hello and thanks for tuning in if you're new to the channel please hit the subscribe button
if you're returning thanks it means a lot all right we're back at the ram 3500 turbo diesel
and i wanted to look at some issues with the cooling system and how we're going to address
them so we're going to go up under the engine compartment now and a common issue that we see
here is the flattened upper radiator hose and you see how it sucked literally sucked thin right here
i mean it's it's got such a vacuum on it it's ridiculous so there's a solution for this we're
gonna get everything out and laid out and i'm going to probably end up changing that thermostat
to a 180 t-stat because this truck is deleted so let me get all the items laid out and let's
get to the install this in this is with the 200 degree thermostat 57 degrees out it runs between
195 and 200 well basically 190 and 200 bounces between there when you're driving
dodge had a tech tip that you could change these thermostats to 190
but seeing is deleted and tuned i'm no longer needing the high temperatures in my engine
and that's why we're going to the 180. so let's get everything laid out and put in
okay and as we can see now after a drive the thermostat hose is nice and
round when it cools down it'll suck back down and i don't like that so
let's get this thing changed out is let the motor cool down take the radiator cap off and open the
drain valve and drain down some coolant below the upper radiator hose so that we can get the
hose and thermostat housing off all right after draining about a gallon of coolant down
i'm going to come up and take off the two band clamps on the upper radiator hose here
and you can squeeze it to make sure it's empty let's get those clamps off and get this hose off
we got the stock hose off and you can see it's clear off there let's get the thermostat housing
off and you can see still steam coming off because i just sprayed it down cool um water
because cooling got on the belt and i didn't feel like having the belt get all sticky so let's get
this thermostat housing off it's three uh eight millimeter bolts i believe or five sixteenths and
we'll just pull it straight off now you may have a harder time because you may have an egr tube here
i don't so it's very easy for me but if you do i believe you got to remove that egr tube to change
the thermostat but don't quote me on that press that housing off don't forget to disconnect your
coolant i'm sorry your turbo coolant feed line and let's go over and look at the other thermostats
so this is the original cummins one that i pulled off it's a 200 degree
kind of dirty looking going back with a murray plus it's a 180 so it's 20 degree difference
only difference is the placement of the air bleeders in here those are on each
side and this is on one side so we'll drop the thermostat back in get the housing back on and
we'll take a look at the new coolant pipe there it is the sinister diesel upper radiator hose
solid metal i believe it's it might be steel i'm not sure i think it's steel mild steel
but we'll get it on there comes with great clamps uh and new silicone hoses to attach the radiator
and the thermostat housing so let's get this thing on and see how it looks okay there it is installed
looks beautiful the it's a very tight fit as far as getting hoses on and those
clamps as you see i have the threaded part towards the valve cover away from the fan
and these facing this way away from the hood for when i close it we'll get it filled up and we'll
go for a test drive and see what attempts are a few degrees colder outside but i don't think
that has any effect on the coolant temperature because the engine once it gets stopped operating
after everything's heat soaked i didn't see temperatures over 190 and i was boosting 34 pounds
throttle to the floor so definitely definitely an improvement here i'm gonna step out open the
hood and show you guys one issue i found with the uh clamp that sinister sent me
all right the clamp that went on to the thermostat housing was definitely too big and it leaked
coolant so i had to go back with the factory stock clamp i will call sinister tomorrow and
see what the deal is and see if they'll send me out a new one and i'll change it eventually
yeah definitely a nice upgrade for the truck pipe gets warm just be careful
with it no leaks no nothing everything works good so thanks for watching please subscribe
