2005 Corolla LE when to flush coolant and change hoses, thermosta
2005 Corolla LE-4 years old. Mechanic recommends changing coolant hoses & flushing coolant & replacing thermostat, gasket & radiator cap. My car has been well maintained in NH. Is that necessary or are they just looking to make some money? Nothing is mentioned in maintenance manual except in the back "inspect and replace as necessary".

Changing the hoses, thermostat, and rad. cap on a 4 yr. old car is not necessary, I believe u are correct that this 'mechanic' is out to make some money by creating work. Find someone else to work on your car. Curt

You can buy a flush kit from your local auto supply store to add to your cooling system for this and future flushing. As for changing your thermostat - simply remove the thermostat housing - remove the old thermostat - replace with new (be sure it is the one rated for the season at hand) - replace gaskets (or use RTV gasket maker) and reinstall housing. Fill the system with proper % ratio of coolant to water (usually 50/50). Drive away happy.:) PS You can find your thermostat housing by following the top rad hose from the rad back to it at the intake manifold.
Sounds like air in system, repair any leaks flush and add universal antifreeze, and to get air out without special equipment, fill best as possible, start engine drive around block. Let vehicle set until cold. Then check coolant level again, repeat until guage stays normal
HeadGasket Changed still the same ? I Will tell you first it take's alot of flush.. best thing is put the Water Hose on one side and the other side unplug to flush it, it will make a mustard color residue ! If after flushing everything and everything is clean and it seem's to be the same.. might be a Water Pass in the Block Cracked near a cylinder or a Bad Head.. ! For that check your 4 Spark Plug's check if one is really white or cleaner than the other's, check compression on each cylinder ! Should tell you where is the problem ! He might change the HeadGasket but didn't check if the head was straight and not cracked !
many things can make this happen I would inspect all hoses to see if none are collasped Also change the thermostat and coolant if not done in the past two years. Flush the old coolant out with a flush kit made by Prestone or equivalant You may see a big change in performance. If not a blockage can be in the heater core or radiator but I don't think so for this vehicle is 4 years old only
Sounds like you have air trapped in the heater core when you flushed the heater core. loosen the upper most heater core hose and run the engine untill coolant seeps out. Wait until the coolant has reached running temperature.
