It sounds like the water pump but check your lower radiator hose clamp it may be loose.
Just because there is a leak doesn't mean it will overheat instantly, but if you do not keep adding coolant or fix the leak you will have engine problem
It could be symptomatic of a larger problem. The coolant may not be circulating properly, or the indicator panel or car's computer could be developing trouble.
I have the same van It is perfect, but I think the problem that makes it overheat is either not enough coolant or a clog in the coolant tubes. Take it to a mechanic and sask them to check that out for you.
radiator plugged.or coolant low
No, if anything it would get cooler from having too much. -You have a different problem, possibly a coolant leak.
check the water pump
It probably means that there is a leak or a blockage. There is a good chance that the engine will overheat and seize-up. Get the problem repaired immediately.
Did your car overheat? That's probably why it turned off if it did. If you are losing coolant, you should find out where it's going and fix the problem.
Broken radiator fan/fan belt. You coolant level might also be low in addition to the fan problem.
As with any car, low coolant will cause this car to overheat. Common areas of coolant lose are the water pump or intake manifold gaskets. If the coolant is full, then another common problem is blown headgaskets- especially the rear head. A blown headgasket introduced compression into the cooling system causing air pocket / bubbles. This will cause an overheat.- TechJK -----------------------------------------------------------
If there's no leak, an overheat is caused by a problem with coolant level, coolant circulation, or heat transfer. Fill the coolant level. If the problem recurs within a month, it was something other than low level. Circulation problems are caused by clogged radiators, bad water pumps, non-functioning thermostats.
