1989 Esprit SE Expansion tank cap?

Recommended Posts

I am so sorry to have to post a whole thread on this. I did in fact use search for "expansion tank cap" and "Radiator cap", to no avail. I own a 89 Esprit SE, and just got it running again after removing both fuel tanks and replacing all of the fuel hoses, vacuum lines, and any easy to replace engine gaskets. after running the car for a bit i heard the expansion tank cap hissing in my ear as i was in an odd position changing around the routing of some lines / hoses.

i would like to replace my expansion tank cap, but the "STANT 10203" for a Jeep Cherokee was not shown as a good part number at the parts store. they gave me a STANT 10229 and 11230 for a late 1980's Jeep. neither will fit the expansion tank, but they about the right diameter for the charge cooler tank, but have a 15 and 16 pound rating.

anybody have a part number for the expansion tank?

thanks you.

Michael

thank you, i will call them Monday if i cannot find a local cross reference.

turns out my expansion tank has a very small leak at the bottom seam. i am going to remove it today to take to a radiator shop and be welded on Monday.

i thought there would be a local, over the counter part because JAE is on the other side of the country and it takes several days to get anything shipped from California to Georgia.

i took many pictures of the removal and installation of the tanks and all the lines as gaskets i did, car should be trouble free after this.

Hi Michael,

I am facing the same jobs on my 89; I'd appreciate seeing your pictures.

Yours,

Tom

ok i called the dealer in Atlanta Georgia thinking it would be easier, since JAE has to get some of thier stuff from them anyway, and i am already in Georgia. the cap came as part number A082K6042F and it will not fir the expansion tank or the chargecooler tank.

has not anyone here ever replaced their expansion tank cap?
