DennisB DenLorsTools.com © Summary: Toyota Camry Toyota Rav4 and Highlanders with the 2.4 four cylinder engine has a very common problem with blown head gaskets due to the aluminum threads in the block failing for the head bolts. The middle three in the back of the head are usually the weak point. However, we recommend installing all 10 inserts to strengthen the threads so that it will be less likely to have a repeat problem. Most of the work is getting the head off, so why not spend a little more time to upgrade all the threads? Below are some of our most common questions when it comes to doing this type of repair. Read on for more information or continue to the TIME-SERT 2200 product listing. Read the rest…

DennisB DenLorsTools.com © Summary: Toyota’s with the 2.4 four cylinder engine have a common issue of blown head gaskets because of the aluminum threads in the block failing for the head bolts. The middle three or four in the back of the head are usually the weak point, which can become stripped. However, we recommend repairing all ten holes to prevent having a repeat head gasket failure due to stripped threads or pulled threads. This also prevents the possibility of the threads failing during the torque process right after putting the new gasket and head back on the block. This can be very frustrating and has happened to our customer’s more than once! Vehicle’s affected are the Toyota Camry, Rav4, Scion, Highlander with the M11x1.5mm head bolts. The repair system that we recommend, the Time Sert 2200 can also be used in any engine that has M11x1.5mm threads because it is a universal kit which can be used on different hole depths.

DenLorsTools.com Summary: Motor vehicle air conditioning questions answered from all over the world by a master air conditioning technician in Florida. Simple to understand terms are used to resolve issues and to help the reader understand problems with their car’s Air con system (A/C system). Low gas (refrigerant) is the most common problem a car’s aircon system could have, but it’s not always the issue. One shouldn’t assume that the solution is always to top-up (top off) a system. A re-gas that adds too much R134A only causes more problems. Many garages will do a free pressure check. However, simply checking the pressure readings is not a foolproof test of the air conditioning system’s health. But, a knowledgeable motor vehicle technician can make a good evaluation of the A/C’s performance based on the readings and a visual inspection of the components. After evaluation, a ragas (recharge) may be done or a more accurate fill of refrigerant can be performed by removing the remaining refrigerant, vacuuming the system down and recharging with the vehicle’s specified amount of gas.
