Anyone know what code 37 is. I'm having a cooling system problem.

 

Code 37: Torque converter clutch solenoid circuit or park/neutral switch failure.

that has nothing to due with cooling. does your Neon just over heat or does it only do it sometimes? nd code 35 actually has to due with cooling cause its the fan relay is bad.

 

No, it overheats quickly, and loses coolant somewhere, but doues not drip. fan is not operational, though.

 

the fan not operating would be code 35 for the fan relay. its a common problem on Neons.

 

I think the fan is simply unplugged. I run normally at idle, but it overheats at speed, ans loses cooland , but does not leak, that I can see. No oil in water, or vice versa, no smoke from tailpipe. All coolant is gone after 30 minutes of driving.

 

blown head gasket

 

i think it's time for a MLS HG, good way to check for leaks is with coolant pressure tester. if you do alot of work on cars it's a good idea to buy one, or take it to a shop and they can do it.
