SOURCE: Dodge Caravan 1990 coolant leak..

do not put water in your radiator. Use 50% mix of antifreeze and water or you will corrode your engine. Add coolant mix to cold engine. Fill the reservoir and the radiator. Warm up eninge while looking for the source of the leak. If lucky, it will be the lower radiator hose. Easy repair. If it's the engine block, big problem. Let us know what you find.

The drain is located on the passenger side of the radiator at the bottom. Turn it counterclockwise to open. It is plastic so be careful if you decide to use tools to turn.

Yes, it could be a few issues, I always believe to go the cheapest route first, so you are not just replacing parts to be replacing, Based on your description, Normally it would not be overflowing if your pump is not working, It could be a clogged hose, you would have to flush system to see if that was the case, but based on my feeling, i believe it is a stuck thermostat, If your tank is overflowing, it would have to be a main hose block, but i don't believe that is the case, i would have thermostat replaced, to confirm that, for a around 50 bucks (if you stay away from dealer) you can have the radiator flushed, which is a good idea anyway, then you will know for sure it is the thermostat, and they can put that in after they flush it, or you can put thermostat in, pick there brain, when they flush it, and they can point where it is, it is just a couple of bolts to take off, clean gasket area, replace with new gasket, after of course taking old thermostat out and replacing with new one.

I hope this helps you, (again, i think it is thermostat that is stuck) thanks Mike from fixya

You may have a blown head gasket thatis pressurizing the coolant system-pull radiator cap off and put a pressure gauge on it and see if pressure goes above 17.5lbs-cheers Denny

You still have a lot of air in the cooling system and you have to speed up the water pump to get any coolant to flow through the heater. Let the engine cool off, then open the radiator cap and top off the radiator. Pour the coolant in at a rate slow enough to let the air bubble up without splashing the coolant back out. Once you get the coolant level up to the top overflow hose, the remaining air will be pushed out by expansion through the overflow tank once the engine gets hot, and will be replaced by coolant from the tank on cool-down.

COOLANT-ADDING ADDITIONAL
Do not remove radiator cap to add coolant to system. When adding coolant to maintain correct level, do so at coolant reserve/overflow tank. Use a 50/50 mixture of ethylene glycol antifreeze containing Alugard 340-2 y and low mineral content water.
Remove radiator cap only for testing or when refilling system after service. Removing cap unnecessarily can cause loss of coolant and allow air to enter system, which produces corrosion.

COOLANT LEVEL CHECK
The cooling system is closed and designed to maintain coolant level to top of radiator.
WARNING: DO NOT OPEN RADIATOR DRAINCOCK WITH ENGINE RUNNING OR WHILE ENGINE IS HOT AND COOLING SYSTEM IS UNDER PRESSURE.
Remove radiator cap. The coolant level should be to top of radiator. If not, and if coolant level in coolant recovery bottle is at ADD mark, check for:
  • An air leak in coolant reserve/overflow tank or its hose
  • An air leak in radiator filler neck
  • Leak in pressure cap seal to radiator filler neck

Your overflow tank works on suction to return coolant to the radiator. Check the line and nipple ends for any cracking (cracking on the plastic radiator nippl is very commom). The radiator nipple is not under high prrssure like the fluid under the cap (inside the coolant system). It's on the otherside of the cap and will never "stream or gush" coolant (uless you are over heating badly). As the coolant in the radiator cools it creates a vacuum and draws coolant back from the overflow throgh a small hose. You might not see any leaks as coolant heats up and travels to the overflow. It might be a very small leak and you are usaully driving around and drying up before you see it. Even with a very small crack it will only draw in air and not liquid (as liquid is way heavier than air). Also, I've seen where people have taken out (or fallen out) the tube attached to the overflow cap that goes down deep into the overflow tank. That tube should be long enough to almost reach the bottom of the tank. It's hard to know if something is missing if you do not know it was suppose to be there in th first place but it needs to be there.

Heater in 2005 Caravan takes forever to heat and comes and goes


First thing to check is if the radiator and overflow tank are properly filled with antifreeze (with engine cool, of course) Next, is the temperature gauge moving up properly? If not, you probably need to replace the thermostat.
