Venture Chevrolet Motor Heating

You have to try to readjust the clinter lid (cylinder head) If trying to readjust you see that the lid screws are lazy is there where the problem is (many times it happens)
greetings.

I thank you for all your comments, updating the subject I tell you that when the radiator's plug changing the antifreeze, the antifreeze no longer returned to the auxiliary deposit, but I realized that I began to escape liquid where I feel my head with the monoblock, it is a tear that is bare Checking the bayonet is clean the oil, the antifreeze with oil is not clean in the radiator.
The thermostat that changed opens at 90ºC and already verifies that the fans if both speeds work.
The head that is in the back does not see if it escapes how uncomfortable the engine is placed.
This leak will be enough to warm the engine and in a heated the start of the fans have been deprogrammed?,
Thanking their comments again and the time they give to my subject I wait for their recommendations, see you later and I send you greetings.

Ok. Then you found the fault, you have to disassemble your head, take it to rectify "just to be safe" that it is in good condition, put a new joint and re -install it with the right torque on each screw; I am sure that after this your fault will have disappeared, this fault is very similar to what happened to me with my Renault 5 (which I discuss previously) and the failure that Dexter23 comments in its multiple. But anyway you tell us the result.

Hi, hey, did you already solve the problem with the venture? Because perhaps the problem is in the admission multiple joints, it is very common in those engines, and if you want

I had the same case, even the vehicle sold it to me with that problem, I changed the temperature sensor, the relay, even when they sold me the vehicle, they had extracted the cable that sends the signal of a fan of the fuse box to make a direct connection ... The solution to my problem was to change the engines of the fans, because what happened is that they were heated and stopped. When changing the fans the problem was solved.
According to my personal criteria, it is that in the first speed the fans are in series connection, this makes them work at a low voltage that over time can damage them,
when the combustion engine is heated more, a relay connects the fans in parallel (I checked the electrical diagram of a manual)
sincerely in my case, I reconfigured the system so that between a fan to all its capacity and when the vehicle is heated Fan to all its capacity, I have been without problems for two years, where I live in May there are temperatures of up to 47 degrees centigrades to 70% relative humidity, and I can be in a bottling without problems.
