Hello fellow Previa owners, I can't thank all of you enough for all the posting and sharing of info to help keep my car going. I've used this TVT before to figure out problems and buying parts like the SAD shaft from Timsrv (thank you again, It worked great !)a year ago. I'm now poised to buy and install a leaking water pump for my 91 Previa with 275,000 miles on it. It is an amazing car. I was going to look for a Beck Arnley pump as suggested by Timsrv. Am I splitting the pump in half or replacing the whole thing ? Should I replace the thermostat while there ? Anything else I should be looking for ? Also, how/where do I find glass headlights ? Lights are dim even after the polishing scam I tried. I guess I should finish the pump before I start another project or search this great forum more. Thanks again.
