Confirm if this is the thermostat bypass hose
Hey everyone. I have a '93 del Sol Si with a JDM GSR swap. I noticed a subtle smell of coolant in the cab when driving. When I looked under the hood I saw a tiny spray of coolant coming from pin-hole in the small hose that attaches from the thermostat housing to the passenger side of the intake manifold (using a Skunk2 GSR IM) where it mounts to the head. I believe that it's called the thermostat bypass hose. Can anyone confirm this? I've attached a picture. Thanks! https://cimg9.ibsrv.net/gimg/honda-t...cd066874c2.jpg |
Re: Confirm if this is the thermostat bypass hose
The bypass hose is the larger 5/8" L shaped hose in your photo. The smaller 5/16" coolant hose is part of the T/B and IACV de-icing circuit. This small port on the Skunk2 I/M just below the bypass fitting can be un-necessary in some applications, so you will have to examine what you have and how the circuit is run.

Re: Confirm if this is the thermostat bypass hose
I can confirm that it is the thermostat bypass hose. Went to the dealership and ordered the part: 19508-P72-000 I installed it yesterday. |
