I Overheated on the 91 getting towed home
Can you guys tell me what I broke

 

[RobertF]

Heater valve.
What yanked it apart, do you have broken motor mounts?

 

[skull_black]

don't think I have broken motor mounts just no electric fans and I wasn't watching my heat gauge and I think it just got too hot

 

[SanDiegoOverland]

i think you broke your finger look how it bends backwards. ..ewwww...



concur. heater valve.

 

[skull_black]

Thumb looks normal I think
So how much are these or does anyone have one sitting around

Just bypass it, they are known for failing just like that. they get brittle and then the pressure from the system makes them fail. I installed one in my jeep and 6 moths later it was leaking.

 

[homebrew]

heater control valve

 

[skull_black]

If I bypass it will I still have a heater

 

[WebDog]

Yup, and you wont have to worry about it ever failing you again.
Take a hose from pump to heater in firewall, and hose from heater to thermostat housing.

 

[GrimmJeeper]

bypass it or replace it with a metal one. the plastic ones always break, they get brittle pretty quick. If you can wait till saturday and email me while I'm at work ill get you a part number, I have to dig it up in a book.

 

[skull_black]

K ill do both ideas webdogs first
Thnx guys

I am about to bypass that thing on mine too. It will clean up that area of the engine compartment a little bit. I have had 2 of those damn things fail on me. I think they are about $17 or so at Vatozone.

last time i changed mine i broke the new one putting the damn thing in lol

I just broke my heater control valve too. Not wanting to spend $30 on new one, I bypassed the heater core completely. I just looped a hose from the water pump back to the thermostat housing. I figured I won't need heat for several months.

Scotty advised me not to bypass the valve by running the two hoses directly to the heater core. So I'd be interested in a metal valve too Mike, if you can get that part number.

 

[skull_black]

So got the plastic piece off. Now which tube goes to which tube LOL.

 

[WebDog]

on mine i have the hose from the thermostat housing hooked to the lower heater core inlet and the upper heater core to the water pump.

Why not? That's what I was gonna do.

 

[johnnyc]

Some people do it. Others don't. If I did it, Scott might disown me.

 

[skull_black]

That's what I did just now and now when I run it with the heater on instead of running at 210 its at 180 now lol

The heater core is not designed to be flowing all the time while the engine is running - if it was it would be that way from the factory. Without the blower running you are creating excess heat in the airbox that has no place to go, I can see it dramatically decreasing the life of your heater core :dunno:

Another disadvantage would be if it were to spring a leak, you would have no way to turn it off without shutting the engine off and bypassing it. I would take it out of the loop rather than just bypassing the valve - but that's just me. make sure you plug the vacuum line that went to the valve.
