We did the combustion test,it was ok not exhaust gas ,cant really see the water pump but will look closer ...
it only burps does NOT suck from overflow..
Thanks for the insight ...... I was hoping for a easy fix .... I did buy the water pump but might be to much work for my guys , might have to wait til Hino shop has a open bay
Oh why delete the egr cooler ?? they want $995 just for the part ....
Yes I run these trucks and that pump has causes plenty of problems... sucks air, leaks fuel to get by add fuel to filter but change out ASAP....
Unless you want to pay the TOWMAN.... oh thats me ....
Need help .... I run tow trucks and put plenty of miles on them
I have a couple Hino 258 LP Great trucks !! love them !!
On one 2007 257 LP almost 500,000 miles
we replaced radiator and now after hour of driving it burps and over heats ...
runs perfect seems it builds pressure and burps...
