![]() toyota red fluid filled to top of radiator and coolant bottle to max mark.ģ). So I think I have a problem, but having issues tracking it down.Ģ). I'll need to check further since the fluid in the overflow is about 1.5 inches below the max line even though the radiator and bottle were capped off before their use. One video I found showed the pressure going up gradually when the engine was running and stated that if it oscillates a little that there is a head gasket leak.Ĥ). My fault in this was forgetting that the radiator pressure tester wasn't designed with pressure relief in mind- its purpose is to record pressure and not release. when I ran the engine and watched the pressure it gradually increased to 30 psi (the redline is greater than 30 psi) and was trying to go higher. ![]() I sprayed the tool, hose and pressure cap to radiator with windex soapy cleaner to see if there were any bubbles and I didn't see any.ģ). So I think that for this slight drop it could be that the pressure tool doesn't form a tight seal and may be leaking in the tools hose although the tool itself is brand new and was never used before. However, when I recheck the fluid level in the radiator it is still full, and the overflow bottle level has not changed. That is, when I set it to the pressure tester range of 13-14 psi, and wait for about 15 minutes, the gauges drops down about 0.5 to 1 psi and stays there. I tested the radiator pressure and it will hold pressure about 1 psi below max radiator cap pressure. I tested on a second new radiator cap from NAPA, and this one losses pressure pretty fast and won't hold past 7 psi.Ģ). Moreover, my old and new radiator caps won't hold pressure past 11 psi vs. The radiator cap will release pressure when it goes past 13.25 psi. I rented the MT-300 with the foreign adapter from Autozone and did a pressure test on my cap and new CU21 radiator.ġ). The alternative is to buy the camry manual trans and/or the 1992 corolla OEM factory radiator cap. The reason is that the depth of the radiator hole for the cap is 1 1/16" and the original Stant 10241 doesn't extend this deep so it wouldn't hold proper pressure in the CU21 radiator. This is the same as the 1992 Corolla auto/manual trans radiator too. If you have a manual trans and the proper manual trans radiator, or a Spectra 1 row aluminum CU21 radiator (which is for the auto trans) the Stant PN# is 10227. This Stant PN# is if you have an automatic trans and a Camry OEM radiator. The Stant replacement radiator cap is Stant 10241 at 13 Psi. Has anybody used the OTC bladder tool on any Toyota model and year? I rented the autozone which is the Motorad MT-300 and the foreign adapter which is supposed to be universal although I think it is only for the radiator and not the cap.Īs for the advance auto, Harbor freight versions they are all the multi-color plastic adapters and am not sure if the work that well as the metal ones from Stant. The manual transmission adapter #'s are different. For the 1990 camry V6 with automatic trans the cap tester is Stant 12024 and the radiator adapter is Stant 12025. These all add up since the simplist ones are about $20 and the others are in the $60-80 range each. The Stant has specific adapters that are bought separately and don't come as master kit. The OTC version doesn't require all the various adapters although it won't work on Kia, Jeep or Saturn models for some reason. The OTC 7991 bladder version and the Stant 12207 model that uses adapters. Ive been looking at two different radiator pressure testers.
