Question about Toyota RAV4
Hello. Regarding the oil leak, it is not uncommon for cars to leak oil as the oil pan gasket ages and deteriorates. If you want, you can replace the gasket with a new one, this will stop the leak.
Regarding the radiator, you could have it flushed. This will remove any partial block and give you a clear understanding of what kind of shape the radiator is in. It is unusual to have to replace a radiator unless the vehicle has over 250,000 miles on it.
Finally, regarding that temperature issue, just replace the thermostat. As these things age they often cause the symptom you are describing. A new thermostat is a ten dollar item, easy to replace. Call your local Walmart auto repair shop and see what they charge. It should be only about $20.00 installed. Joe

Hi this could be lots of things to cause the temp gauge to rise quickly, the worst scenario would be the head gasket might be blown, there are 3 ways to test this, 1st, check the oil filler cap if it is a gunky beige colour this could be a sign the head had blown, 2nd, run car, open expansion bottle, and sniff it to see if you can smell fuel in it,3rd, compression check pots, get a compression tester, remove spark plug, disconnect leads from coil pack or distributor, turn engine on a few times, and measure the compression between the pots, if it shows low, on one or more the head has blown, the other thing it would use a bit of oil if head gasket had blown as well, the other things it could be , stuck thermostat, run car till it gets hot, squeeze the bottom hose and then the top hose on the radiator, if it is hot in the bottom hose but cold in top, its a stuck thermostat, oil leak could be lots of things, here are some for you to check, rocker cover gasket, cam shaft oil seal, distributor ( if it has one),head gasket, power steering fluid ( check hoses and rack gaiters) this should be enough to get you started...hope that helps
