Viscous Heater Delete

Developing a "Viscous Heater Delete" Kit.
Let me know if anyone else is interested in removing their VH for good.
Maintains belt geometry, allows use of OEM belt.
All direct bolt in place of OEM viscous heater, no modifications required.
Thoughts welcome,

Great idea.

I have been stocking up on spares including a Viscous Heater but a delete kit would be a positive addition especially if it uses the stock serpentine belt.

It will be a direct replacement for the viscous heater.
Will use stock serpentine belt and one rubber hose going from the thermostat to the viscous heater is removed from the thermostat and discarded.
Then the outlet hose is removed from the viscous heater, shortened about 1 inch and connected back in place to the thermostat where the first hose was removed. (supplies hot coolant to heater core)
Will post some pictures of new hose arrangement later tonight. :wink:

First is a picture of the new hose arrangement, coolant leaves thermostat housing and goes directly to heater core inlet no longer going through viscous heater which is no longer there. Second picture shows belt alignment. Worked a long time on getting the spacing/belt alignment just perfect.

Install is complete, no more viscous heater.
Additional pictures.
PM me if you would like to to get rid of your viscous heater.

Looks good,

Do you need to drain some coolant or can you just clamp off the hoses during install?

Thanks!
I was installing a new thermostat at the same time and lost about two quarts of coolant. Did not clamp off anything.
I just simply topped it off with some fresh G-05 50/50 mix.

If you were only doing just the viscous heater removal, you could be real quick on swapping the outlet hose from the VH over to the thermostat connection you should not loose hardly any coolant.
