Jeep Repair Problems? Ask a Mechanic for Answers ASAP
Hello and welcome to Just Answer, my name is Matt.
When you replace the water pump, what procedure did you use to bleed the cooling system?
I just removed the waterpump and coolant came out, after that just topped it off, did not flush
on a side note I drove it to cali from az with no problems, but on the way back at about 7 hours is when it happened
Are you near the Jeep now?
it is down stairs
OK, look on the engine, right where the upper hose connects to the engine, there should be a threaded fitting. This is the bleeder for the cooling system.
On the 3.7L and 4.7L engines, it is very important to remove this fitting when refilling the cooling system. It is very unlikely the air will purge out without removing this bleeder fitting. It requires a hex tool, 8mm if I remember correctly.
so i should remove this fitting, with the engine off, to let the coolant equalize?
first take the radiator cap off so the system is not pressurized. Then take the fitting out. Add coolant to the radiator until it begins to flow from the bleeder hole. Then reinstall the bleeder fitting (with sealer or teflon tape so it does not leak). Then start the engine and top off the coolant in the radiator. Now the system is bled, no air. Then top off the coolant bottle.
can do, so you dont think there is any problem with the transmission?
Maybe. Sounds like the engine overheated pretty good. I probably would replace the thermostat since it got so hot. Then do the bleed procedure I explained above. Then hope for the best. If the engien seems OK, then have the trans fluid changed.
ok I will give this a try.
Thanks for using Just Answer. Reply back if you need more help.
Another thing....what kind of coolant are you using? Keep in mind that your Jeep needs orange coolant, not green.
wow, that was the best $18 i've spent in a long time
oh, im using the green kind, its a "universal" although i try my hardest to stay away from universal things, i was in a bind and thats all they had
universal should be OK
where is the drain for the radiator, on the bottom driver side
I would not open that unless you have to....sometimes they don't reseal properly...then you're in a pickle
I always just pull the lower hose off
ahh, good point, well i just drove for about 5 miles, half with a/c and half without, and the temp is holding stady
this is after doing the bleed procedure?
i would have never thought to do that
the radiator took almost a gallon of coolant
OK, hopefully all is well. Keep an eye on the temp gauge and the coolant level.
Overheating can damage the head gaskets...hopefully this did not happen!!!
oh i will, stupid me, after i changed the water pump, i just added coolant to the resivoir, not the radiator
Live and learn, right?
i will drive it to school and see how it does, 45 minute ride to school
its strange how we drove it to cali (la then to san diego) no problems, and it over heats like 5 miles from my house
That is hard to explain.
it is indeed, thankyou
