cause of coolant leak 2000 VW Beetle?
trying to find info for a relative whose car is having issues. check engine
light was on for a few days. The car was low on anti-freeze and she added
more. she drove 45 miles then when arrived at destination coolant leaked a
puddle under the car while it sat for an hour or two. after driving a further
10 miles, car started smoking from the rear, then stalled briefly at a traffic
light. she waited til car cooled down an hour, then added more coolant then
drove another ten miles. traffic was heavy and slow going. during trip, after
another 20 minutes passed, the car was smoking badly from the rear and
smoke started coming through the vents inside the cabin. after parking she
has not driven it in 3 days.
Hose, water pump, radiator etc, Easier to find when the car is warmed up.
I just wanted to get an idea what might be broken so she would know whether to expect it could be an expensive repair or not. Also, she's worried the engine might have been damaged from the car overheating. She's an elderly lady with very small income and worried she may have expensive repairs or need another car. I was hoping to allay her worries about it. At the moment she left the car parked at the house of the relative she was visiting and would already have to be towed 45 miles back to where she lives to be repaired. Since it leaks coolant it can't be driven. Towing so far will already be expensive :(
It is most likely the coolant flange on the side of the engine. its a 4 point connector and it is often the problem part for leaks. They get old and break easy. Part is like 8$ and would recommend a new sensor at the same time which is like 25$ Is about a 1hr to 2 hr job if you know what your doing. this video shows you what to look for and how to do it on your own. https://www.youtube.com/watch?v=Z2Vmn_AwR18
thank you :)
if G12 coolant is mixed with other coolant besides G13 or G12+ the mixture will gel and cause blockages in lines and hoses creating pressure that could cause a leak. if you are switching to green or yellow coolant, the system must be flushed multiple times before switching to avoid premature engine failure and the jellying up of the coolant.
