odd sounds from passanger side

At stop lights my car makes a gurgling sound from the passenger side of the engine compartment also when it does this you can feel the car kinda of shake more than usual but runs fine no misses or backfires. Have any ideas?

Could there be air in the coolant system. check the level when cool. Try adding to up the level and bleed it as needed with the bleed screws.

Okay i bled a little air out of the system but when the coolant started to come out of the valve it came out dribbling and usually its more of a stream. Car has been getting hot a considerable amount of time sooner than it usually does.Can a clogged heater core cause these problems? Gurgling is still there but far less noticable than before.

if its better ,bleed it more.. I changed a heater hose and seemed like it took me 5 times of bleeding.. noise went away and engine ran cooler..

heres what i did when i got this 96 i have now-previous owner overheated it and head gasket integrity went away, slowly at first then creamy oil delight-with the motor cold disconnect both heater hoses at the engine and blow shop air first one direction then the other. i run my shop compressor (2 stage) at 160 psi and didnt blow the core up but i have been wrenching far longer than i care to admit to myself and kind of let some pressure thru my fingers as i did it. to paraphrase-use common sense and dont blow yer core to smithereens-aim whatever hose happens to be doing duty as the outlet away from the family jewels, eyeballs, yo mamma and anything else you want to keep nice. you will scratchin your head as to how much ca-ca could actually be in there. i think i found a chunk o' jimmy hoffa in mine.
