Yes but when car loose water problem is already there.This is not normal HG issue from age or use.This is engine design flaw and manufacturer did address problem modifying engines later.So there is nothing you could do when problem starts.My friend did buy Toyota for its reliability and got nothing but troubles.I'm not bashing Toyota there was other high tec diesels with problems like VAG 2.0 tdi (injectors) and Ford Puma 2.2 diesel that burned a hole thru piston on my van at 100k.leaky injector).
