Hi guys....
I looked around here for a definitive answer to this question but I can't find one...so here it is:
For those of us who live in climates where the temperature can get very cold...say -30ish...is it worth keeping the Thermostatic Tee on the fuel filter or not?
(It also gets very hot here in the summer so it's kind of a catch 22.)
Pro removal Comments:
- Cold fuel is easier for the IP to pump as warm fuel is thinner
- The Tee is a known weak link. They can crack or the seals go bad...which lets air into the line and also possibly leaks fuel
- Properly treated fuel does away with the need for the Tee
- If the fuel is going to freeze it will do so in the lines as well as anywhere else. If no fuel is flowing the Tee won't help anyway
Con removal Comments:
- It was put there for a reason by engineers who know better than us
- Other diesel engines also use them (CAT for example)... so again it must be there for a good reason.
- It warms the fuel in the filter in cold weather, thereby eliminating gelling or gelled fuel from the filter which would reduce fuel flow
So if you live in a cold climate is it worth getting rid of the Tee?
And do the new TDI's still have the Tee? Or are they doing something different?
Thanks guys
