draw me up how to route the heater hose lines using the stock over flor box or is there a way to customize it? im trying to put a jeep together someone elso tore apart so its a little tricky and im to cheap to buy a manual

 

this is what i came up with any body done anything differant? that cheap stock over flow box sucks its cracked and there hard to find. Any one tried just running it direct to the heater core? seems like it would make to much pressure.

 

You can download a parts manual, http://www.xjjeeps.com/tech_referenc...section=2&ID=0
page 1009 shows the heater hoses and each hose has a description where it goes. Your gonna need to replace that coolant tank if it's cracked, your radiator will never build pressure like it's supposed to.

 

do you see anything wrong with the way ive got it runnung right now?

 

Here is a photo of my stock 1989 Wagoneer coolant lines setup.

 

so the line coming off the top of the tank Ts into the same line the valve is on?

 

Yes, here is another view.

 

I have ran itthe same way just dont have that valve in there. It over heats and the over flow tank looks like its gonna blow up. Ive tried a new thermostat 160 degree still over heats. Now im gonna go to napa and get the valve cant see that making a differance but guess ill try. Got any ideas?

 

never mind traped air in the system got her goin now runs to cool thanks to the new 160 degree thermo

 

Solutions:

1) Last I looked, you can still get the replacement tank (with cap) from Morris 4x4 Center (Google them - I don't recall the URL at the moment) for about $25 or so. The tank is good for 10 years' service, tops, as far as I'm concerned.

1a) Mac's Radiator (www.macsradiator.com, I think) has a replacement metal tank that takes standard caps. But, it's spendy.

2) See the attached picture for my solution to the heater hoses. I've been running that for years without incident. (The valve is a backflush valve, the fitting sticking up is a hose bibb adapter for system flushing. The heater valve was deleted with no ill effects.)

3) To prevent entrapped air, drill two holes in the thermostat flange, about 1/8", 180* apart. Install with one hole at 12:00 and the other at 6:00, and the system will purge itself of air.

 

lol my readneck loop lol but i had no heat at that moment i'll get picks of my setup on mine

 

yes the holes in the thermo is a must both my jeeps have ran me for a loop over heating and all both times ive take the thermo out and no water in the head.

 

is your water pump goin?
take a pic of what you have right now

I was wondering about that also. They must mean drilling a couple of holes through the flange of the thermostat before you install it in the housing. That way it wouldn't seal off all the way and have those small holes to vent.
