I/C Pump Flow & Hoses?

James Thomas

"NO CLASS"
This is gonna be long, maybe crazy and require actual thought process so I will beg forgiveness now. I have searched, found instructions and even a diagram but it does not make since to me so please help me out here or just shoot me and get it over with.

In doing the high flow I/C pump and rubber hose swap it says that the lower I/C hose goes to the pump and the upper hose goes to the CCH. This would make the upper hose suction from the I/C to the CCH and the lower I/C hose discharge into the I/C according to: http://www.sytyarchives.com/howto/v...name=metal_ic_line_replacement.php&dir=engine

On my Ty, in stock configuration ? the the lower hose was routed to the metal line under the T/B that crosses the front of the intake under the Alt. and went to the CCH core and the upper hose went to the metal line over the back of the intake to the pump. Which one is correct? Has some one mixed up the hoses before I got the Ty?

If I follow the instructions in SyTy Archives and run the hoses over the top of the I/C, correct me if I am wrong but won't that create a air lock condition with the hoses higher than the filler neck? Also if the pump suction is from the upper hose won't it suck air if there is any (I mean any!) air in the top of the I/C? Shouldn't the suction be from the bottom of the I/C where there is no air pocket and the return dump in from the top hose?

In my way of thinking (Oh brother here I go!) the pump flow should be suction from the lower I/C hose to the upper left CCH connection, through the CCH and out the lower right CCH connection to the suction inlet of the pump and pressure flow to the upper I/C hose inlet to avoid sucking any air...... right?

Does any of this make any difference or am I just nuts :rotf: ?

Re: I/C Pump Flow & Hoses?

Well, none of the sytyarchives how-to's seem to be working this morning. However, I think you are correct, and your Ty was plumbed correctly. The system will purge air better when coolant flows out of the pump into the upper IC thru the top nipple, and flows out of the upper IC to the CCHE via the lower nipple.
