I have found that when trying to undo the nuts on the pipes going into the chevy radiator for trans cooler that using a split ring or "Flare Nut" wrenches/spanners works better than normal open ended spanners, and don't even think about using an adjustable spanner on them.
All the original GM trans cooler is is either a small tin can (similar to a red bull can) that acts as a heat exchanger with the return flow engine coolant, or sometimes it is a coiled tube set up, all very cheap and cheerful and effective for normal driving or towing the hideously expensive tiny ERDE trailers from HALFRUADS but not much good for towing  caravans etc.


Clive, Please Please buy some extra security items for your caravan, Wheel clamps,hitch lock, big chains, big dog (thats why andyp hasnt got a caravan, who would be afraid of a susage dog !!!), Caravans are Oh so easy to dissapear off of your drive

Clive .....I fitted my cooler in around 1-1/2 hours. I run the fluid through the new cooler as most factory coolers that are part of the radiator pick up residual heat from the radiator.
If you want come round and have a look at mine. (I am only a few miles from you.) The radiator fittings on your van should be held in with a C clip and come of easier than trying to undo the nuts.

Hi ALL
Thanks for all the information Looks like i have spring clips on the cooler pips.
Andy F. or anyone, Do you know where to get the spring clips that hold the cooler
pip that goes into the Rad/Cooler.
Does the kit on the first page have to be different because of the spring clips
Thanks Ringotwinky

Hi every one
Those with a spring clip holding the return trans oil pipe from the top
of the radiator can remove this nut 1 ( and replace it with this one ) 2
The one on the left ( Use the fitting on the right 3 to screw back into the one you took out of the radiator . Put the rubber tube over each barb and tighten with jubilee clip
These fittings fit most 1991 and later FWD cars and 1995 and later GM trucks with 3/8 transmission lines ( FEMALE hosebarb threads on to factory transmission line ( MALE hosebarb threads on to the radiator
DONT KNOW WHERE THE LINK IS GOING TO POP UP Ringotwinky

Hi All
Have been lookin for some time for someone in US to ship these parts
Have now found one but shipping costs are high. Price for the two adaptors £12.00
Shipping £34.00 Im not to sure but if you take one of the fitting that came with your
cooler and cut the nut off you may be able to use it where the spring clip is.
With the other end you need to put a splay so as to stop the rubber hose coming off
Best of luck Ringotwinky

Hi all
IN THE LAST POST HERE I HAVE PUT THESE FITTINGS DONOT FIT
Today i was talking to a mechanic who rebuilds transmissions he told me that he
always diverted the trans oil away from the main radiator and in to one or two
trans coolers, His reason being he said, if the oil pipe split inside the radiator you would have water inside the transmission Room for thought.
All the best Ringotwinky

And if it splits outside you'd have air. Some choice

I think I'd still favour using the radiator in line with the aftermarket cooler due to it's ability to carry a lot of heat away. Think about it this way, if you have a lump of red hot steel to cool, do you plunge it in water or blow on it?

well for me ive tried towing with GM cooler standalone 228*F  this was a 50 mile motorway trip to blackpool

disconnected GM cooler and RUN standalone trans oil cooler (bout half radiator in depth n length) 260*F same trip as above same roads

so now my next option is to run in sync IE: connect back to GM cooler THEN piggy back the trans oil cooler HOPEFULLY thats gonna sort it

if NOT may look at same size cooler again to piggy back that to make the cooler bigger capacity OR an aftermarket electric fan set up on a switch



ive still had no feed back on how everyone else measure ur trans oil temp???surely some one is fitting some sort of gauge either digital or analogue

if NOT ur trans oil maybe running as hot as mine was in the aftermarket cooler alone sceanario 260*f or worse

and i hate to see anyone lose a transmission and £1500

Clive. I can't see any reason why you can't stick an aftermarket temp sender in the trans fluid line and fit a gauge.

Something like this is all you need:

Andy, That's just what I was thinking of doing, but until I add an aftermarket cooler I am not sure where to add the senser unit. There is only a short piece of rubber hose between the metal pipes and the oil cooler section of the radiator and I did not want to cut that without knowing what size of Tee piece I need to fit in it. Is this pipe 3/8 inch internal diameter, forgive my ignorance but my background is electrical not mechanical?

Forgive my ignorance too Phil - I don't know what size it is either but being a pipe the quote dimension is ID as opposed to tube which is quote OD.

If I was going to fit a sender to the standard set up I'd chop the pipe and silver solder a section of brass in there that was tapped to take the sender.
