Coolant Reservoir Fills, Doesn’t Empty / VSS Issue

[SAL]

Hey ERIC!
For my 1993 Toyota Camry 2.2/automatic with 153,000 miles… Two issues I hope you can help with: 1) 1000 miles ago I installed a new water pump (old one failed), timing belt (pulleys/etc), thermostat, radiator & cap. My coolant reservoir fills, but does not return to the radiator. I changed both reservoir hoses. I’m not losing coolant and the oil is clean . I dump it back into the radiator.
2) My speedometer was about 7 or 8 MPH slow. I installed a new VSS 250 miles ago. Using Garmin GPS, the new VSS is also 8 or 9 MPH slow. The transmission has always shifted & worked properly. Thoughts? Thanks!!!
Merry Christmas!

Did you install a OEM radiator cap or a aftermarket?
That would be the first thing I’d look at.
Then might do a combustion gas test.
As to your speedometer …
Do you have the original factory size tires?

— I had a new Stant cap, but thinking like you… I switched to the OEM with yellow Japanese sticker. I may just have to do a combustion gas test.
— On the VSS, I have factory size 195/70-14 Hankooks with 7500 miles on them. The original VSS has 22 teeth on the gear. Same as the new one. Maybe I got a dud new one out of the box. I’m stumped. THX.
