You either have a leak in the hose or a hole in the themostat housing. Check the hose for holes first then tighten the hose clamp. If it still leakes then remove the hose from the thermostat housing and replace both the thermostat and the thermostat housing. Any more questions please ask.

99 Chev suburban 5.7 liter, antifreeze keeps leaking have to fill reserve and radiator evryother day, (new radiator) no white smoke, oil looks ok, cant see leak anywhere on the ground or frame??? Wheres it...


check the condition of the reserve tank and the hose from the reserve tank to the radiator for leaks if no leaks there have the Radiator cap presure tested . also this could be a air lock in the engine if the radiator is new with the engine running and the heater on hot observe the fluid level in the radiator with the cap off if it drops as it warms add more coolant this will purge the air .

Changed thermastat,spark plugs,new intake car is over heating during shifting is this my water pump 99 civic lx 5spd


can't necessarliy automatically blame the water pump, check entire cooling system related components , check air flow through radiator and condensor, often overlooked and plugged with bugs and road debris, check all hoses for condition especially for a collasped bottom hose due to your opening system to R&R thermostat... you may have to bleed air from your system ... check coolant condition for specific gravity.. clogged internally radiator, check flow with cap off engine cold pressure relieved watch flow to see when thermostat is opening... should have increased contant flow. check belts for proper tension and condition.

My 99 chevrolet suburban starts but won't drive


9 times out of 10 it is low on Automatic trans fluid. Please check the fluid and the condition of the fluid. If it is brown and smells burnt, but the trans operates ok after toping up, get the fluid and filter changed. If the trans slipps ( motor reves and car dowes not go) it is time for a rebuild
Good Luck

HYUNDAI TRANSMISSION


1. Drive the vehicle until the fluid temperature reaches normal operating the usual temperature [80-90°C (176-194°F)]. 2. Place the vehicle on a level floor. 3. Move the selector lever sequentially to every position. This will fill the torque converter and hydraulic system with fluid, then place lever in "N" (Neutral) position. 4. Before removing the dipstick, wipe all contaminate from area around the dipstick. Then take out the dipstick and check the condition of the fluid. The transaxle should be overhauled under the following conditions. a. If there is a "burning" odor. b. If the fluid color has become noticeably blacker. c. If there is a noticeably excessive amount of metal particles in the fluid. 5. Check to see if the fluid level is in the "HOT" range on dipstick. If fluid level is low, add automatic transaxle fluid until the level reaches the "HOT" range. Transaxle fluid: GENUINE HYUNDAI ATF SP-II, DIAMOND ATF SP-II or AUTRAN MMSP-II. Low fluid level can cause a variety of abnormal conditions because it allows the pump to take in air along with fluid. Air trapped in the hydraulic system forms bubbles which are compressable. Therefore, pressures will be erratic, causing delayed shifting, slipping clutch and brakes, etc. Improper filling can also raise fluid level too high. When the transaxle has too much fluid, gears churn up foam and cause the same conditions which occur with low fluid level, resulting in accelerated deterioration of automatic transaxle fluid. In either case, air bubbles can cause overheating, and fluid oxidation, which can interfere with normal valve, clutch, and servo operation. Foaming can also result in fluid escaping from the transaxle vent where it may be mistaken for a leak. 6. Be sure to examine the fluid on the dipstick closely.0f3ac6e.gif
