coolant overflowing...........

i've got a 88 cherokee and yesterday i shut it off and when i came back there was coolant all over the street. so i thought i overheated and didn't realize it. so i checked the gauge. not overheating. so i filled it back up and drove around for about an hour with no problems. temp. stayed around 210. shut it off and it started to pour out again all over the street. so i do know two things 1) it's not overheating. 2) it only overflows when it is shut down. i was thinking maybe head gasket, maybe sucking in air and creating a build up? but my friend says he thinks it's my coolant resevior cap seal. so first i'm going to buy a cap because it's cheaper and it can't hurt to try. but i would appreciate any help or advice from anyone.

thanx jerry

p.s. i checked all the hoses for a blockage. nope. and the overflow is coming out of the large hose at the bottom of the radiator, not from the overflow tank.

Mine did the same thing and after swapping the fan clutch still did it...it turns ou thtere was still air in the system and was adding unneeded pressure. When the system would "burp" the air out, it would also send coolant out with it...make sure you have no air in the system. It may save you $$ on a water pump.
