My car keeps overheating...

[Temos]

It started last night when my sister said she heard a noise and smoke came out. I got a friend to take me to where my car was and he saw that the lower radiator hose popped loose. He put it back on and filled it up and everything seemed fine. This morning, I was taking someone to work when it said 'check engine temp'. I pulled it over, waited and put more coolant in. I drove to my friends house and he looked at it again. He put in a new thermostat and now there's a leak. I'm going to take it to a shop in the morning, and I'm wondering what to expect to pay. Let me run it down real quick:

After repairing the hose, the engine started to over heat.
My friend was looking at it, and said the top hose was warm while the bottom one was cool....which might be a sign of a bad thermostat.
After replacing the thermostat, there's a leak.

Thanks for the help.

You need to properly burp the cooling system, that is why there is that cap on the black tube....

I don't understand what you mean. Which hose should I check to burp it?

The metal tube, it has a cap with a 1/4" female socket... stick a 1/4" ratchet in there and remove the cap.

Then remove the reservoir cap.

Fill at the crossover until the reservoir is full and then put the reservoir cap back on

Start the car and continue filling through the crossover tube until the car gets warm, the bubbles stop coming out, and it is full.

Put in the metal cap back in and tada, your cooling system is burped.

Thanks so much. We were just out there for 30 minutes and the temp stayed normal. He went to a mechanics school and said that they never showed any of them how to burp the cooling system. Apparently they had a machine that did all the work for them. So the good news is, my car no longer overheats, this annoying noise coming from inside the hoses is gone, and I can use my heat again. Thanks a million bud, you saved me so much money from going to a mechanics shop.

No problem... the 4V mod motor is a very unique motor as far as the cooling system goes...
