DIY coolant bypass mod
DIY coolant bypass mod
Well after several attempts to sell these things I realized it would probably be better for me to share the information rather than trying to sell and ship these things. I will only fab for local people as to be able to do the install myself. Burping of the coolant system is not an easy task. I really dont want to be responsible for someone messing up thier own car across the country. Enclosed are several pics with narations along the way. Any questions feel free to pm me. mike

I think some people would have no problem installing it themselves. How much do you want for it? DM2 also sells one for $350 or so.

The install is not super complicated but It is more difficult on auto trans cars to get the rear most pipe off the heads... Also bleeding the coolant system in these cars can be quite the challenge. Mike and I have got pretty efficient in bleeding them.
Andrei not sure when you say hoe much do you want for it... This is the same setup as the DM2.

I'm surprised nobody showed interest especially everyone who is FI. It's worth getting rid of the clutter let alone 10 degrees. At least the motor wont feel heat soaked like it does every day this summer.
