Default Thermostat housing

Help....I replaced my thermostat last year and now its leaking around the housing it sits in! The thermo I got had a rubber gasket around it so I thought I did not have to use any sealer but maybe I should? Any sugestions??? Thanks in advance.

You can carefully check to see if the housing fasteners are still tight. If they are then you either have a fractured housing or need to replace the thermostat seal.
You are correct that a sealer in that area is not needed and since you have had a trouble free year of service sealer is not the problem.

X2 on that. The housing is a common part that cracks. Available OEM or parts store.

Yeah the housing is cheap plastic, same one thats on the neon actually. Which i have cracked with a light tap trying to unstick a thermostat.

If its not the housing, just change the thermostat again, sometimes the temp senor housing will get hot enough to warp the seal, causing a small leak :-D

After considering the time it takes to change 2 of these IMO these three things should all be changed together?

There's the t-stat housing and the 'connector' to the head.

The connector corrodes severely-
and as these guys have mentioned the T-stat housing loves to warp.

IF you need the connector I have one for sale on e-bay, I milled the surfaces so they're fresh;
ends tonite.

Neon 4884004AA PT Cruise Thermostat Housing / Water Outlet Water Neck Turbo Race | eBay

pluminator's right about being retrofitted on the Neon, we used to buy them new, but they've gotten downright expensive.

Quote:
2002 - CHRYSLER - PT CRUISER - - L4 - 2.4L - GAS
COOLING SYSTEM / COOLING / RADIATOR & COMPONENTS / Connector
4884004AA - Connector outlet adapter

MSRP $90.45
Otherwise if it's just the plastic housing you can work it so it's not warped, buy a new one from Chrysler (Dunno about the PT, but the Stratus isn't too expensive) or i might have one laying around that's of no use to me.

<-- When putting the housing on, turn it 180 from what the picture shows.
