Coolent hose routing

[Dave_J]

Ok I have tried to find this on a few other sites but found nothing. I got this jeep with all the hoses off and the overflow tank removed. This is a 90 Cherokee. I think I have it plumbed right but it does not seem to flow right. And it overheats at idle.

Anyone have a picture of what hose goes where.

Are you talking about for the heater hoses?? The rest should be straight foward.

You might have the hose's for the heater control valve flowing in the wrong direction, I have a 91 Cherokee and I cross the heater hose direction causing my engine to over heat at idle Also my heater wasn't heating properly:doh: had to take a second look to get it right, I think the 90 Cherokee just has two outlets my 91 has 4 plus a vacuum line ( for the valve of course) .

PS: oh yeah As a reminder make sure to check the "Heater control valve" for cracks I had purchase one a while back taught I had put the hose on wrong again, turn out the "Heater valve" had a crack in the middle of the seam! ... plastic crap I miss the days when parts where made form metal.
