Also sounds like water swoshing under the dash at times .. Help what is the cause or causes
Coolant leak throttle body have not fixed yet why does it leak
Throttle body leaked coolant, so I bypassed it by pulling off those little hoses and joining them together with copper tubing and hose clamps. This heater is not necessary and is overkill, 'cos even -25 F below zero won't freeze a throttle. I've driven cars and trucks in winter for 30 years and never seen a frozen throttle.
