Might have to file off some of the top of the fitting to clear the pressure cap

 

I'm not even sure it's tapered thread. Another "radiator " nipple I purchased a few years ago was not.

 

Good news/bad news.
New radiator cap purchased. Several test drives and burping sessions, and the temps are between 189-200. So that's good. I am guessing thermostat and water pump are working correctly.
But, when leaving Auto Zone, I saw a couple of tablesspoons worth of coolant on the ground, so there is a leak somewhere. Each top up is a little less coolant, but that leak is somewhere. The cap and tee seem dry as a bone after a drive and after the two hour cool down. No signs of leaks around the visible hoses or the thermostate housing. Maybe near the water pump?

 

It wasn't condensate from the AC?

 

It was orange.

Yes, look down from the top of the passenger side of the engine, look for coolant on top of the water pump, that’s where the weep hole is, also look at the ends of the transfer pipe the orings might be leaking, then on to the driver side at the thermostat housing block between the block and the engine

 

A few drops could be from the over flow tank filling up. After you shut the engine down the coolant temp rises for several minutes before it starts cooling down.

 

Thanks. I will check those areas, probably early next week as it's supposed to rain all weekend (and as established in an earlier post, I have no garage).

 

Stay dry!
