Question about Dodge Caravan

1 Answer

No visable leaking, always smell coolant when motor is hot, outside of the 2003, 3.3liter grand caravan. Gauge will read half way after 3mins on a cold start, takes about 8mins for any heat to come from the heater.

If you smell coolant then there is a small leak, it is most likely the water pump shaft seal, look for stains, coolant leaves a white powder when it dries, look on the underside of the hood for any coolant stains from it been flung there by the spinning water pump. Also have a radiator pressure test run, good insurance aginst an engine overheat if leak worsens, engines are very expensive to repair if overheated badly.

My 2006 Caravan temperature gauge goes to red - engine is not overheating. Kick it into a lower gear (automatic trans) and the gauge comes back down. Is it likely the coolant sensor?


Could be.. is the system FULL? Air in it can cause some odd things. When engine and coolant are COLD (as in after sitting over night), open the radiator cap. Top off the overflow res with a 50/50 antifreeze / water mixture to HOT mark. Start engine, turn heat to hot and fan to high. Top off RADIATOR with same 50/50 mixture slowly & gradually. As the coolant circulates, it should bring any AIR trapped in the system (from heater core & engine block) to the radiator where you can replace it with the 50/50 mix. Once the coolant is HOT and stays level - about an inch under the opening, close the radiator. Monitor the overflow res and add as needed. Good luck!

Car smells like it is running hot but gauge doesn't show its running hot. I don't see anything leaking from underneath and have checked fluids. Had to have the thermostate replaced a couple of years ago...


This could be due to a leaky heater core. The heater core corrodes and starts with a tiny collant leak that smells collant inside the car and washes out with the A/C water when the A/C is running. This water/coolant mix drips out possibly over the right side exhaust pipe creating the "hot coolant" smell outside. At the begining you won't notice the coolant been lost, but later the loss will be ovious.

Heater on my 05 Grand Caravan blows cold air when below 30 degrees - above 30 works fine. Heat gauge shows normal so it shouldn't be thermostat. Checked coolant and it is fine.


just because the gauge seems normal doesnt mean the thermostat is good, its 5 years old,and may be opening to soon, i would start by having the t-stat replaced and while thats being done have the cooling system flushed including a flush off the heatercore. i ve worked on a couple of these vans with heating problems, most were low on coolant due to a slow waterpup leak, the others with half plugged heatercores, due to the lack of coolant flushes. hope this helps.

No heat , antifreez leak not visable...


A car this new should have a warranty right? the only other place for anti-freeze to go is through a blown headgasket into your oil. Pull out your oil dipstick and make sure it is not milky in color. If not check behind the engine and see if any coolant lines going into the firewall are leaking. When inside the car do you smell steaming coolant(anti-freeze) or hear gurgling? The temp gauge that stays on is the overheat indicator?

My honda accord wagon smells hot i stop running car, ther,s no leaks do i need a termostat?


You may have a bad thermostat or a weak water pump or a clogged radiator. Smell does not indicate if its hot. The gauge or coolant light might suggest its getting hot. You may have a fuel control issue that is overheating the catalytic converter which would smell or an oil leak that is dripping onto a hot surface causing a smell. You may have a real small coolant leak that you cant see that could cause this also.

Engine smells like rubber burning and temperature gauge at normal temperature. Water/coolant leaking out of reservoir and needs to be filled ever 2 days. Oil level is normal, but when it's hot outside the...


Generally that smell is caused by an oil leak that is getting on either the exhaust pipe or manifold (doesn't take much to smell). As far as bottle getting low, I've got a 93 that never stays full but only needs coolant in the radiator about once every two months. Been like that for two or three years and has never overheated. I'm sure there is a small leak somewhere, but I'm not driving myself crazy looking for it. Check all hose connections, and look on the ground after being parked overnight...If it's leaking, something will show up. But if the radiator is staying full, just check it when checking oil level.

Engine oil mixed in coolant


this would more than likely be cause by a bad cylinder head gasket. I would bet 89% this is your problem.
