New and need help

[iamdolfan1]

My 1991 xlt explorer sounds like a coffee pot percolating when it warms up. Replaced heater core,thermostat, water pump, radiator, but still makes noise. Must relieve pressure at radiator when I shut it off or it really bangs loud and won't stop until it cools down.




Anyone have a solution to my issue?

Make sure you have the right radiator cap and you've "burped" all of the air out of the system.

Welcome to this forum! Did you check the coolant level? How many pounds is your radiator cap?

" Help" truck still perolates

I replaced the radiator cap (13lbs.) and "burped" all of the air out of the system and it still percolates. But it only makes that noise when I have the temp. control to the heater on hot. If I set the temp. control on half way or lower it doesn't perk.

..first get some maxwell house and some filters next get ... i kid ....


....have you tried burping the system with the truck aimed up a slight hill and the heater control set to hot so coolant is not diverted and gets into every area of the system with the proper mix ?
