Among other things.
Now that my truck isn't going to mainly be used in the winter I wanted to get it tuned up and ready for hot weather hauling duty (pulling my new to me 5th wheel). As I posted awhile back, my thermostat was stuck open not allowing the truck to warm up - at first I thought it was the Coolant Temp Sensor because the needle would just sit and never move, but finally while driving with my plow in the raised position, I noticed that the needle moved and almost got to normal operating temps. My heat was also very weak in the truck.
So I purchased a new thermostat- stock 190 degree, some coolant, some new spark plugs, tranny fluid, tranny filter, trans temp guage, a new belt and some hoses.
I've read online about guys who have done this but could never find pictures of where the thermostate was housed. I found it and took pictures, also included in the thermostat is a small metal ring with a rubber gasket on the inside of it which I had no idea where that was supposed to go- well I found that and took a picture.
So Here is how it went-
- Place 5 gallon bucket under the passenger side of the radiator by the lower radiator hose.
- Loose Lower radiator hose where it connects to the radiator.
Caution - When you remove the hose a LOT of antifreeze will come out FAST. Be ready for it and direct it all towards the bucket
- Drain until it basically stops by itself and re-attach the hose to the radiator.
- Remove the upper radiator hose from the radiator- this will have coolant as well, I cut the top of a Milk Jug and stuck the hose on it to collect the coolant.
- Remove the smaller 5/8" Hose that attaches to the Thermostat Housing (I had to cut mine)
- Remove the Upper Radiator hose from the Thermostat Housing ( I Had to cut mine)
- removed the intake tube (probably not necessary, but I did it to check the air filter anyway)
- Remove the bracket that connects the Altenator to the A/C Compressor (has 4 bolts, I believe they are 14mm and 12mm-that could be off I can't remember right now).
- Remove both bolts holding the Altenator in place, lube up the mounting spots with some WD40 to help it come loose.
- Use a star sock/torx socket to relieve the belt tension on the tensioner and take the belt off the altenator. ( I was replacing my belt so I removed it completely)
- Remove the bolts holding the Thermostat Housing in place- Note - You will need to push the AC Hoses aside very slightly, be careful not to kink these.
- Using a hammer or whatever, tap the housing lightly until it comes loose.
- Pull housing out - clean the gasket material off of housing
- Remove old Thermostat - clean gasket material off of engine surface, place rag inside so it doesn't get into the engine water jackets.
- Remove metal ring with rubber gasket from inside the thermostat area inside the engine - I had to tap it with a flat head screwdriver and hammer until it dropped. Then I had to reach in and pull it out.
- Replace metal ring with rubber gasket with new one.
- Replace Thermostat
- Replace Thermostat housing Gasket
- Replace Thermostat Housing
- Reattach hoses, reattach Altenator and belt, and reattach bracket.
- Fill with anti freeze/water, and run motor. Open radiator and allow air to escape - burp the system.
Hope that helps, here are the pictures!
