heater hose attachments of one stuck Canuck

[bristar56]

1999 Ranger, 3 liter

- I have 2 heater hoses (incoming and outgoing) 5/8" diameter
- Branching off each heater hose (and attached to them) is a 1/4" hose going to intake manifold
- having trouble getting replacement hose or adapter tee to accomodate
5/8" to 1/4" hose
- if I replace existing heater hoses with 5/8" hose and don't replace 1/4" hose what will be affected
- will it be poor cold weather starts, poor performance until engine warm up
or worse

That's called the HWBP. Hot Water Bypass Modification.

You MIGHT notice a difference in the dead of winter, but I doubt it (depends where you live). Mine have been bypassed for years, but I live in a warmer climate. I've driven it in the winter in PA and WV and never noticed any problem.

Great answer Earl43P!! The link for HWBP should be on display at the Smithsonian. It's quick and easy
PS I live in the interior of British Columbia in the Okanagan Valley. Our winters are only a little bit colder than southern PA and WV.
If the Vancouver Canucks can't win the Stanley Cup hope it goes to your Carolina Hurricanes
My thanks to all!!
