Heater ?

It's been a little colder than normal down here in Florida and I have began to realize how much the heater in my D90 SUCKS! I will be traveling north for the first time during the winter and was wondering if the radiator/grill covers help increase the heat. I don't want my family to be frozen while on vacation.


Thanks
Rico

New water pump does wonders. Pull all the crap off that is blocking the flow of the vents. It was 22 today here. Stayed warm with a crappy original soft top from 94.

It does help get and keep the engine to a proper temp. Other wise it will run a little "cooler". Just make sure that it is cold like high of 35 for the day.

Check the heat adjustment cable going into the engine bay. If you are blowing cold air, could mean the cable hasn't opened the heat all the way. I thought mine sucked until I checked. Now it blows hot instead of warm.

Tomorrow morning is the best I can do, but it's pretty simple. The heat level cable goes through the bulkhead and connects to the heat control in the engine bay. The cable connects to a lever that if not pushed (or pulled) - can't remember which direction, - all the way, won't give you max heat. Once I got the heat maxed out, I don't touch the control switch till spring.

no rush at all, I wasn't planning on messing with it anytime soon.

My heater was working marginally at best. I changed out the heater core when it started leaking and now the heater works great. The old one was very corroded inside, so not much coolant was circulating through it.

Mine was a leaky thermostat causing the engine to never get above 160F, new thermostat and it runs at 195F again and pumps out good heat.

Here are some picts as requested. The cable sticks and doesn't open up the lever, so it helps to manually extend the line and push the arm all the way out. I read how to do this here and it has helped make the heat output hotter. I've tried to lube the line and assembly to get it to work properly, but still sticks. Sorry for the dirty engine compartment pics. Rausch Creek Mud is a PITA to remove! Also, Waxoyl is a magnet for dust and mud

Still cold when you get in, but that is what seat covers are for. Might invest in some nice sheepskin ones eventually!

I have a dingbat question - do you have to pull the whole heater box to replace the core? Or can you drain the fluid, pull the heater hoses and then unscrew the core?

Am I totally off here?

At least on my RHD 110 you had to pull the box to get to the rivets on the back side. No way to open it up in place. It's not hard to remove the box though.

Thanks Charles - I think that's the way it is with mine. That's a project for the spring, though.
