Coolant Hose TSB - Which Hoses?

[tosugrad]

All,

I am getting ready to replace all the coolant hoses on my '91 with 31k. I see that the previous owner had TSB 92030 done which replaced 3 hoses (6k ago), as per the FAQ section. Can anyone tell me which 3 hoses these are (part numbers) so that I dont replace them again? Thanks!!!

Thanks for the info. Unfortunately this TSB does not give specific part numbers as to which of the coolant hoses were to be replaced. I am trying to find out which exact ones (part numbers) so I do not replace them again. Anyone?

The TSB details the hoses for this with part number/etc for a hose kit. It clearly shows the undertray hose in question. Did I miss something??

HTH,

Larry,

The part number is for the kit. It is not clear how many hoses are in the kit. It only details the one underneath hose. There are about 11 hoses in the system. I am just trying to find out which ones were replaced in the TSB. Thanks!

The TSB references a kit, and the illustration only indicates the following hoses...
HOSE, WATER MIDDLE (UPPER) 19518-PR7-A00
HOSE, WATER MIDDLE (LOWER) 19519-PR7-A00

each hose is approximately $30 each

I will try and post what I consider a total list of hoses soon.
