Own and drive a 1995 G- Cherokee Laredo and every time I start the engine, I hear this sloshing sound on the front passenger side.Checked underneath the passenger side dash or carpet and it's not damp or no evidence of fluids.Checked my coolant reservoir which is also located aligned with the passenger side from the engine bay and there is no evidence of leaks. The sloshing sound disappears after about 20 minutes when the engine gets warm. My first Jeep and wondering if anybody else who have the same model have experienced this?

 

Welcome to the site, that is almost guaranteed a sign of low coolant. When cool.. Check the level in your Rad, I can bet it is low. Mine did that all the time before I put a new Rad in.

 

Thanks for the info Kazman, appreciate your time in sharing your experience. Going to check it as soon as possible and maybe the radiator is going bad.Thanks again.

 

I have a 99 Cherokee Limited with the same sloshing issue. Did you folks find the solution?

 

What you're hearing is air in the heater core. Make sure the hose from the thermostat housing is going into the bottom pipe on the heater. This will bleed the air out naturally.
