I just discovered I seem to have this issue. I have been smelling coolant, and I found what looks to be a leak coming from the same area. I don't have the PZEV radiator noted in this thread. Does anyone know if this can be temporarily solved with a radiator stop leak product? And if so, which product is best? Holiday time is terrible for another big car expense/radiator replacement.

 

IMO, I wouldn't go with a stop leak. are you able to do it yourself?

Nissens radiator is 145, Peak Global Lifetime will be about $25 from Walmart online (one jug of concentrate should work), you'll want to grab some replacement radiator hose clamps. I'd say the whole job would be about $175 all said and done.

 

If it were summer, I'd entertain the idea of doing it myself. But it's cold and I don't have a warm garage space either. Here's my newly discovered problem: My Outlander comes with the factory towing package, and the radiator part listed for it is not the part listed everywhere online. The only one I can find online is the one most people seem to have: 1350A050. Well, mine is 1350A490, and I can't find it anywhere but the dealer suppliers for $730-ish. I have no idea what the difference in the radiators could be, and I'm hoping the shop I take it to can modify it. They all use the same hoses, so how different can they be? The diagrams of the radiators look the same as well. Anyone know these two parts' differences? Capacity only? If that's the case, I definitely don't care. Have never towed anything with it.

 

I found this old thread. Wondering the name of the sensor that is being discussed when replacing the radiator?

 

They were discussing a sensor tied into the PZEV radiator, which was only installed on California models. The only other sensor I can think of would be the coolant temp sensor, but not sure where that is mounted.

 

Thanks,
Oh, OK. I am in Texas and have owned mine since new and did not know anything about that. Also mine seeps out the top at the upper hose connection that appears to have 4 bolts that connects upper hose neck to radiator. I found this to be weird that the upper hose connection bolts to rad. I have never seen one like this. I am thinking I can unbolt connection and make gasket and use sealant to reseal. It seems to seep some overnight but not too bad. Just trying to avoid getting new for now.

 

I was told those necks are prone to cracking by a Mitsu tech. I replaced mine at 11 years old. It's to keep the cap in the system and not part of the formed radiator. Engineering wise, the radiator can fit into many models and you only need a plastic piece to locate the cap wherever under the hood that fits.

Easy to fix.

 

Easy Fix? By that do you mean to replace radiator or remove neck and reseal?

 

Replacing the filler neck is easy if that's your only leak. The part was inexpensive, too. Don't bother with a leak stop additive, just get a new filler neck.

 

Thanks. It is not the filler neck. It is the upper hose connection that has 4 bolts.
