MY coolant appears to be missing ?? LOL when the heater on the inside is turned onto auto it overheats ..... The a/c appears to over heat it as well ... Its only sporadic tho and not all the time ,,, I have had the rad , condenser fan , thermostat replaced about 8 mths ago and it came to a stop . and now it appears to be happening again . what do you think .. Also sounds like water swoshing under the dash at times .. Help what is the cause or causes
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.

Coolant leaking from deicer under the throttle body. Technician at Big Al's tried to diagnose as a coolant pump failure.
Dealer diagnosed problem. Recommended I replace radiator as well. Second time at dealer for coolant leak repair work. In total, about $3000 fix.
