Postby runkillerrabbit » Thu Feb 21, 2013 12:12 am

im using the t3 reroute for my black top conversion. i finally got it running with aem ems-4 standalone. but now the water wont circulate!

Run until it hits operating temp, then the thermostat should open and water should circulate. If it doesn't, remove the thermostat and try again, water should circulate freely with this arrangement.

thermostat is out so i can check circulations. so the water should be flowing.

Waterpumps, especially really loose ones like automotive stuff, can't pull at all but sure can push.
Is the radiators lower outlet going to the pump inlet?

i have installed exactly like this. except that the hose goes over the alt. im gunna try adjusting the hose so it it flows down from the radiator. not up. would that matter? would an air bubble in the engine cause this?

if i cant solve this i gotta pull a completly tuned standalone black top PLEASE HELP!!!

You can't run water from the top of the radiator. Any vapour produced in the system gathers in the top, that's why the overflow connects there. If you try pulling from the top you will pull air into the engine. Remember, always push to the top and pull from the bottom of a radiator.

It could very well be air in the system, but I would still expect at least minimal circulation.

Give T3 a call, number is 530-626-7334, guys there are really good to talk to and will be able to help with your problem.

I discussed it with a mechanic friend of mine, and he's wondering whether or not you removed the rad cap when you tried to flow it. The bypass will not relieve any significant air in the system, you have to pop the rad cap (cold of course) and let it out while it runs.

Radiator clogged? If the lower hose is removed when full & cap off, there will be a stream the size of the outlet shooting out over 1/2 a foot that will drain it in seconds.

some open pumps need to be "primed" ( have water in the rotor area). so today imma guna force water in with a hose while the front end is jackced up.

see if that works.


this is only thing left.

There's nothing to force unless the thermostat is air tight or the rad. is lower then the pump. You got neither, but you do have a potential air lock from that pipe.
If that upper outlet line gets filled first, the lower line that is filling the block & pump &head won't be able to push any air through it.
Can you fill it with the upper on the back of the head loosened to let the air bleed out back there?

You won't get coolant circulation in the radiator until the thermostat is open.
It looks like the T3 kit puts the thermostat on the coolant outlet which is reverse to the OEM setup.
The Garage Annex kit did the same as far as I can make out.
When the thermostat opens you should feel the upper pipe get hot and see circulation when you look into the rad neck.

Look at it from a process perspective, the force that circulates the water is the pump. If the water does not circulate, it means the pump is not working or the back pressure on the pump meets or exceeds the output pressure of the pump, or conversely that the pressure before the pump is insufficient to eliminate cavitation and the pump will not produce enough pressure to circulate the water significantly. The latter is a lack of head pressure.

Therefore, we have three possibilities
1: The system has a clog in it either before or after the pump, since you checked your hoses I think it's in your radiator.
2: The pump is damaged, unlikely since apparently it's new
3: There is a mass of air prior to the pump creating insufficient head pressure on the pump. This is very unlikely, further I would expect that this would sort itself out from previous attempts.

My best guess is that there's something in your radiator.

Mishimoto is pretty high quality, if it's plugged it can probably be fixed. If it turns out the rad is the problem Mishi offers lifetime warranty on their products

really sorry for the late update. but it was not a plugged radiator.
when i pulled the engine. and drained the oil there was a bit of water mixed in with the oil.
possibly a bad head gasket?


couldnt figure it out. and my blue top 16 valve rebuild was complete.

so i pulled the black top and installled the blue top.


ill be doing the jsp water reroute my self.

Sounds like you have to tear down the engine again and inspect all your ports. Sorry to hear it's been such a pain in the ass

Well I'm not sure how much help I've been, but I wish you the best getting your problem sorted out. We all love our 86's here, and for me at least I always feel bad for the guys who can't get their ride sorted out. Mine hasn't been on the road in over a year so I know your pain.

As a note though when it does hit the road It's going to be incredibly different, it's an SR5 we converted to GTS then dropped a silvertop into (prefer blacktop for ease of install but we got a killer deal on this one). Sadly no new struts or wheels, but I'm still excited

I'd try to really be sure that it wasn't just from condensation. It's had lots of startups with short run time hasn't it?
////
I'm more interested in the circulation, ever figure out if the pump was getting primed, getting a free flow from the radiator to it with no air lock??
They'll probably only pull an inch or so of head pressure, while their output will be 50 times that.
