Underbody Coolant Leak on Chrysler Town & Country

Coolant leaks coming from the underbody on vehicles equipped with rear heat/AC are common. The underbody hoses should be inspected as part of regular maintenance. If you drive on roads where salt is prevalent the problem is generally more severe. Some 2005 models are involved in a special service action, no government recall was issued.

I walked out the door to start-up my 2002 T&C EX van on a 0 deg. February 2015 morning only to find a large puddle of engine coolant under the van. I immediately thought I had popped a block freeze plug. I traced the leak to a corroded steel tubing set which turned out to be the supply and return coolant lines to my van's rear heater. Living in the Northeast (outside of Philadelphia) with all of the snow and salt greatly accelerates corrosion on vehicles. After doing some research on the Internet, I found this heater tubing corrosion problem is quite common with Chrysler and Dodge vans. I purchased a replacement aluminum heater hose tubing set (Dorman #626-301) with rubber end flex hoses and clamps from my local Advance Auto store for about $70 (via Advance Auto online coupon). Good to see Dorman designed an all aluminum heater hose tubing set versus Chrysler's all steel tubing set. I also bought a cable operated hose clamp plier ($40- Sears Craftsman) to loosen the nearly inaccessible ten or so hose clamps. These pliers were INVALUABLE! I took me nearly two days to complete the repair as I was covered in snow about two hours into the job on the 1st day while the temperature was about 20 deg and had to quit two hours later. Not exactly ideal working conditions. The most difficult parts of the job were: 1) removing and installing the many hose clamps (nearly impossible to do without the specialty pliers) and removing/installing the old and new tubing sets. Clearance is a #$%&*! Don't attempt to do this repair unless you have the right tools, right weather conditions, and the right "frame of mind". I may have saved myself $500-$700 doing this labor intensive repair work but I now have numerous cuts, scratches, and a little bit of frostbite. Oh well, I will heal.
Hose blew out and dumped coolant
Bought car in Feb.2011 and in June A/C stopped working. Called Chrysler and they told me this wasn't a problem, however that was not true. Now because it has corrosion in the compressor my warranty won't cover the repair costs. Cost to repair is a whooping $1200. I do live in the Midwest where we have snow and they salt the roads, but really were they not expecting anyone who gets snow to buy their vehicles! This should be a recall!!!

Coolant leak all over the driveway. Took it into the shop and were told that it was the radiator. We just had the radiator replaced two years ago for the same problem. Paid to have the radiator replaced again and brought it home. Two days later, same problem, coolant tank completely empty and a huge puddle driveway. Taking it back into the shop since this is the reason we brought it in in the first place.

A/C was working for a week or two then would lose coldness. Noticed antifreeze on ground on driveway. finally figured out that connection between metal tube and rubber hose was bad due to corrosion from road salt.

Metallic Coolant hoses are made of cheap white metal, that rapidly corrodes. Fix, replace all metal hoses before you wind up broken down on the road.
Rusted from rear bracket to up the firewall. The weld changed properties of the metal, wrong welding process used.

Had a leak in my antifreeze from back undercarriage of my van. Going through a gallon of coolant once a week. Then find out my freon is gone from the leak. Costing me over 1,000.00 to get fixed.
