Sick Of Being Cold!!!!!!!!!
 
ok i have a 92 jeep yj 2.5 its my dd the heat barely works in it it has a new water pump and i high temp thermostat im thinking about replacing the heater core etc with replacement stock parts but first i want to know how well the stock heating system in these things works in perfect operating condition and if theres any modifications i can do to make it work better or an aftermarket heater or something that would give me better heat all i can find is a blazer heater motor swap but apparently thats onlyt for 91s and under i drive it in temps of up to -50 and it just sucks any info would be greatly appreciated and any tips for keeping warm in a yj would be greatly appreciated too :2thumbsup:

The stock heating system is very effective. I'd suggest you pull the hoses going to the core and flush the system first.

The "Blazer" upgrade, may not have any affect on your system, because at some time in '92 (I believe) they went to the bigger motor stock. The Blazer motor and the YJ replacement motor are one in the same PM-102.

Here's bunch of good stuff about heater systems from the FAQ..... http://www.jeepforum.com/forum/f12/y...6/#post8107902

Check your cable. I brought new blower upgrade, new tstat, radiator, heater core and even water pump before I discovered the cable that control the heat was binding real bad. I fixed that and the heat blows real hot like it never has in years. I didn't even need to buy all of that parts. At least I have those parts ready to go in case any of those parts croaked.

Just check everything and fixing heater is really easy, just pain in the *** to remove and put it back together.

could i just shove the end of a pressure washer in the hose that leads to it or would that be too much? how do itell if i have the good heater motor? apparently its an early build 92. cant find this anywhere else on the forum

I wouldn't use any kind of pressure beyond garden hose pressure if it were me.

X's2, I'm pretty sure if you use a pressure washer, you WILL be replacing the core.

At -50 I dont think any STOCK jeep will kep you warm.

WSTOF7 01-29-2010 07:40 PM
