1051.0. "tranny cooler info, configuration" by SCCAT::SHERRILL () Mon Apr 19 1993 14:16

    
    Hello
    I have just purchased a 86 Dodge Ram Conversion to camp with and tow
    my 18 foot Wellcraft. The van has a 318 and I want to put a Tranny 
    cooler on the van as it get very hot in the central valley of
    California in the summer. The question I have what is the best way
    to install the cooler? Should one of the lines still go through the
    radiator or should the cooler be isolated from the radiator.
    I have called 2 tranny shops hand have heard conflicting stories on
    this. I think I will just go to Aamco and have it done but they are
    asking how I want it configured, but are suggesting I isolate the
    cooler. I will be buying the biggest cooler they have. I have looked 
    through this file and can't find any info on this. 
    
    Thanks
    
    Ron

1051.1	STILL USE THE RADIATOR	SWAM2::KLINE_ST		`Mon Apr 19 1993 20:23`	9
	hayden (tranns cooler mfg) and most of the trailer mags recommend that you go from the trans to the addon cooler then to the radiator then back to the trans. to find out the out line of the tranny feel both lines to find the hottest (= out line) or disconnect both lines and look for the one that spits fluid when you crank the engine. the recommendation for the routing is due to the need to allow the trans and fluid to warm up some on cold days. in this configuration the trans will not add to the overall engine coolant temperature and therefore the temp of the trans will be cooler.

	If you use the vehicle year round in warm climate, bypassing the radiator might be a little better. You won't need to warm up the fluid where you're located in the winter but, in the (hot) summer, bypassing the radiator would avoid adding additional heat to the coolant.
1051.3	its done,thanks for the input	SCCAT::SHERRILL		`Mon Apr 26 1993 15:49`	7
	Re.2 That's the way it is going to be installed. I am letting Aamco do it (lazyness has struck). The Aamco people said this is the best way to install it in this area. I will not be going onto the moutains in the winter with the van anyway. Also any added help to the engine cooling in this area is a plus.(100+ temps and some fairly long uphill climbs)
1051.4	Check out the RV conference	GUCCI::HERB	Al is the first name	`Tue Apr 27 1993 09:17`	6
	I don't know what kind of fan you have on the van but you might want to look into either a flex fan (blades that change pitch at different RPMs) or an electric one(s). Look around for the RV conference. You should find plenty of opinions about towing there.

	Some of the cooler companies offer thermostat kits that help solve the too cold fluid problem... Carl
