    Cooling Mod

    Dennis:

    Had the cooling mod installed in June while I was in your shop. It has now turned colder here in Delaware and I'm having heater woes. I can't seem to get enough heat from the heater, regardless of which mode, or temp. that is selected. The heated air also turns cool when at idle, or as the rpm starts dropping below 2K. Since I don't know how the mod was actually supposed to be installed, I looked around. One head is joined into the return line from the heater, the other is joined into the supply line. Is this the way it was to be installed? Any input would be helpful. The temp gauge reads mid range, so it appears the engine is at the correct temp.

    Thanks for your help!

    I doubt it since the mod was installed in June '04.

    I just had a member call me on the phone who was considering this mod and asked if I had a similar heating problem. For one I live in FL and have never turned on the heater till I tried it for him. After driving about 1 mile from my house I turned on the heater and instantly very hot air came out. It was also 83 degrees outside at the time, but the air was still very hot to make me think it was working properly. Sorry I don't live more north and freeze my ass off enough to try it out under more chilling circumstances.

    First of all I need to know if the car in question has my transmission cooler on it, if the OAT sensor reading is off for example if it is showing a warmer OAT than what it realy is the heater will be effected, the rear cooling mod should not lower the heater out put because the water temp does not change that much we are just talking about better water flow out the back of the heads,

    Dennis:
    I'll give you a call later this morning. FYI, no I "Do not" have the transmission cooler. Only your cooling mod, and tranny upgrade. As far as I can tell, the OAT seems to be working okay, but we'll talk about it. What I don't understand, is why the heated air turns cool, or even cold, while at idle.

    I have the kit on two cars here both heaters will run you out of the car, I would look and see if a hose is pinched, also let the car warm up and put your hands on both hoses going into the dash/heater core and see if there hot, and call me when you can.

    Bob/Marauder03,
    What is the good/bad word on your lack of heat in your car? Was hoping you would post the outcome of your trials and dealer visit.

    Okay, here's the latest, good, bad, or indifferent. The temp coming off the heads is 190 deg. The hoses "do not" even get hot enough where you can't keep your hand on them. The bottom raditor hose, even setting in the servcie bay and reving the engine never really get hot. The wrenches at the dealer are going to replace the pullies, like a dummy, I didn't get my old ones from Dennis, so will have to buy new ones. Will then replace the pullies, and the thermostat with OEM stuff and try again. Until then, I'm still without heat. Don't get me wrong, I have warmth, it just won't get hot, and at idle I have nothing.

    Head cooling mod, underdrive pulleys with upped in-gear idle for low voltage - no heat problems yet. It'll put out HOT air at any rpm / speed if I want it. We'll see when it gets really cold.

    Bob,

    A couple thoughts:

    Have you tried just the "vent" setting? My MM's climate control seems to get a little goofy with the climate control in "automatic" when its cold out. The automatic temperature control / fan speed still works, so I've just been leaving it in vent unless I need to defrost then I manually switch it.

    Also, has your svc dept pulled a vacuum on your cooling system and pressure tested it to make sure you don't have any air in the system?

    - JD

    I have stock pullies I will overnight them to you, but I do not feel this will fix the problem, normally with UDP the car may run warmer do to the larger WP Pulley, since the pump is turning less. But lets give it a try if they think it will help
