Overheating Radiator & Auto trans

[guchev]

I'm not a mechanic so just looking for some advice! Went in some mud at Rover...sh*t stuff! Ever since then my rad and Auto trans are starting to badly overheat. Assume rad because of mud in fins etc...which I'll clean off. However am I right in saying that the Auto also has a cooling fins at the front of the vehicle and these could be caked also? Car is an 06 Patrol with 6.5 diesel chev in it and 4L80E transmission. Any pointers or other views would be great.
Thanks.

id say your radiator is full of sh*t
does your auto have a remote transmission cooler ???
if so it will be full also
the gq autos have cavities inside the radiator to keep auto cool,not sure on your model

remove and clean both items and you will back to normal
I removed my radiater after doing the same and removed about half a kilogram of mud and silt

Told you I'm not a mechanic!!! Sorry... However, there are other finned coolers in front of the rad. Would this be what you are referring too?

When I clean them is it ok to use water blaster on the rad?

yea any of the hoses at the local car wash would be fine to use spray a bit of degreaser in there first let it sit a few mins then hose out champ.

on your gu should have your radiator (you know that much)thats good
infront of that should either be your air cond radiator or a transmission cooler
if its got factory air it will have air cond radiator
to check if its got remote transmission cooler,ly under car and follow your transmission lines,if they go into radiator then no you dont have remote transmission cooler
if the lines go into a seperate type radiator then u have a transmission cooler
the fins in the radiator dont take much to block,gunna be a pain cleaning it all out,best to take the whole lot out and give a proper clean as just simple hose wont remove it all
keep an eye on your temp guage when done as i would expect rebuilding a cooked 6.5 would not be cheap

Be CAREFUL with a water blaster as they can bend the fins of the rad (and trans cooler).

Take them (both) out, lay them flat and just use a std garden hose using the water just soaking off the mud as much as the water pressure. If you just karcher them in situ (still fitted to the car) you run the very real risk of bending the fins and THAT will cost you some serious money.

Hope this helps.

I agree with this, a slow soak over a long period is better even if it takes longer.
