Cj Heater

sefh · 03-22-2006, 02:52 PM

I have a CJ that I mainly plow snow with and I'm in need of some more heat. What is the best to use? And where can I get them at? Thanks

Depending on the year of your CJ, the best approach is the blower motor upgrade (using a Chevy blower motor) and a new heater core. Mine really works well after I did this, as do others who've done it.

looking at your bio it apears you have an 87 CJ7 so yeah, the GM blower upgrade would be great. Also take the time to renew the seals and look for air leaks in the blower housing.

There are aftermarket heaters that work well but realy take more work to plum in the defrost and fresh air anyway.

I'll throw another vote out for the blazer blower swap. I just did mine a couple weeks ago.
The hardest part is getting the old stuff out. A dremel made quick work of enlarging the firewall hole for the bigger motor.
Now it literally blows dirt off the floor... And into my eyes

But it blows like a *&^%$@!

I did the blower upgrade and it darn near ran me out of the seat

I'm pretty sure that was a typo, because I'm fairly certain he doesn't have an 87 CJ.

But I second the blower upgrade. You can do it for less than 20 bucks. Mine works great. But, if you still need more heat after that, you can buy one of the auxillary heaters from any of the major jeeps places ( http://www.4wd.com http://jcwhitney.com have them). They are basically a second heater core with a built in blower. You just run some hoses to it and wire it up. Good luck!

My heater core went out last year and I didn't have a heater til this past fall of 05. I replaced the heater core, thermostat, blower motor switch and the blower motor (chevy blower motor upgrade). Talk about a major improvement. I never have to go past the middle speed (3 speed motor) and I'm toasty warm. More importantly, my wife is toasty warm and leaves her down comforter at home.

I would recommend replacing all especially since you're draining the radiator anyway.

I used a later model YJ motor. It really BLOWS too.

For the chevy blower motor

1973 Chevy Blazer with a 350 and no ac. Part # would be Siemens Part #102E

Make sure it's the one with a short shaft on it.

I have an 86 CJ not 87 so it sounds like a Chevy Upgrade would do wonders

Thanks for the input. Going to NAPA today to get one.

sefh · 03-23-2006, 07:00 AM

By the way I think I need to get new seals for the doors (frost up within 5 minutes) were would the best place be for those??
